THE Spider Crabs form a small but interesting part of the Decapod Crustaceans collected by the "Endeavour." They number twenty -seven species, nine of them new, and one representing a new genus. The most notable are the new species of tin- deep-water genus Cyrtomaia, with its formidable armature of sharp spines ; the long-necked Ephippias, having an exaggerated first ambulatory leg, and combining the characters ol two subdivisions of the family Inachidae ; and five species of Leptomithrax, including one distinguished by a smooth round boss on the merus of the outer maxilliped. Mr. Allan R. McCulloch had begun a report on the crusta- ceans, and later kindly sent me the drawings which he had prepared. The originals of PI. xv. and Fig. 2 were drawn by Mr. J. Si. K bighorn, of the Australian Museum, and of PI. xiv. by Mr. McCulloch. The remaining drawings were made by Mrs. R. E. Gamble, and the photographs by Mr. J. H. Paine. Order DECAPODA.

An ovigerous female was taken on the eastern slope of Bass Strait in 70-80 fathoms. This specimen has been compared with a male from Port Jackson, in the United States National Museum, and received from the Australian Museum. The female has a shorter neck than the male but agrees in other respects. The eggs are numerous and of large size, about 7 mm. in diameter, the carapace of the mother measuring 8.7 mm. long and 6.7 mm. wide. Genus ACHAEOFSIS, Stimpson. ACHAEOPSIS THOMSONI, NornuDi.

Carapace very finely roughened with sharp granules. Three gastric spines, the lateral spines being very long, slender, sub-parallel, and in a plane almost at right angles to that of the cardiac spines ; median gastric spine further back than the lateral pair and very much smaller. Two cardiac spines side by side, shorter than the median gastric spine. Two dorsal branchial spines (paired) the posterior and smaller almost in line with the cardiac spines, the anterior spine lower down and almost in line with the median gastric spine. Besides there is a marginal line of small spines which is continued on the pterygostomian region, and a short, parallel, submarginal row of similar spines at the widest part of the carapace. Two marginal hepatic spines (paired), the anterior of good length, the posterior small. Rostral horns slender, moderately divergent, about twice as long as the interantennular spine. A large tubercle on the upper surface of the eyestalk at its extremity. Basal antennal segment armed with four spines ; the stoutest is at the antero-external angle, points forward and has a spinule near its posterior base ; the others point down- ward and outward, the second spine on the ventral surface near the inner margin, the other two on the outer margin.

The " Endeavour " specimens were all taken in the Great Australian Bight, off Eucla, as follows : South by east of Kuela, Long. 131 E. 5 200-250 fathoms ; one male, two females. k About one hundred miles south of Eucla, 120-1(30 fathoms ; two ovigerous females. South by west of Eucla, Long. 126* E., 130-190 fathoms ; one male. Sixty to eighty miles west of Eucla, 80-120 fathoms ; one ovigerous female. Remarks on the type-specimen. In order to comprehend this species I examined the unique type female at the British Museum in August, 1914. Several discrepancies between the specimen and the figure in the " Challenger " volume above cited were noted. The length of the carapace on the median line is 37.3 mm., the width 35.2 mm., that is the carapace of the figure is somewhat too long. The narrowest part of the rostrum at the constriction, just behind the lateral spine, is 4.3 mm., while below r that point the width between the down- ward-pointing teeth is 5.8 mm. The figure docs not repre- sent the inferior width. The propodus of the second ambu- latory leg shows in reality an inner margin slightly concave and more spinous than in the figure, while the outer margin measures 41 mm. and is densely and finely spinulous. The merus joints of all the legs are slightly concave on the inner margin. The merus of the third leg is rough to. the touch. 8 ENDEAVOUR SCIENTIFIC RESULTS. A special feature of this species LS the presence of an out ward -pointing, transversely-placed spine on the inner margin of the upper sinus of the orbit, or at the posterior end of the preorbital lobe. This spine is not present in the species figured as P. wyville-thomsoni by Alcock 6 or by Doflein.7 In the type-specimen, the carapace is covered by numerous granules, a few of which are enlarged into tubercles ; the only spines are around the anterior border or on the anterior part of the branchial regions. The two branchial regions are well separated from each other. Xotes on the Australian specimens. The chief difference between the specimens taken by the w ' Endeavour " and the type-specimen is the enlargement of the more elevated tubercles into small spines, as follows : 4 on the gastric region, of which 2 are median and 2 in a transverse line a little in advance of the anterior of the median spines ; 2 cardiac, arranged transversely ; 1 branchial (paired) in line with the gastro-cardiac suture ; besides there are a few smaller spines or spinules, e.g., 1 branchial (paired) in front of the above-mentioned, 1 or 2 gastric (paired) not far behind the orbit. The ambulatory legs of the male are considerably longer than those of the female. $ $ MEASUREMENTS.

The name P. turbynei Stebbing 9 cannot be applied to the above form because it is differentiated by the characters set forth by Stebbing ; e.g., the propodus of the penultimate leg of turbynei is about twice as long as the same article in the young male of similar (larger) size of P. alcocki.

F0t7T7r/(>t//j>f j . - Carapace with the regions well delimited, the branchial regions approaching each other, the cardiac region small, the hepatic regions prominent, the intestinal region prolonged backward in a stout, blunt process. The more elevated portions are tuberculate : The principal tubercles are, a pair in a transverse line on the anterior gastric region : two, median, mesogastric : a number on the cardiac region chiefly grouped on two conical elevations side by side : a band of tubercles on the branchial region extending from the inner angle obliquely backward to the lateral margin : those on the surface of the intestinal region which include five or six of the largest tubercles of all. These are deeply pitted, as is also the broad, blunt end of the intestinal prominence. Hepatic region trispinose ; the upper, marginal spine projects directly outward, the submarginal, anterior spine projects forward, while a subhepatic spine points obliquely forward and is visible in dorsal view between the other two spines. The anterolateral margin of the branchial region is armed with short blunt spines and tubercles arranged mostly in a double row. The postorbital spine is triangular, acute, and is a little nearer the eye than it is to the hepatic region. Rostrum cut nearly to its base into two long liat, gradually tapering, acute, and slightly divergent spines ; the upper sin-face is longitudinally concave in the middle, the outer edges of the two horns are subparallel or slightly convergent, inner edges fringed with long straight hair, lines of curled hair above which are continued backward on the carapace. Kyes rather long, stout, enlarged at both ends, curved, much as in Gamposcia retusa Latreille. 18 Kye sockets circular. margin smooth except for a small tubercle below, on the basal antennal joint. This joint is longer than wide, longi- tudinally furrowed in the middle except at the distal end. where it is armed with a strong spine pointing downward, forward and slightly outward, and partially visible from above. The anterior angles of the buccal cavity are produced in a blunt tooth ; above and in front of these angles there is a short spine. .Merus of outer maxilliped at its widest point as \\ide as the ischium ; palpus coarse, articulated at the inner angle of the merus.

First ambulatory leg of enormous size, over twice as long as carapace and correspondingly stout ; a short, blunt spine at lower, distal end of ischium ; next three articles rough with low tubercles or nodules ; dactylus longer than propodus, compressed. The legs diminish in length and stoutness from the first to the fourth : the last three pairs are nearly smooth ; the dactylus is distinctly shorter than the propodus ; the second leg is much stouter than the third and fourth. Female. The carapace is wider anteriorly in proportion to the length than in the male, the ''neck being shorter and less conspicuous ; the aiitennal spine is slenderer and more outstanding, the post-orbital spine is slenderer and is directed obliquely forward a little, the anterior of the hepatic spines is longer, slenderer and hooked inward a little at tip. The rostral horns are broken off near the base and are missing, but the stumps appear narrower and less flat than in the male. The posterior hump is slightly developed and overhangs the posterior margin of the carapace but little. Chelipeds slender, especially the chelae ; arm with various tubercles above in addition to the three spines of the male : chelae almost filiform, the horizontal fingers less than half as long as palm, and narrowly gaping in basal third only. The first ambu- latory leg is estimated at no more than twice as long as the carapace ; dactylus a trifle longer than propodus, both measured along the dorsal line. The second ambulatory leg is not so much stouter than the third as in the niaie ; in the .second, third and fourth legs there is more difference in the length of dactylus and propodus than in 1 he corresponding .articles of the male.

Twenty miles north-north-east of Double Island Point, Queensland, 30 fathoms ; one male. Measurements. Male holotype, length of carapace to end of rostrum 10.7, length on median line 10, width 10.8 mm. Description. Carapace covered for the most part with crowded, forward-pointing granules ; they are absent in the anterior middle portion, which is clothed with long hair. Hind part of carapace depressed, especially in the line of the gastro- cardiac suture. Longitudinal impressions limiting the meso- gastric and anterior cardiac region deep. Rostrum short and broad, ending in two broad, arcuate lobes separated by a narrow emargination. Chelipeds rough like the carapace, the right one the larger : they are lobed and spined as follows : a broad lobe on the inner margin of the ischium and another on the inner margin of the merus in its proximal half ; merus proximally carinate above, carina high and faintly bilobed ; a short, stumpy, erect spine at distal end of merus ; a large, curved spine at inner angle of wrist ; two large serrations occupy the upper margin of the nianus. A reddish-brown colour covers the immovable finger and the distal half of the dactylus, except the tips. Legs cristate along upper margin of merus, and feebly so on upper margin of carpus and propodus of last two pairs. The crests have an uneven edge, ending in the merus of the first three pairs, in a short distal tooth above, and ha vino; a tendency to form a shallow tooth at the middle of the same crest.

REPORT ON THE AMPTIIPODA. INTRODUCTION. The collection of Amphipoda made by the F.I.S. "Endea- vour" contains thirty-four species, and although there are only two of these that I have described as new, the collec- tion is of very considerable value, affording- additional information on species already known and particularly on their distribution. The most interesting is Endevoura mirabilis, nov. gen. et sp., which, in the greatly enlarged propod of the first peraeopod, appears to differ from other members of the Lysianassida 1 . The re-discovery of Ephippiphora kroyeri, White, from the type locality enables this fine species to be fully described and restored to its proper place in the group. It will be seen that an increas- ing number of the forms have been identified with species previously known only from European seas and the North Atlantic. I am greatly indebted to Miss E. M. Herriott, M.A., assistant at the Biological Laboratory, Canterbury College, for preparing the drawings to illustrate this paper and for much other valuable assistance.

The peraeopoda are normal, the basal joints widely expanded, the posterior margin in the fifth distinctly serrate. The uropoda and telson show a close general resemblance to those of Waldeckia obesa, Chevreux. (See Pigs. 1 h and i.) Fig. 1 h i. h. Third uropod. kriiyeri White. Telson. The branchiae are large and bear a number of transverse folds on the upper portion like those in Anonyx nugax, Phipps. I did not find any "accessory branchiae," but was unable to make a full examination in the single specimen I dissected. It is evident that the genus Ephippiphora is very nearly related to Socarnes, as Boeck stated when he established that genus in 1870. The resemblance of E. kroyeri to Waldeckia obesa, Chevreux, a species which I consider the same as W. zschaui (Pfeffer), is so close that the two should, I think, be placed in the same genus, but at present I leave them as they are and the discussion of these genera must be held over for some future occasion.

These specimens agree well with Stebbing's description and figures which apply how- ever only to the female. In the male the second antenna (Fig. 2) has the flagellum greatly elongated and is fully half as long as the animal, the penultimate joint of the peduncle is longer and broader than the ultimate and widens a little distally, the ultimate joint narrowing dis- tally; there are only a few fine setae on the peduncle and the liagellum appears to be without ealceoli. In both sexes the proximal joints of the fiagellum of the upper antennae bear transverse rows of sensory setae which appear to be as numerous in the female as in the male. In 1912 (p. 473) I stated that this species occurs in New Zealand. Comparison of specimens shows that the New Zealand form differs a little in the characters of the third uropoda and should, perhaps, be kept separate. Epliippi- phora kroyeri. White, and Waldeckia obesa, Chevreux, have the third uropoda nearly alike, but differing from both the Australian and the New Zealand forms mentioned. NANNONYX KIDDERI, (S. I. Smith).

Stebbing has since suggested the establishment of a new genus, Parawaldeckia, for its inclusion. The present specimen, which is a male with greatly elon- gated tiagellum to the second antenna, appears to be quite the same as the type specimen of Lysiannax stcbbingi, G. M. Thomson, which was obtained at Pirates Bay, Tas- mania, and with which I have compared it. In the "Endeavour" specimen the telson (Fig. 8 //) has the pos- terior margin transverse \vith two setules at each posterior angle. Mr. Thomson's type is mounted permanently so that the telson is seen in side view and the posterior border cannot be made out, but it shows the two setules at the Fig. 3 a b. Nannonyx kiddei'i (S. I. Smith), male. a. Third uropocl. >. Telson. angles as in the "Endeavour" specimens. In Socarnoides hergueleni, Stebbing, which I have considered to be the same as the present species, the angles of the telson bear setules but the margin between is rather deeply indented or cleft. I give also a drawing of the third uropod (Fig. 3 a). If all the forms I have grouped under the name .V. kidderi are rightly included, the species is widely distributed in Australian and New Zealand seas and in Subantarctic regions. AMPHIPODA.

Bay of Fires, Tasmania, 10 fathoms. Many specimens. 3 mm. long ; deep salmon coloured ; eyes reddish. I think these specimens must be referred to Stebbing's species, the type of which was obtained by H.M.O.S. 'Thetis" off the coast of New South Wales,' 54 to 59 fathoms. In some respects, however, they differ from Stebbing's description and approach still more nearly to T. sarsi. Bonnier, as described and figured by Sars under the name T. nana (1891, p. 76, pi. 27, fig. 1), and in my opinion Stebbing's name must be considered a synonym. The depression on the fourth segment of the pleon is not quite so narrow and deep as that shown in Stebbing's figure, but in some specimens at least it is well marked, while the posterior part of the segment is distinctly keeled. The variation in this character is sufficient to make one doubt its importance as a specific distinction. Stebbing states that in the second antenna the antepenultimate joint of the peduncle is, "contrary to custom, longer than the penultimate.'' This, however, is not the case in the 'Endeavour" specimens, in which it is either shorter than, or equal to, the penultimate joint. The second gnathopod has the hinder angle of the hand not so acutely produced as shown in Stebbing's fig-ure, but more like that figured by Sars for T. tarsi; the finger again is hardly "small and weak" as described by Stebbing-, but agrees with the figure and description given by Sars, who speaks of it as being ''rather strong." The peraeopods agree with Stebbing's description in having the basal joint large in comparison with the rest of the limb and the merus ("fourth joint") more expanded than is shown in Sars' figures. Stebbing describes the lobes of the telson as bearing three lateral spines instead of two as in T. sarsi. In some of my speci- mens, however, there are certainly only two lateral spines and, as stated below, there may be three lateral spines in T. sarsi. I have compai'ed the "Endeavour" specimens with speci- mens sent to me years ago by M. Chevreux from Le Croisic, 44 "ENDEAVOUR" SCIENTIFIC RESULTS. France, named "Tryphosa nana," and I cannot find any reliable character by which the two sets of specimens can be distinguished. These specimens from Le Croisic agree on the whole with the description and figures given by Sars, but have the fourth segment of the pleon in some cases at any rate distinctly keeled, while S'ars describes his species as being easily known "by the absolute want of any dorsal projection" on the fourth segment of the pleon. The Le ('roisic specimens, however, seem to show, just as do the 'Endeavour" ones, that this character is by no means constant, but is subject to considerable variation in speci- mens collected at the same place and time. Tu the peraeopods again the Le Croisic specimens agree in the expanded meral joints with the "Endeavour" specimens, though the basal joint is perhaps a little shorter in proportion to the rest of the limb. In one of the Le Croisic specimens again the telson has three lateral spinules as in T. cam el us instead of the two mentioned by Stebbing for T. sarsi. The two species described by Sars under the names of T. nana- and T. Tforinfjii are united by Bella Valle. and in this I am very much inclined to agree with him. He, however, considers them to be the same as Anonyx nana, Kroyer, which is considered by Stebbing to be a different species and is included in "Das Tierreich" Amphipoda under the name Orchomenella itauus (Kroyer). It should be added that Walker in 1904 (p. 244) described, on a single male specimen from Ceylon, a new species, Tryphosa cucttHata. which, he says, "is distin- guished by the peculiar hooded character of the peduncular joints of the upper antennae." At the same time he recorded the occurrence in the seas of Ceylon of Orchomr- nella nanits (Kroyer) which had been collected in a dif ferent locality at a different time.

The third peraeopod (Fig. 4 ?.) has the side plate very large, deeper than broad, lobed below, the posterior portion widely expanded, oval, anterior margin fringed with setules arising from slight serrations, posterior margin with minute crenulations. The merus is produced postero-distally into a rounded lobe. The fourth (Fig. 4 m) and fifth (Fig. 4 n) peraeopods are of similar shape, the fifth slightly larger than the fourth, the basal joint narrower than in the third, and with the posterior margin somewhat irregular in outline, slightly concave towards the distal end and with minute crenula- tions. The third pleon segment has the infero-posterior angle quadrate, the angle itself being produced into a short point. * In another specimen, subsequently examined, the palm projects much more and the limb might he described as chelate.

In the "Endeavour" specimen these (Fig. 5 6) have the general characters found in males of similar genera and have the flagellum elongated to about one-half the length of the body. The eye is large and oval. The first gnathopod is similar to the figure given by Stebbing, but is considerably longer and more slender ; the second gnathopod is also long and slender, agreeing well with Stebbing 's figure and description. Stebbing 's specimen, which was a female, was obtained in the South Pacific near the Kermadec Islands at a depth of 1,140 metres. In the first antenna (Fig. 5 a) the first joint of the flagellum is very long and bears on the under side numerous short transverse rows of fine setae, the joints of the flagellum bear calceoli and are twenty-three in number, while the accessory flagellum contains nine, of which the first is the longest.

The type specimen, which was a female, was taken off the Kermadec Islands, and the species is now for the first time recorded from the Australian coast. Fig. 5 d. Euonyx normani, Stebbiug, male.

These specimens were found along with numerous other Amphipoda collected at the same time. After examining them and comparing them with New Zealand specimens, T have no hesitation in referring them to this species, 'S'. typicri, which has hitherto been known only from a very few small-sized specimens from New Zealand. There are altogether five species described of the genus 8ebu, all of them somewhat imperfectly known. In two of ilie species the male differs from the female in the shape of the first gnathopod. In the male the propod of the first gnathopod is expanded and the palm shows various projec- tions or teeth with concave depressions between them. In the female the propod is much smaller and has the palm produced so that the limb is distinctly chelate, the inner margin of the fixed finger i.e., the palm being straight or almost so. In his account of S. antarctica "Walker (1907, p. 37) pointed out that the male of that species differs from the female in the posterior peraeopoda, which had the meral joint very much broadened and ex- panded posteriorly. Walker speaks of his species as having dimorphic males, some being similar to the female and distinguished from it only by the absence of incubatory lamellae, the others larger and differing in the expansion of the meral joint of the last three pairs of peraeopoda: though, according to "Walker's account and figures, these large males have the first gnathopod similar to that of the female. In N. xica, Ohiltou, male. a. First gnathopod. b. End of palm with tip of finger (more highly magnified) . oblique instead of being transverse, though the armature of the palm itself is closely similar ( Fig. 6 a and b) . I find, however, that the small specimens collected by the 'Endeavour," measuring only about 2 mm. in length of body, have the palm transverse as in the New Zealand speci- mens, which are of about the same size, and, as in them, the meral joint of the posterior peraeopoda is only slightly broadened. Transitional forms are also found, and it appears evident that the expansion of the meral joints of the peraeopods is greatest in fully developed males and is gradually attained, and that in young males the palm of the first gnathopod is transverse or even projecting, while in the larger or older males it becomes gradually more and more oblique. The expansion of the merus of the fifth peraeopoda increases in proportion to the greater oblique- ness of the palm of the first gnathopod. Probably in quite young males the first gnathopod is similar to that of the 58 ENDEAVOUR SCIENTIFIC RESULTS. female ; I haA^e one small specimen that I presume is a young male which has the first gnathopod almost the same as in the female, but with the palm more nearly transverse and slightly irregular. Among the "Endeavour" specimens there is no female bearing eggs, but there is one specimen which has the first gnathopod similar to that described by Stebbing for 8. saundersii or to the female of 8. armata as described and figured by Chevreux. It has the first gnath- opod distinctly chelate and the distal portion bent inwards in a different plane from that of the basal half, so that it is difficult to get the whole gnathopod in view at one time. Individuals with the first gnathopoda having this same chelate form were found by Walker in S. antarctica bearing eggs, and we may therefore presume that this "Endeavour" c d Fig. 6 c d.

In 8. antarctica Walker speaks of dimorphic males, but as the two forms he describes differ only in the amount of expansion of the meral joints of the posterior peraeopoda they are probably rather to be con- sidered as different stages of development. In 8. antarctica, therefore, the males appear to differ from the females only in the great expansion of the meral joints of the posterior AMPHIPODA. CHILTON. 59 peraeopoda. In his figure of the whole animal Walker (1907, pi. 13, fig. 22) shows the meral joints of the third, fourth and fifth peraeopoda all equally expanded. In the "Endeavour" specimens of S. typica it is only the fifth peraeopod that has the very marked expansion and in some specimens the joint is produced posteriorly more than is shown in Walker's figures (see Fig'. 6 c) ; in the fourth peraeopod (Fig-. 6 d) there is considerably less expansion, and in the third still less, the meral joint showing- the same amount of dilatation as in the female. In 8. artnata, as in S. typica, the male differs from the female in the armature of the palm, the projections and teeth being similar to those of the latter species, but the propod is markedly produced so that the giiathopod is distinctly chelate. Chevreux gives the size of the males examined by him as scarcely 3 mm., and it is possible that they were not fully mature, and that older specimens would have the palm more transverse or even obliquely subchelate. The male figured by Chevreux shows no expansion of the meral joint of the last peraeopod: either it is not yet developed or the species differs in this point from S. typica. As Walker lias already pointed out, the females of all the species described are practically indistinguishable. Seba f ij pica" is known from Xew Zealand and from Bass Strait between Australia and New Zealand. $. saundersii Stebbing, with which 8. typica was at one time united, and with Avhich it may ultimately prove to be identical, is known from Cape Virgins, Patagonia, and, with some doubt, from Algoa Bay, S. Africa. S. antarctica Walker is known from South Victoria Land in the Antarctic : 8. armata Chevreux from the Gulf of Gascony and the Azores. The remaining species, S. innominata Bate was recorded from the Gulf of Naples, but is still imperfectly known. LEUCOTHOE SPINICARPA, (Abildg.). Leucothoe spinicarpa, Stebbing, 1906, p. 165.

One specimen, male, about 6 mm. long, exact locality not recorded. Distribution. Australia, New Zealand, South Orkneys. As this species is as yet only imperfectly known and belongs to a peculiar genus, the following description of the single specimen obtained by the "Endeavour" may be acceptable. The general shape of the body agrees with Haswell 's description, and is shown in Fig. 7 a; the back is smooth; the side plates are all shallow and present no peculiarity. The antennae (Fig. 7 b) are stout, pediform, the fiagel- lum being vestigial in both. The first antenna has the first joint about the same length as the second, both end in sub- acute teeth and sharp spines above and below, and bear a row of spinnles on the under surface, in the first segment the under surface being concave with spines along both margins; the third joint is considerably shorter than the second, but ends similarly with spines. The flagellum is represented only by one or two minute joints, the first one being produced to an acute point reaching to the end of the A M Pill POD A. OITILTON Fig. 7 " ft.

The first gnathopod (Fig. 7 d) is very small, long, slender ami delicate, and ends without dactyl in a small tuft of setae as in C. pusilla (Grube). The second gnathopoda (Fig. 7 e) are large and power- ful, the right and left equal in sixe. The basal and ischial joints are produced into a flange on the inner side against which the large propod rests when renexed. The carpus is short and subtri angular and bears on the posterior margin several transverse rows of long setules, a similar row extend- ing along the distal margin on the inner side. The propod is greatly dilated, being fully two-thirds as broad as long; it bears numerous transverse rows of setae near the anterior margin, others along the posterior margin and numerous single setae scattered at various places on the inner sur- face; the palm is denned by a stout subacute tooth, is broad, and shows two or more rounded prominences; the finger is short, stout, strongly curved, and fits into a depression near the defining tooth. The peraeopoda call for no special remark, the third, fourth and fifth have the basal joint only slightly dilated. (S<-e Figs. 7 /' and Q.) . Fig, 7 / /(. Colomastix In'azieri, Haswell, male. /.

The first and second uropoda are small and have the rami small, styliform and subequal, both finely serrate on the upper margin. In the third uropod the outer ramus is small, slender and shorter than the peduncle: the inner ramus is much longer, three times as long- as the peduncle, flattened vertically, the upper margin serrate or irregu- larly dentate. (Fig. 7 fe). The telson reaches beyond the end of the peduncle of the third uropod. Colour. In spirit, dull white, eye red, green according to Stebbing. The single New Zealand specimen that I have is much smaller, and is probably immature. It was obtained by surface net in Port Chalmers in 1904; it is still greenish in colour (mounted in glycerine jelly) and when alive the eye was a bright red. The second gnathopod is small and appears like that of. C. pusilla as figured by Bonnier (1893, pi. 8), who says his figure is that of an adult male, though judging from the "Endea- vour" specimen it seems possible that his were not fully developed. In the third uropod the outer ramus is much shorter than the inner. In the "Scotia" specimens from South Orkneys the outer ramus was two-thirds the length of the inner. Probably as the animal develops the inner ramus becomes longer in proportion. LlLJEBORGIA BREVICORNIS, (BrilZ.) . Liljeborgia brevicornis, Stebbing, 1906, p. 231.

These specimens are certainly similar to those described by Stebbing under the name L. aequabilis, agreeing in the absence of dorsal dentation, but the species is, I think, too close to L. brevicornis Bruz. to be retained as a separate species. Stebbing mentions several small points of differ- ence, and of these the first one, namely, the absence of a projecting tooth at the lower bind corner of the first and AMPHIPODA. CHILTON. <>?> second side plates holds good in the specimen I have specially examined, but these teeth are so small in L. brevi- cornis that their absence is not a very important character. The third pleon segment has the lateral margin straight and shows no emargination above the postero-lateral tooth; the slender finger of the fifth pair of peraeopods is not more than one-third the length of the propod. and is thus similar to the figure given by Sars : the length of this finger appears to vary, being longer in smaller specimens ; the telson has only a single seta in the notch at the end of each lobe, thus agreeing with Sars' figure and differing from Stebbing 's description. The slight differences mentioned by Stebbing in the gnathopods appear of little importance, those of my specimen agreeing quite closely with the figures given by Sars, the palm of the second having a small con- cave depression near the base of the finger. L. brevicornis Bruz. is known from the Arctic Ocean and the North Atlantic. If L. aeqitabilis is really the same its range is extended to Australian seas. The species L. proximo, Chevreux from the Gambier Archipelago should, in Mr. Barnard's opinion, become a synonym of L. aeqnabilis. He records it from False Bay, South Africa.

Two specimens, the largest 15 mm. long. (Reg. No. E. 5352.) These specimens agree on the whole with the description of this species given by Stebbing in 1906. The sixth and seventh segments of the peraeon are produced into a sharp dorsal tooth and there is a minute tooth on the fifth seg- ment also ; the teeth and carinations on the pleon are as described by Stebbing. L. dubia is known from Australia, New Zealand, South Africa, the South Orkneys, and South Victoria Land. The closely allied species L. consanguinea has been recorded by Stebbing from Kerguelen and Heard Islands and by Chev- reux from Marguerite Bay in the Antarctic. The two species present many points in common which are also found in the European species L. /is.vicoriiix (Sars.) fiH "ENDEAVOUR" SCIENTIFIC RESULTS, OEDICEROIDES ORNATUS, (Stebbiwj).

This specimen agrees with 0. ornatus in the shape of the eyes, which extend to the acute tip of the frontal process, and in the little process to which the ventral carina of the rostrum is produced. It was obtained in Bass Strait near where the typical species was collected. The segments of the body bear rounded corrugations, but there is an absence of the small tubercles which appear to be so marked in Stebbing 7 s figure, the species in this respect being more similar to 0. Cinderella from the Falkland Islands. How- ever, the resemblance in the eyes and in the appendages is, I think, sufficient to warrant its being assigned to 0. ornatus. The species was taken by the "Thetis" off Port Hacking and also from Botany Bay, New South Wales. BOVAT.LIA MONOCULOIDES, (Hdswell) . Eovallia Moiioculo-idrs. Chillon, 1909, p. 622, and 1912. p. 494.

Under the name Bovallia monoculoides or Eiisiroides monoculoides a number of forms have been grouped, the relations of which are rather puzzling. In the "Challen- ger" Report, Stebbing described three species under the new genus Eusiroides, namely, E. caesaris, E. pompeii, and E. crassi. In "Das Tierreich" Amphipoda he united the first two as synonyms of the previously described species AMPHIPODA. CHILTON. <>7 Atylu* monoculoides Haswell, but left K. crassi as a dis- tinct species. In 1909 I identified specimens from the Auckland Islands with E. crassi and gave various reasons for the opinion that it could hardly be kept as a species distinct from E. monoculoides (i.e., E. caesaris and E. /tonrpeii). I also pointed out that my specimens appeared to be nearly identical with Bovallia, yiyantea as described by Pfeffer and Chevreux. In 1912, after comparing speci- mens gathered by the "Scotia" with co-types of BovdUni yiyantea, I remained still of -the same opinion. In 1913, p. 168, Chevreux advanced several reasons for considering ft ova-Ilia yiyantea distinct from B. monoculoides. In draw- ing up these differences he has, I think, based some of them on the published descriptions of K. caesaris. It has been pointed out by Walker. Stebbing and myself that in B. monoculoides there are very considerable variations in the presence and acuteness of the dorsal teeth and in the amount of serration of the posterior margin of the third pleon segment. Certainly extreme forms of E. monoculoides (i.e., E. caesaris} and B. yigantea look considerably different, but if we are to unite under one species E. caesaris, E. pompeii and E. monoculoides, then the differ- ences between these forms and Bovallia yiyantea do not seem to me to be sufficient to warrant us in keeping them distinct from that species. Whether the different forms are to be distinguished by different names or not is a point of comparatively little importance, the main point is to ascertain the characters of the forms under consideration and the amount of variation they show. This will be illus- trated by the following brief description of the specimens gathered by the ' ' Endeavour. ' ' Off the Tasmaiiian Coast, four specimens (Reg. No. E. 5352) were collected. One of these is a female fully 20 mm. long with recently hatched young in the brood pouch. Both upper and lower antennae agree well with the figures given by Stebbing for E. caesaris and also with those given by Chevreux for Bovallia yiyantea, except that the calceoli are not so numerous on the peduncular joints. The third pleon segment has the posterior margin convex and without serrations, the angle being very slightly pro- duced, in this respect agreeing with both E. crassi and B. yiyantea. None of the segments are produced dorsally into teeth ; the fourth pleon segment shows a depression, more distinctly marked than in Stebbing 's figure; the fifth segment is produced posteriorly into a short median tri- angular tooth, which in side view appears as a narrow 68 {C ENDEAVOUR" SCIENTIFIC RESULTS. curved tooth. In the absence of dorsal teeth and of serra- tions on the third pleon segment this specimen agrees with /". r>v/.v.v/. A second specimen, about 15 mm. long, a female bearing eggs, is similar in general appearance and in the appendages, bul lias the posterior margin of the third pleon "-"ument with numerous dentations as drawn by Stebbing for E. ponipfii, there is a very slight indication of pleon segments one and two being produced into dorsal teeth, but no sign of a tooth on pleon segment four, the presence of which in the previous specimen seems to be exceptional. The third specimen, also a female with eggs, about 13 mm. lonu 1 , has the first and second pleon segments very slightly produced, and is similar to the second in practically all other characters, but the third pleon segment has more numerous serrations, these being nearly as numerous as shown by Stebbinir for E. caesaris. The fourth speeimeri. about 12 mm. long, also a female, is similar to the second and third but has only about six or seven serrations on the third pleon segment, the rest of the margin being slightly uneven. Oft Kingston, South Australia, two specimens (Reg. No. E. 4862") were collected, each about 15 mm. long, and havina 1 the serrations on the third pleon segment intermediate in character between those shown for E. caesaris and E. ponipeii by Stebbing. One of them also showed very slight dorsal production of pleon segments one and two. Certainly all the "species" mentioned above must, in my opinion, be placed in one genus, and the name Bovallia appears to have priority over Eusiroides. PARAMOERA AUSTRINA, (Bate) var.

Further discussion of the various forms is given by Barnard (1916, p. 183), who includes Atyloides tuayellanica Stebbing (1888, p. 925, pi. 79) as a synonym of P. ca pens is (Dana). The "Endeavour" specimens all appear to belong to the variety megalophthalma, which may be distinguished by the very large eyes, the presence of a distinct rostrum (Fig. 8 a), the shorter and more triangular carpal joints of the gnathopoda (Fig. 8 6), the broader rami of the third nropods and the absence of setae from the telson (Fig. 8 c) . The accessory nagellum seems to vary, as might be ex- pected. In the specimens from Port Jackson that I have examined it is almost indistinguishable and apparently fused to the last joint of the peduncle; in the "Endeavour" specimens it is fairly distinct as in typical specimens of the species. Stebbing considers Atylus microdeuteropus Haswell from Port Jackson to be a synonym of Amphitoe (Iphimedia] simplex Dana from Hermit Island, and says that the species is probably identical with P. austrina Bate. There is very considerable resemblance between the descriptions and figures given by Dana and Haswell, and it is probable they were describing the same species, but the enlargement of the joints of the nagellum of the first antenna mentioned and figured by each seems to me to be too marked and too widely separated "every third or fourth" (Haswell) to apply to P. austrina, in which every second joint is dilated but only to a slight extent, and' the species more probably belongs to the genus Pontogeneia.

This widespread species appears to be fairly common in Australian seas.

The fifth peraeo- pod (Fig. 10 c d) is broad, especially in the meral joint -. the posterior margin of the basal joint is moderately convex and simply serrate on the proximal portion, while on the distal portion the serra- tions are much closer and deeper, forming a regular pectinate margin, similar to that in E. neglectus, Ohil- ton, and E. serrula.

The species is common on the Australian and New Zealand coasts and is also known from several localities in ll'.e Indian Ocean. AMPHIPODA. CIIILTON. 77 POLYCHERIA ANTARCTICA (tit-ebbing). Polycheria aiitlnliti-anthus (Stebbing). First gnathopod of male. In the female (Fig. 11 r) and in the immature males appendages are not so elongated and correspond more nearly to the figures given by Stebbing of the "Challenger" specimens (1888, pi. 110). ' It will be seen from the figure of the adult male (Fig. 11 a) that in this character L. philacanthus presents very considerable resemblance to L. longipes (Liljeborg) and L. web'ster i (Spence Bate) from the Northern Hemisphere. In these species, however, the arrangement of the long slender setae on the first gnathopod is slightly different. In 1914 Stebbing redescribed L. fueyiensis (Dana) from specimens obtained from the Falkland Islands and identified with that species the form from the Indian Ocean described under the name of L. kergueleni by Walker in 1909. From the description and figures given by Stebbing it is evident that L. fuegiensis approaches very closely to L. phil(ic. Second gnathopod of one side. The male differs from the female in the second gnathopod which agrees with the description given by Stebbing. In this specimen, as in the "Thetis" specimen examined by Stebbing, the second gnathopods were unequal, one of them resembling the female form. In a recent paper (1920, p. 8) I suggested that Eurystheus thomsoni (Stebbing) was somewhat similar to E. dentatus, Chevreux, which I had recorded from New Zealand waters, and the females are certainly somewhat difficult to distinguish ; but the male of E. thomsoni, which I have now for the first time been AMPHIPODA. CHILTON. 83 able to examine, differs considerably and is not very dis similar in the second gnathopod from E. crassipes (Haswell), though the fourth peraeopod does not appear to be greatly broadened as in that species.

I give figures of the first gnathopod (Fig. 13 a) and of the right (Fig. 13 &) and left (Fig. 13 r) second gnathopoda of the male specimen.

Eyes large, reddish, oval, in horizontal direction, situated on the narrow rounded lateral lobe of the head below the insertion of the upper .antenna. All the appendages very hirsute, a pair of tufts of setae on the dorsal surface of the fourth and fifth segments of pleon. Side plates small, shallow. Upper antennae (Fig. 13 a) with first joint shorter and stouter than second and third, which are subequal, flagellum of about 20 joints, rather long-er than the last ^egment of peduncle- accessory fiagellum 5-6 jointed. Lower antenna (Fig. 1.3 a} with last two segments of peduncle subequal in length and about as long as the second of the upper; fiagellum of 1(1 joints nearly as long as last joint of peduncle. Both antennae are densely fringed with long setules. Fig. 14 a b. Eiirystheus persetosus, sp. nov. a. Head and antennae, b. Terminal portion of pleon with uropods and telson. AMPHIPODA. C HILTON. 85 The first gnathopod with merus ending acutely at the distal angle; carpus slightly shorter than the propod, posterior margin somewhat lobed and bearing 6 or 7 tufts of long setules; anterior margin with a row of six short, stout setules; propod oval, narrowing distal! y, palm very oblique, slightly concave, defined by a blunt tooth and having an acute tooth about the centre; finger with inner margin serrate. The second gnathopod similar to the first but with carpus shorter, propod rather longer and palm more distinctly concave, with the central tooth small. Basal joints of the third to fifth peraeopoda rather narrow, posterior margin in the fifth straight. Third uropoda with rami subequal. Telson with dorsal surface depressed in the median line, raised on each side into narrow rounded lobe, tipped posteriorly with a stout setule (Fig. 13 &). Length. About 12 mm. Colo ur. Brownish. The mouth parts are normal and agree well with those of the genus, the inner lobe of the first maxilla well developed and bearing numerous long setules. I am very uncertain about the position of this species, of which I have seen females only. In the hirsute character of the appendages, the gnathopods and some other points, it agrees with the description given by Stebbing (1906, p. 615) of Eurystheus hirsutus (Giles), but that species is considered by Walker to be the female of Cheiriphotis megacheles (Giles) which differs in the very small size of the inner ramus of the third uropod and in other respects. AMPITHOE FLJNDERSI, Stebbing. (Fig. 15 a-d.) Ampithoe flindersi, Stebbing, 1906, p. 635, and 1910, p. 616. Locality. 40 miles west of Kingston, S'outh Australia, 30 fathoms. One female (Reg. No. E. 4862). I think this must be referred to Stebbing 's species, although in the absence of male specimens the determina- tion of the species of this genus is very uncertain. Stebbing 's description was based on a single specimen 'ENDEAVOUR SCIENTIFIC RESULTS. d Fig. 15 a, b and d. Ampithoe Ji.indersi, Stebbing, female. . First antenna, b. Second antenna, d. Second gnathopod. about 4 min. long, in which the antennae were wanting and which, as he suggests, was probably an immature specimen. The further specimens from the "Thetis" Expedition examined by him also lacked the antennae Of these speci- mens he described the second gnathopods as having "an AMPHIPODA. CHILTON. 87 excavation of the palm at right angles to the hind margin of the sixth joint," and as this seems to agree with the "Endeavour" specimens I venture to make the identifica- tion. In order to complete the description I give figures of the peduncles of the antennae (Fig. 15 a and &) and of the gnathopods (Fig. 15 c and d) from which the .structure can be learnt without further detailed description. I have some specimens of an Ampithoe from Norfolk Island which I had previously thought probably belonged to A. flindersi, but in them the carpus of the first gnathopod is very much longer than in the present specimen, being longer than the propod, and possibly the Norfolk Island specimens should be placed in a separate species. The "Challenger" specimens were from Flinders Passage in Torres Strait, and those of the "Thetis" from off Wata Mooli. N.S.W. Fig. 15 c. Ampithoe jiindersi, Stebbing, female. First gnathopod. "ENDEAVOUR" SCIENTIFIC RESULTS. ICILJUS AUSTRALIS, HttSWfll. (Fig. 16 a-c.) Icilius ovalis (part), S'tebbing, 1906, p. 706. Icilius australis, Stebbing, 1910, p. 628. Localities. 40 miles west of Kingston, South Australia, 30 fathoms, several specimens; Sanders Bank. Kangaroo Island, South Australia, 28 fathoms, two specimens; Shoal- haven Bight, New South Wales, several specimens, 15 miles N.W. Cape Jervis, South Australia, 17 fathoms, one specimen. I think all these specimens must be referred to Icilius australis, Haswell, as defined by Stebbing in 1910. He had previously considered all the species of Icilius to be synonyms of Icilius ovalis, Dana, but in 1910 prefers to recognise the four species as distinct. He divides them into two groups, the first containing 7. ovalis, Dana, and 7. danae, Stebbing, having the pleon segments produced dorsally into a median tooth; the second containing 7. australis, Haswell, and 7. punctatus, Haswell, with the pleon segments not produced. The "Endeavour" speci- mens come under the second group and, on the whole, agree fairly well with Stebbing 's description and with specimens named 7. australis, Haswell, sent tame from the Australian Museum. In one or two points, however, they seem to come a little nearer to 7. punctatus, Haswell, and I should not be surprised if these two species have to be again recombined. In the fifth peraeopod the shape of the basal joint (Fig. 16 a) is pretty much the same as that shown in Stebbing 's figure, having a narrow bulge at the top, though the difference between this and the corresponding part of 7. punctatus seems to be slight. I am giving a drawing of the third uropod (Fig. 16 c) showing the inner branch which was wanting in Stebbing 's specimen. This shows that the inner branch is almost identical with that drawn for 7. punctatus by Stebbing, but that the outer branch is longer and has more setae on the lateral margin, thus agreeing with the description of this joint for /. australis. The drawing is made from a specimen taken off Kingston, South Australia, but in specimens sent from the Australian Museum the outer branch of the third uropod is shorter and has only one or two setules on the outer margin, being thus intermediate in character and approaching that of 7. punctatus as drawn by Stebbing.

They are not quite so broad as drawn by Stebbing for /. australis and have the inner margin straight with only a slight indication of the lobe near the base and the spinules on the outer margin are fewer than shown in Stebbing 's figure. 90 ' ' ENDEAVi iTR " SCIENTIFIC RESULTS.

THIS report includes all the bracliyuran crabs of the "Endeavour" collection other than the Oxyrhyncha or spider crabs, which were enumerated in Vol. V., part 1, 1918, with one exception here noted. There are sixty-one species listed below, and fourteen of these are new. There are also, among the species previously known, several which are additional to the Australian fauna: Pinnotheres novcezelandice, Pilumnoplax heterochir, Liagore rubromacu- lata, Chlorodopsis pilumnoides, Pilumnus spongiosus, Acanthodes arm at us, Charybdis natator, C. truncata, Myra fngax, Calappa Jophos and Dromidiopsis edwardsi. The most noteworthy is Acanthodes armatus, which, although described by de Haan in 1835, has been found rarely, and then only in Japanese waters. I am indebted to Mr. Allan R. McCulloch for allowing me to introduce some of his notes, made several years ago, and for making it possible to examine several Australian Pilumnus not in the "Endeavour" collection. Order DECAPODA.

The first three pairs of ambulatory legs are longer than the chelipeds. This species was accidentally omitted from the report on spider crabs, vol. v., part 1, of this series, on account of its strong resemblance to Telmessus, save for the arrange- ment of the basal antennal segment.

Legs similar, dactyli curved; second pair longest, its dactylus also longest ; the first and third legs are subequal, the fourth shortest. The left leg of the second pair is longer than the right ; whether this is individual or a specific character as in certain American species, only an examination of further material can determine. The abdomen is very capacious, wider than the widest part of the carapace and envelops the sternum and bases of the legs.

On the upper border of the arm distad of the middle there is a rounded lobe ; dorsal aspect of wrist an elongated rhomb, with a spine at the inner angle, and a smaller one at the outer angle. In the male the dark brown colour of the immovable finger embraces a small part of the palm except in its upper part where it does not quite cover the pre- hensile edge; on the dactylus the colour does not quite cover the proximal end but seems to cover the prehensile edges when the fingers are closed. In the female the brown is much more restricted, extending on the outside edges less than half the length from the tip in the full-grown, or quite half the length of the dactylus in the half -grown ; on the prehensile edges the colour runs much further, half or more than halfway on the immovable finger, and nearly the whole length on the minor dactylus and quite the whole length on the major dactylus. Ambulatory legs long and slender; last three articles sparsely fringed with long, fine hair ; the dactyli have also two marginal stripes of dense pubescence. The male abdomen is nearly triangular from the third segment to the tip, posterior margin of terminal segment arcuate. The sternal furrow just in front of the bases of the chelipeds forms a slightly obtuse angle at the median line. CARCINOPLAX VICTORIENSIS, sp. nov. (Plate xix.) Type-locality.

Of similar appearance to the preceding and at a glance might be mistaken for it. The chief differences are: The antero-lateral angle of the carapace is coincident with the outer angle of the orbit, instead of being advanced beyond the orbital angle to form a tooth. The first of the marginal teeth is less dentiform, its sides at an oblique angle to each other, meeting in a short, acute tip. The spine at the lateral angle of the carapace is directed more outw r ard. The supra-orbital fissure is more deeply marked. The wrist is squarer, less elongate. The proximal end of the palm, opposite the carpal spine is produced in a tubercle. The fingers are longer, slenderer and bent downward beyond the lower border of the palm. In preserved speci- mens they are almost colourless; only on the teeth of the distal third to half is there trace of a violet brown. The dactyli of the ambulatory legs are almost covered with dense pubescence; a thinner coating of similar hairs runs along the greater part of the upper margin of the propodal segments and a short way on the lower margin.

The chelipeds become very massive with age; the largest male (E.4779) lacks the major cheliped but the minor one is much larger than in the type specimen which has a somewhat smaller body. The fingers of the females (there are none of large size in the collection) are little deflexed. A young female (E.6091), 8.7 mm. long, has the first antero-lateral projection spiniform or tipped with a slender spine so that it has a strong resemblance to the spine at the lateral angle; the granulation of the hands is more pro- nounced than in the old. BRACHYURA. RATHBUN. 103 The four young crabs registered E.5196, probably repre- sent one of the earliest stages of the crab-form. The cara- pace is very narrow, as may be seen from the measure- ments, and subquadrate, the sides being parallel except just behind the orbit ; the two lateral spines are nearly the same size and shape. The granules of the palm are arranged partly in longitudinal rows and mixed with fine hair. Family XANTHID^E. Subfamily XANTHIN^E. XANTHO BOWENENSIS, sp. nov. (Plate xx.) Type-locality. S'even miles north-north-east of Bowen, Queensland, 16 fathoms; E.3097; one male, holotype. Measurements. Male holotype, total length of carapace 31, greatest width, at last pair of lobes, 46.3, fronto-orbital width 17.6, front 10 mm. Description. Carapace very convex fore and aft, closely covered with uneven granules, which are smaller in the depressions ; anterior two-thirds well areolated, areoles 1 L and 2 L fused, 1 and with 3 L and 4 L high and Act&a-like 5 L and 6 L lower and partially fused ; a small, transverse, oval areole on the posterior cardiac region ; anterior mesogastrium very narrow; protogastric regions unevenly and incompletely divided ; epigastric lobes distinct. Of the four lateral lobes, E is very low, N and T are obtuse-angled, S is rounded. Front not visible in dorsal view; median fissure closed, its sides overlapping ; on each side a truncate lobe occupies! less than half the front ; a broad, shallow sinus separates it from the pointed outer tooth; no supra- orbital angle. Suborbital region, reaching to a line from the buccal angle to lateral tooth N, roughly granulous like the dorsum. The fissures either side of N are continued on the lower surface where they almost meet in a small, circular depression. Chelipeds equal in male, closely granulous, the granules smaller and smoother on the merus than on the carpus and propoclus; carpus slightly furrowed; chelae short, stout, tapering distally ; fingers black, fluted, with blunt tips, and meeting when closed. 1 See Dana Crust. U.S. Expl. Expecl., part i., 1852, p. 29. 104 " ENDEAVOUR SCIENTIFIC RESULTS. Legs granulous, the three principal segments short and broad ; dactyli hairy between the granules. Remarks. This is not a typical Xantho in all respects, it is too convex at its middle, and the front too deflexed, and uncommonly narrow. On the other hand, the orbits and antennae are typical, the flagellum not excluded from the orbit. PSEUDOCARCINUS GiGAg (Lamarck) . Cancer gigas, Lamarck, Hist. Anim. sans Vert, v., 1818, p. 272.

Southern Australia; one immature female. A series of eight specimens, the three largest of which are 140 mm. wide or a little smaller, and the remainder graduated down to one 12.3 mm. wide. In small specimens the carapace is roughly granular except in the furrows; the granules on the inner and outer surfaces of the hand tend to form more or less distinct rows. All the spines on the carapace and legs are much more acute than in larger examples; in carapaces under 40 mm. wide, four of the lateral spines are much more developed than the inter- mediate ones, and the third and fourth large spines, or those near the widest part of the carapace are longest. The teeth on both fingers are proportionately larger. The chelipeds are subequal in size though the right is the larger. BRACHTDRA. - RATHBUN. 105 As the specimens increase in size, all these characters become less marked except the size of the hand, the right becoming gradually larger than the left. The red colour of the back may be uniform, as described by McCoy, or divided up into different patterns in different specimens. It may form vermiculating lines on the yellow ground colour or the latter may break through it as irregularly shaped spots. The chelipeds are all marked with vermicular red lines, and the fingers are uniformly scarlet at their junction with the hand. 2 LlAGORE RUBROMACULATA, de Liagore nibromaculata, Alcock, Journ. Asiat.

Male holotype, length of carapace 5.1, width of same 7.7, fronto-orbital width 4 mm. Description. Carapace, chelipeds and legs furnished with scanty hairs which do not conceal the surface and are scarcely to be noticed. Carapace covered everywhere except on the cardiac and intestinal regions with fine, sub- equal granules; well, but not deeply areolated; areolations but not granulations visible to the unaided eye. Each protogastric region is divided by a shallow, longitudinal sulcus which fades out posteriorly, into two unequal parts, the inner part half as wide as the outer; epigastric and autero-exterual protogastric lobes swollen. In the language of Dana, 3 lobes 1 L and 2 L are scarcely separate, 3 L and 4 L are well marked, 5 L shows a tendency to subdivide, 6 L is faintly outlined behind, 1 R, 2 R and 3 R are con- tinuous. Of the marginal lobes, N, T and S are prominent and somewhat angled, E is nearly flat. Postero-lateral margin concave ; above the posterior margin there is a narrow, raised, bilobed and crenulated ridge. Frontal lobes in front view with sinuous margins separated by a median fissure; at the outer ends an independent, triangular tooth bent downward. Chelipeds of immature male small; carpus granulous like the carapace, and with a few shallow furrows. Granules of palm arranged largely in longitudinal rows especially on the lower half of the outer surface ; immovable fingers with two outer furrows, the lower one leading from the palm and tapering to a point, the upper one reaching only to middle of finger, a tooth on prehensile edge near its base; dactylus with a deep groove below the upper margin, a small tooth near the base of that margin, a large basal tooth or tubercle on the prehensile margin and a shallow tooth further out and distad to that on the immovable finger. Legs granulous, except on the posterior surface of the merus joints, the granules more pointed than on carapace. Dana Crust. U.S. Expl. Exped., parti., 1852, p. 29. BRACHYORA.

Meth., Entom., x., 1825, p. 125) compares lanatus with vespertilio, as follows : " Un pen, plus grand que le precedent, avec les set-res e"paisses et g raveleuses ; d'ailleurs presque semblable. Vari6t6 peu,t-3tre du male de cette espece." This indicates a much closer re- semblance of lanatus to vespertilio than one would ascribe to the trim looking species figured by Miers, Inc. cit. I have, therefore, used the name Innnilis for his species. 110 "ENDEAVOUR" SCIENTIFIC RESULTS. g. Two notches in upper margin of orbit. A sub- hepatic tooth present.

South of Gabo Island, Victoria, 200 fathoms; E.6212; one male. Carapace length 5.6 mm., width 7.1 mm. This specimen is much smaller than those described by Nobili; the carapace is proportionally narrower than that of the female measured by him, the distance being shorter from the orbit to the second of the five lateral teeth. In nearly every respect the "Endeavour" specimen agrees with the descriptions cited; there is, however, indication of a transverse fringe of hair on the front, though it is incomplete ; the pubescence in front of the fringe is shorter than behind it ; only one row of granules is discernible on the margin. It may be added that both fingers of both chelae are deeply grooved, and the granulation extends half the length of the dactyls and almost to the tips of the immovable fingers. 112 "ENDEAVOUR" SCIENTIFIC RESULTS. PlLUMNUS DIGITA1/IS, Sp. 710-1'. 6 (Plate xxii.) Type-locality. South 29 east of Pine Peak, Queens- land; E.6486; one male, holotype. Length of carapace 9, width 12, width of front 4.8, distance between outer angles of orbits 9, length of penultimate leg 16.8 mm. Additional locality. Eleven to fourteen miles north- west of Pine Peak, Queensland, 24-26 fathoms; E.3188; one male. This species belongs to the group of P. trichophofus 7 de Man, P. trichophoroides* de Man and P. Iborradailei^ Rath- bun. Like them it has the posterior half of the carapace flat, the surface of body and legs almost entirely covered with a coat of short hair, while fringes of long hair ornament the anterior third of the carapace, and also the chelipeds and legs. The new species has a narrower cara- pace, its length just three-fourths of its width ; the fronto- orbital distance is greater in proportion to width of cara- pace ; the regions are mostly well defined, the mesogastric, protogastric, frontal, cardiac, anterior branchial and posterior branchial ; while a furrow sets off the narrow marginal rim of the front, the wider, inner margin of the orbit, the posterior margin, and partially circumscribes an inner branchial areole. The outer of the two emargina- tions of the upper orbital margin is much the larger and helps to define the dentiform outer angle, which is more acute than the three succeeding blunt teeth of the aiitero- lateral margin of the carapace. The transversely oblique ridge leading inward and forward from near the hinder part of the posterior tooth is pronounced and granulate. A similar ridge is subparallel to the antero-lateral margin, and runs from the gastric region to a point opposite the third tooth. c It should be noted that, in drawing the different species of Pihimnus, the carapace has been inclined so as to represent the true edge of the front, even though that edge is invisible in a strictly dorsal view. 7 de Man Zool.

Male holotype, total length of carapace 11.6, total width 13.5, fronto-orbital width 9.4, width of front 5 mm. Description. A narrow species without spines, clothed with uneven, ragged-looking hairs. Carapace covered with short and rather fine hair, also long, coarse hair disposed in a line behind the front, a bunch on each protogastric region and a larger patch near the margin at the widest part of the carapace. "When, the hair is removed, the hepatic region is seen to be marked off by a wide furrow, the epigastric regions are isolated, the protogastric regions are continuous with the broad part of the mesogastric region, the median furrow, including the narrow part of the mesogastric region, is deep, the epibranchial lobe is raised, the lateral teeth are separated off in a sort of rim. All the most elevated parts of the carapace including the frontal, epigastric, middle part of protogastric, hepatic and epibranchial lobes, also the antero-lateral teeth and the postero-lateral regions are granulate. The large lobes of the front are broadly rounded, median notch of good size, lateral notches larger, the outer teeth slightly acute. Inner upper angle of orbit almost obsolete. Margins of front and orbit granulate, one well-marked superior orbital notch, a shallow notch below outer angle, a thick, triangular tooth at lower, inner angle. Suborbital and subhepatic regions very finely granulate ; 110 sub- hepatic tooth nor spine. Four antero-lateral teeth, the first low, second largest, carapace equally wide at the third and the fourth tooth. 114 " ENDEAVOUR " SCIENTIFIC RESULTS. Chelipeds and legs clothed with long hair, through which the surface is imperfectly seen ; arm with a large, subterminal tooth above, lower and inner margins tuber- culated ; carpus finely and sparingly granulate, a small tooth at inner angle ; larger palm unevenly tuberculate, the tubercles largest on upper surface and on lower, distal portion of outer surface; proximal half of lower margin tuberculate ; fingers smooth except upper, proximal end of dactylus ; two grooves on outer surface of fixed finger, which is slightly deflexed. Minor palm considerably smaller, tuberculation continued so as to embrace the w r hole lower surface, and part of the fingers, each finger -with three deep grooves on the exposed surfaces. Legs almost entire, the upper margin of the merus finely and obscurely roughened. Remarks. In shape this resembles some species of Heter&panope Stimpson. :o Of the species of Pilummis, it has much in common with P. marginal us Stinipson 11 from Loo Choo, but the carapace of the latter is wider with more convergent postero-lateral borders and the hands are more finely roughened. In P. contrarius the tubercles of the major palm, con- trary to the customary rule, increase, instead of diminish, in size toward the distal, lower portion, a fact to which the name draws attention.

The species may be recognised by its ragged appearance, the carapace more than half smooth and naked, the long, coarse, tubular hairs disposed in tufts on the anterior and antero-lateral portions; besides there is a small tuft above each posterior corner, and a still smaller tuft at each end of the gastro-cardiac suture. The granules and tubercles on the hepatic region are partially exposed. The upper part of wrist and hand is almost bare and armed with large tubercles; the distal half of the larger palm is also bare and the tubercles well spaced. The ambulatory legs are thickly clothed with hair on the upper margin, and in the last pair on the lower margin, while the posterior surface of the last two segments in all the legs is hairy.

Both females are smaller than the males, the smallest female (P. 3570) measuring 4.8 by 6.9 mm. A lot of four specimens from Port Jackson, sent to the U.S. National Museum (Cat. No. 17025) by the Australian Museum, run much larger, one male being 9.6 by 14.4 mm. or 1 :1.5. The width of the carapace, it will be seen, increases rapidly with age. In the "Endeavour" specimens the main pubescence is very short and close, but the tufts scattered about, especially on the elevations are formed of long, coarse but soft, tubular hairs, which are much longer than on the larger specimens; of a different sort are the long, slender hairs on the ambulatory legs and on the granulated portion of the chelipeds.

South 29 east of Pine Peak, Queensland; P.3573 ; four males, two females. Measurements. Male holotype, total length of carapace 7.3, width including teeth 10.2, fronto-orbital width 7.4, width of front 3.7 mm. Description. A small species. Carapace covered with short, dense pubescence and some longer, fine hairs. When the carapace is cleaned, it is seen to be well areolated; antero-lateral regions rough with four elevations, one hepatic, one extending inward and forward from the last tooth, two behind the orbit ; postero-lateral regions finely granulate. Frontal lobes almost free of pubescence, margins slightly oblique and granulate, median cut triangular; outer teeth independent, tuberculiform ; pre- orbital angle very obtuse and inconspicuous. Two well- marked emarginations in the upper, granulate border of the orbit ; a large, slightly acute tooth at outer angle, beneath which there is a narrow notch followed by a BRACHYCRA. RATHBUN. 117 denticulated margin which gradually advances to the acute inner angle. Three thick lateral teeth, more produced than the orbital tooth and each tipped with a small spine. No subhepatic projection, only a few granules. Posterior margin broad. Chelipeds very unequal, less hairy than carapace, pubescence not concealing roughness, large chela totally bare. Outer surface of merus granulate ; upper edge denti- culate, a large subterminal tooth, a smaller terminal one; inner edge tuberculate, lower edge partly so. Carpus covered with pointed tubercles, sharper and more spinelike on the smaller carpus, which also has a spine instead of a tubercle at the inner angle. Larger palm bare and smooth except for a band of tubercles or large .granules along the proximal end of the outer surface and a patch of the same at the proximal end of the upper surface. Two or three granules at base of dactylus. Fingers light brown, the colour covering the distal two-thirds of the fixed finger and almost the whole of the dactylus. The outer surface of the smaller palm is covered with pointed tubercles arranged in approximately seven rows, and a patch of the same is at the proximal end of the dactylus above. Ambulatory legs hairy, the merus roughened above by fine, unequal spinules. Relationships. The very unequal chelae suggest those of P. spinicarpus 12 but in that species the rough area on the larger palm is much greater, also the carapace and legs are longer. The carapace of tantnlus resembles in shape that of P. quadridentatus 13 de Man, which also has a striking inequality in chelae, but differs from tantulits in having five (instead of four) antero-lateral teeth, counting the post- orbital tooth, and in the larger palm being finely granulate outside.

Male holotype, entire length of carapace 12, width, including spines, 16.5, fronto-orbital width 10.5, width of front between antennal notches 5.5 mm. Description. Carapace very convex from front to back, suboval, the front little advanced beyond curve of antero- lateral margins, the latter nearly as long as the convex postero-lateral margins, posterior margin between legs of last pair arcuate. Posterior fourth or third of carapace smooth and bare; remainder covered with a thin coating of short, light-coloured hair, which does not disguise the surface. Regions fairly well outlined ; gastro-cardiac depression deep ; also the median furrow leading from the mesogastric region to the front. Surface roughened by two or three stout spinules on the hepatic region, by smaller spinules opposite the last lateral tooth, by the granuliform sockets of many of the surface hairs, and by fine, close granulation on the post-lateral regions. Edge of front invisible in dorsal view, median lobes deeply separated, oblique, extremities broadly rounded; small outer lobe dentiform with a tuberculiform tip. Supra-orbital border irregularly spinulose and granulose, inner angle not accented, notches obscure; outer angle or first antero-lateral tooth broad, tipped by a short, stout, curved spine, behind which is a spinule, and under which are several spinules -. a notch separates this tooth from the suborbital margin, armed with four or five stout spinules, and near the inner angle a broad tooth with bispinulose tip. The second, third and fourth antero-lateral teeth are similar to the first, but larger; the fourth has a narrower base than the second and third, and the spinule on its posterior slope may be absent, Submarginal regions granulose and spinulose, subhepatic region with three or more spinules, some of which are visible from above. Chelipeds of large male stout, unequal, but similar in shape and ornamentation ; merus very high, armed above with two large spine-pointed teeth, followed behind by obscure granulation on margin and on outer surface ; wrist and hand armed with stout, acute spines, which on the palm become lower and more and more tuberculiform toward the lower and distal margins until they altogether BRACHYURA.

Dorsal aspect of chelipeds hairy. In the female, the propodus has a straighter lower border, the small palm is rough all over the outer surface and half way down the fingers, the large palm is also rougher than in the male but finely so, and the spinulous area on the dactylus is longer. In the small male the armature of the lesser palm resembles that of the female. Merus of ambulatory legs subentire above; carpus and propodus armed with spines, carpus with about four, propodus about five. Remarks. The convexity of the carapace in connection with the complex lateral spines is sufficient to fix this species. PILUMNUS TOMENTOSUS, Latreille. (Plate xxvii., figs. 1-2.)

Description. Front advanced, antero-lateral margins arcuate, postero-lateral margins strongly convergent. Surface covered with short, numerous, but not crowded, single, yellow (in alcohol) hairs which entangle a coat of refuse; regions well marked, branchial region partially subdivided, several (three or four) subacute spines or spinules near the marginal spines. Front subtriangular, lobes with a short inner and lon.g outer slope and rounded tip, edge denticulate; outer tooth single, independent, triangular, spiniform. Inner angle of orbit suberect, not at all advanced. Upper orbital margin with a few spinules, two subequal emarginations, and an outer spine of moderate size. S'pinules of lower orbital margin larger and more regular than those of the upper margin, inner spine the largest. A narrow subhepatic spine is visible in dorsal view where it appears as a second antero-lateral spine; in side view it is in same straight line as three succeeding spines; these are large, sharp-pointed, conical spines, each with one or more spinules on its slope; the first of the three spines points almost directly forward. Chelipeds and legs clothed with similar hairs to those on the carapace, but on the legs the hairs are longer: on the chelipeds the hairs are thickest .i.bout the bases of the spines. Chelipeds very unequal ; merus with a terminal and a subterminal spine above, lower border obscurely denticulate, one or two spinules on inner border; carpus armed with scattered, conical, acute spines, the longest- one erect at inner angle. Larger palm covered with numerous, similar spines, pointing distad and sometimes especially in full grown males disappearing toward the lower margin and fixed finger; proximal end of lower margin tuberculate. Each finger has two outer, punctate orooves; the dactylus is tuberculate above at its base. Smaller palm similarly armed, usually all over the outside, 122 " ENDEAVOUR " SCIENTIFIC RESULTS. the spines showing signs of longitudinal arrangement and continued half way down the dactylus and nearly as far on the immovable finger. The ambulatory legs are rather broad, and little armed ; the merus has a terminal spinule on the upper border and a rightangled subterminal tooth. The very young have some long soft hairs among the short bristly ones. Remarks. P. tomentosus is by far the most abundant species of Pilumnus in the "Endeavour" collection. One would think from Miers 's figure, loc tit., that it was very smooth and trim looking, but it has a strong tendency to collect dirt and is very untidy looking. Some of the spines, especially those on the back, retain a red colour in alcohol. PILUMNUS HIRSUTUS, Stimpson. (Plate xxviii.) Pilumnus hirsutus, Stimpson, Proc, Acad. Nat.

There is also some variation in the convexity and in the advancement of the front. The larger female is the most convex, the smaller female has the least produced front, and appears to have (though really has not) the greatest relative fronto-orbital width. HRACHYDRA. RATHBUN. 123 The orbits are very wide, and the distance between the subequal, triangular, superior notches is uncommonly long. The four antero-lateral teeth are similar, having a triangular base and a very slender terminal spine which is shorter in the first or orbital tooth. In only the largest of the three specimens is there a subhepatic spine; it is very short, but visible in dorsal view. In the other two specimens there is on the subhepatic region a cluster of about three sharp granules, which is barely visible from above. The hair on the carapace is very soft and of two sorts, a short, fine fur, with small clusters of longer, coarser hairs, including a line just behind the frontal lobes. These lobes are broadly rounded, and are separated by a large notch; the outer tooth of the front is rather wide as these teeth go, sub- rectangular, and with a very small point ; the inner orbital angle is obtuse and inconspicuous. Upper margin of orbit and front finely granulated; lower margin with a definite outer notch, followed by a short granulate edge and then by sharp spinules mixed with granules. Chelipeds very unequal; merus with two spines at distal end followed by spinules ; wrists and palms armed with sharp tubercles or stout spines, which cover only half of the larger palm, and are seriate on the smaller palm. The brown colour of the fingers does not quite come to their bases. The larger thumb has a punctate groove not far above the margin; the dactylus is rough above near its base. Fingers of smaller chela deeply grooved, and roughened for half their length. PILUMNUS SPINICARPUS, Grant and McCulloch. Pilumnus spinicarpus, Grant and McCulloch, Proc. Linn.

Measurements. Male holotype, total length of carapace 15.4, width without spines, measured behind the last pair, 20.4 ; width with spines 22.3 mm. The gastric region and its three subdivisions are faintly outlined; a little deeper groove runs from the mesogastric region to the median sinus of the front. The dorsal surface of the carapace and appendages is covered with numerous hairs which are distinctly yellow in the specimens preserved in alcohol, and of different lengths, but on the whole rather long, and placed singly with few exceptions. The width of the front is less than half the length of the carapace; its large lobes are so denexed that they do not show in a dorsal view, they are subtriangular, ends broadly rounded, outer slope longer than inner, edge obscurely granulate, as is also the upper margin of the orbit. This shows two small, subequal, rounded sinuses, and at the outer angle a slender spine. At the inner suborbital angle there is a slender spine springing from a conical base ; on the lower margin there are also six or seven small spines or spinules, the outer of which is the largest and is separated by a V-shaped sinus from the exorbital spine. Suborbital region with one larger spine and one or two smaller spines and some spinules. Further back on the lateral border there are three slender horny spines set in larger, cylindrical sockets, from each of which spring behind the spine two or three hairs longer than the spine. The two spines near the distal end of the arm are similar to those bordering the carapace, and are succeeded by a few spinules; lower margin with a few small tubercles, BRACHYDRA.

The carpus is armed with long spines (right 14, left 12) one of which is erect at the inner angle. In the male the outer surface of the large hand may be divided somewhat obliquely into two unequal parts, the upper and larger part spinous and hairy, the lower part smooth and naked; the spines are arranged in six rows and those of large size number about twenty, but toward the distal and lower borders the spines diminish in size, becoming conical tubercles. A patch of hair and blunt, spinous tubercles at base of dactylus above. The rows of spines and tubercles cover the outside of the small hand and are arranged in seven rows, of which two rows are continued slightly on the fixed finger. In the female the larger hand is practically entirely covered outside with spines, which become smaller below. The merus joints of the ambulatory legs have a row of several curved spines on the upper edge, the carpus has three long spines above, except in the last pair, only two. Relationships. This species is near P. vestitus, Haswell, 15 having the same shaped carapace and front, a border of spines, a spine at either end of orbit, a similar arrangement of spines on chelipeds and ambulatory legs. It differs from vestitus in having the hairs arranged singly instead of in bunches, in the fainter areolation, narrower and more deeply separated frontal lobes, in the character of the lateral spines whose bases are cylindrical, not conical, in the spines of the wrist few and long instead of numerous and short, in the longer ambulatory legs, with one or two more spines on each merus and much longer spines on the carpal segments. The species also has a resemblance to P. terra-regina, 16 which has a granulate carapace, no spine outside the orbit, wrist rough with granules instead of spines, and unarmed legs. 10 Haswell Proc.

Carapace moderately convex from side to side, and not strikingly so from front to back ; covered with soft, uneven, and rather short hairs, which do not conceal the unevenness of the surface below ; interregional grooves deep ; gastric region divided into three ; two areoles on the anterior branchial region. Middle lobes of front oblique, separated by a deep, narrow notch, edge sparsely and minutely spinulous ; outer tooth triangular, tipped with a white spinule and separated by a right-angled sinus from the blunt, inner angle of the orbit. Upper margin of orbit hairy, feebly bi-emarginate, a small tooth tipped with a white spinule at outer angle; below this a broad V- sinus; lower margin sparsely spinulous; outer half transverse, inner half advancing gradually to the spine-pointed inner angle. A subhepatic spine a little longer than the outer orbital one. Behind it three conical, curved spines with sharp white tips. Chelipeds of female unequal, the left palm two-thirds as high as the right; the exposed surface is hairy, except on the fingers; nierus with two spines above, at, and near the distal end, upper and lower edges obscurely roughened, proximal end of inner margin as well as the inner margin of the ischium spinulous. The carpus and upper proximal half of the maims are armed with strong and rather sparse spines, which form the centres of clusters of hairs; on the carpus four or five of the spines run along the distal margin and the largest one is at the inner angle; on the lower, distal half of the manus the spines become smaller, more tuberculiform, and more numerous, reaching quite under the lower surface and part way on the immovable finger; this finger of the major chela is much broken, its lower line is continuous with the horizontal line of the palm until near the tip, which bends gradually upward ; the dactylus has a deep groove a little below and parallel to the upper margin, the basal two-fifths of its upper surface is spinulous. The immovable finger of the minor chela is slightly deflexed before it turns upward at the tip ; the spinulation and hairiness of the fingers are more extensive than in the larger chela. Ambulatory legs covered with hairs like those on the carapace and also long hairs w 7 hich are disposed chiefly along the margins. 128 " ENDEAVOUR " SCIENTIFIC RESULTS. ACANTHODES ARMATUS, de HttCin.

The smallest crab is very hairy and Pilumnus-like; hairs long and numerous, without concealing the surface. The hairs lessen with the growth of the animal, and in the larger male are rather scanty on the carapace. On the antero-lateral margin there are four long primary spines, the first of which is at the orbital angle ; in the interspaces are three .shorter spines, the first one a little below the marginal line. Above and subparallel to this row there is an irregular row of seven spines of which the first is near the orbit, the second is below the line, the fourth is largest, the seventh is opposite the post-lateral margin. In BEACHYURA. RATHBDN. 129 addition there are three spines in a triangle on the epibranchial region and two on the hepatic region. There are in all nine gastric spines, in transverse series: two on each epigastric lobe, and on each protogastric lobe, and in line with the latter, a small mesogastric spine. Frontal marginal spines six, the middle pair largest, the outer pair situated at the angle of the orbit; behind them there is a row of four spines. There are two supraorbital spines besides the three already mentioned ; suborbital spines five, the inner one much the longest, the others diminishing in size. Post-lateral regions rough with short spinules. A row of tubercles above the posterior margin. Chelipeds unequal in all the specimens, but not much so ; the armature is strong and similar. The spines of the legs are slenderer. In the three small specimens handled the spines retain about the same proportion to the size of the crab. In the type figured (about natural size) by de Haan, loc. cit., which is a female, not a male, as labelled, the spines of the appendages and of the margin of the carapace maintain about the same relative size as in the young, but the dorsal spines are reduced in size and the hairs of the carapace seem to have disappeared. Both chelte are spinous as in the young. In Doflein's figure (loc. cit.) which is of a much larger specimen, a male 15 cm. wide, all the spines are much reduced, some of them to spinules ; the major cheliped has increased enormously while the minor one has remained stationary; the major chela is nearly smooth. This species had not before been taken outside of Japanese waters. Subfamily EEIPHIIN^. TRAPEZIA CYMODOCE (Herbst). Cancer cynwdoce, Herbst, Naturg. Krabben u.

Off Point Inskip, Great Sandy Strait, Queensland, 10 fathoms ; E.3151 ; one ovigerous female, holotype. Measurements. Female holotype, total length of cara- pace 17.3, extreme width 26, width at base of spine at lateral angle 23, fronto-orbital width 18, width between orbits 10.2 mm. Description. Belongs to the subgenus Charybdis, in which the antennal flagellum is excluded from the orbit, the ridge that bounds the dorsum posteriorly forms a curve with the postero-lateral borders, the posterior border of the arm lacks a spine, and to that division of the subgenus in which there are no distinct ridges on the carapace behind the level of the last spine of the antero-lateral borders. 17 Incisus, cut ill to, referring to the cut into the first lateral tooth to form the second. 132 "ENDEAVOUR" SCIENTIFIC RESULTS. Three ridges present on carapace, one between the spines of the last pair, which is thrice interrupted, two gastric ridges, the posterior of which is interrupted at the middle, while the anterior one is broadly interrupted. Front cut into six rounded teeth, not including the inner supra- orbital angles ; the middle two are slightly more prominent than the next pair, which are wider and somewhat oblique on their inner slope ; outer pair least advanced, narrow and deeply separated from the second pair. Antero-lateral borders cut into six teeth, five of which are spiniform and similar, the sixth one a little longer. The second tooth is very small, dentiform, and is not salient beyond the outer slope of the first tooth, of which it seems to form an integral part. Orbit with a slight dorsal inclination; the major diameter is about two-fifths as wide as the inter- orbital distance ; inner end of lower margin in the form of a broad, blunt tooth. A granular ridge on lobule at outer angle of basal segment of antenna. Chelipeds of female stoutish, hairy on the depressed portions of the exposed surfaces. Three enlarged spines on anterior border of arm. Wrist with granular costae on upper and outer surfaces, the inner angle strongly spini- form, three spinules near outer angle. Hand Avith five granular costae, and on the upper surface five spines. Merus of last leg over twice as long as wide ; posterior border of propodus spinous. Relationships. The species looks much like C. spinifera (Miers) 18 , but the latter has a wider carapace, the median pair of frontal lobes are not narrower than the submedian pair, the second tooth of the antero-lateral margin is of greater size and prominence, and the carpus of the last pair of feet has a strong spine on its posterior margin 19 , and the propodus is unarmed.

The cardiac prominence is conical in the male, dome-shaped in the old female; the gastric projections are of similar shape in the sexes, but longer and nearer to each other in the male. In the male the teeth of the posterior margin are larger and occupy the whole of the margin, in the female they are separated by a wide interspace. Frontal sinus deeper cut in male than in female. In both sexes there are visible in dorsal view three small, acute teeth below the lateral border of the carapace, one on the subhepatic region and two just in front of the branchial wing.

Whitelegge (loc. cit.) mentions the varia- bility in the granulation. Besides the varieties which he observed we have some specimens, part of E.4821, in which, regardless of sex, all the granules of the carapace are flat and disc-like, but many of them are as if crowded up to a higher level, making a very uneven surface. As a rule the carapaces with this surface have higher and rougher protuberances, while the smooth, evenly paved carapaces have low, smoothly rounded protuberances which more often in the female than in the male, may be almost obsolete on the branchial regions. Milne Edwards (loc. cit.) may have described such a specimen, as he does not mention branchial tubercles. Regardless of the above characters, the posterior lobes are shallow in the female, protuberant in the male. PHLYXIA INTERMEDIA, Miers.

In the larger specimen the posterior margin is straight ; in the smaller one it is slightly convex; the two broad teeth thus formed are very obtuse angled. As Miers says, the largest of the lateral marginal tubercles is on the postero-lateral margin; of the smaller tubercles one is at the widest part of the carapace, forming a lateral angle, and another nearly half way to the hepatic protuberance. There is a suggestion of another tubercle in a slight marginal swelling a little behind the lateral angle. The only dorsal tubercle is that on the intestinal region in front of the posterior spine.

The specimens show a range in length from not quite two-thirds the extreme width in the old to nearly three-fourths the extreme width in the half grown. The marginal teeth in the old male resemble those fignred by de Haan 21 . In the small female, the lateral teeth of the wings of the carapace are shallow and obtuse angled ; the posterior margin of the last of these teeth is shorter than the corresponding margin of the adjoining tooth of the posterior border of the carapace.

This species was described by its author from a single small specimen only 9 mm. long. In the "Endeavour" collection there is a fine series of thirty-four specimens ranging from 18.6 to 82.4 mm. in length of carapace. Some modifications of the original description therefore need to be made to fit the adult. 142 " ENDEAVOUR " SCIENTIFIC RESULTS. The linea anomitrica is well marked in its posterior half, except near the posterior margin ; the anterior half is less distinct. The supraocular horns possess, besides an inner sub- terminal tubercle or spinule and two large outer spines, an outer spinule further from the tip than the inner one, and may have also a dorsal spinule further back and a fourth spinule on the outer margin of the anterior of the spines. The horns are relatively longer in the young than in the old. In the following table all the measures are of males and are taken to the bottom of the sinus between horn and rostrum : Reg. Carapace Rostrum Horn No. Sex. Length. Length. Length. E.5173 Male .... 20.2 5.6 12.6 E.3691 Male .... 23.6 6.4 15.6 K4776 Male .... 31.6 7.3 15.8 E.5135 Male .... 43 10 23 E.5131 Male .... 51.3 12 23 E.5128 Male .... 69.6 14 28 The surface of the carapace is covered with a short pubescence which is formed of single, acorn-shaped vesicles and embraces the granules and tubercles with which the carapace is roughened as well as the intervening spaces. The chelipeds are stout in the adult male, slender in the female and young male ; arms rough with tubercles and granules arranged mostly in longitudinal rows, and with a row of five spines above. Wrist furnished with larger tubercles and with granules. The palms of the female are slender and weak and remain so with age; they are almost cylindrical, very slightly flattened and of nearly uniform width, except at the articulations. The male, on the con- trary, shows a slender palm, only until the carapace (including rostrum) measures about 3 cm. in length, in one case 4 cm. (E.3685). It then changes by widening gradually to the distal end (E.4788), but soon grows more swollen, at first rather uniformly so throughout its length (E.4776), at the same time being a little compressed. It then becomes more and more swollen in the middle until in the largest specimen (8 cm.) the palm is remarkably inflated, its height in the middle 24.3 mm., its thickness in the middle 22.1 mm. BRACHY0RA. RATHBUN. 143 In both sexes the palms are covered with unequal granules, the largest of which are arranged in irregular rows. Fingers longer in male than in female, colour black, not reaching quite to either end. In the old male the fingers gape narrowly in the basal half; in the gape the dactyl has a truncate tooth, and nearer the palm the immovable finger has a low, rounded lobe. On the three following legs, besides the upper and lower rows of spines, there are other spines and sharp spinules or tubercles. The carpus and propodus are finely roughened with small, slender, horny spines, moving in sockets. The dactylus is armed with six rows of horny spines, two rows above reaching to the dark-coloured tip, a short row at the proximal end on the lower margin and on the inner and outer faces. The merus of the last pair of legs has three rows of spines and some scattered spinules, the only superior spine is at the distal end. The carpus and propodus are roughened as in the preceding legs, and the propodus has besides two rows of spines between which fits the row of spines on the dactylus. The abdomen of the male is about two-thirds as wide as that of the female. The first, second, third, fourth and sixth segments each bear a median spine or tubercle ; the third, fourth and sixth segments bear also a spine on each side. In the female the terminal segment is invaginated in the penultimate, a small lobe on each side of the latter being produced, but not attached, alongside the proximal end of the terminal segment.

In attempting to fit the species of Dromiidse into the genera of Borradaile's revision 22 of the family, emphasis has been placed on the presence or absence of an epipodite on the cheliped, and the approximation or separation of the ends of the sternal sulci of the female. Of the four genera represented in the collection, Dromidiopsis and Petalomera have an epipodite, Dromidia and Cryptodromia have none ; in Dromidiopsis and Dromidia the sternal sulci end together ; in Petalomera and Cryptodromia they end apart. Some of the other characters which have been given to these genera are not dependable, such as the knobbed or ridged legs and the thorn on the dactyl of the last leg. 22Borradaile Ann. Mag. Nat.

Twenty-five miles south-east of Double Island Point, Queensland, 33 fathoms; E.4473; one female. Length of carapace of male 011 middle line 78.2, greatest width 82.2 mm. Length of female 24.6, width 26 mm. The male specimen corresponds very well with de Man's description (loc. cit.) of a somewhat smaller male. The first antero-lateral tooth, however, is different on the two sides ; on the right side it is united with the so-called second tooth in a broad, truncate lobe ; 011 the left side it is conical, subacute, and the second tooth is obsolete. The young female resembles the male in most respects; it has, however, a subacute tooth, instead of a lobe, on the supraorbital margin; the epistome is more prominent and the tooth at either end is acute instead of tuberculiform. The sternal sulci are as described by Ihle, op. cit., pp. 28-29. The species does not quite agree with Borradaile 's defini- tion of the genus (op. cit., p. 298) ; the carapace is broader than long, the efferent branchial ridges though distinct are broken, the fifth leg though longer than the fourth is not nearly so long as the third, overlapping only slightly its propodal segment. 146 " ENDEAVOUR " SCIENTIFIC RESULTS.

RATHBUN. 147 In dorsal view the transverse fringe of longish hairs across the carapace just above the hepatic regions almost conceals the front. In front view we see in a subvertical plane a little more than a quarter section of a disc, the circumference of which is the fringe of hair above mentioned, and the straight sides, also fringed, run along the outer margins of the subhepatic region to a point between the ischiums of the outer maxillipeds ; this section, therefore, encloses the frontal and subhepatic regions, the orbits, the antenna? and the merus and a small part of the ischium of the maxillipeds. At the distal end of the propodus of the last pair of legs there is a small spine at the outer base of the dactylus ; on the outer surface of the propodus of the penultimate pair there are two small spines at the base of the dactylus. One of these spines on the penultimate leg may be sup- pressed, while sometimes there may be a second, small, supplementary spine on the last leg. The sternal sulci of the female are convergent, and terminate on a protuberance opposite the bases of the ambulatory legs of the first pair. DROMIDIA AUSTRALIS, sp. nov. (Plate xxxix.-xl., fig. 1.)

Three frontal teeth of similar shape, acute, median tooth much depressed and little visible in dorsal view. Three orbital, sub-spiniforrn teeth, one inner, suborbital, two supraorbital, the outer of which is separated by a fissure from a small suborbital lobe. Antero-lateral margin leading to the orbit and not to the buccal cavity, armed with four spiniform teeth, of which the first two are largest and subequal, and the last one smallest. A slightly projecting tooth behind the notch at the cervical suture. The basal segment of the antenna bears a flat, inward- pointing spine at its antero-internal angle. At either end of the epistome there is a small, sharp spine, while the neighbouring angle of the buccal cavity is spiniform. On the same margin where the outer angle of the maxilliped fits, there is a tubercle. When the maxillipeds are in place a subtriangular opening remains, leading to the efferent branchial channel. Merus of chelipeds unarmed; carpus with three distal prominences; a spine on proximal half of upper margin of right palm, two pointed tubercles on left palm, a tubercle at articulation with dactylus. Fingers gaping when closed. Carpus of first and second walking legs with a small tubercle at the distal end just below upper margin. These legs are shorter than the cheliped; last leg much longer than the preceding but shorter than the second ambulatory. On the propodus of the first prehensile leg there are two long spines opposing the dactylus (which flexes between them) and tw r o small spines on the posterior surface near the base of the dactylus. On the propodus of the last leg are likewise two small spines, but only one large spine forming a chela with the dactyl; furthermore, on the outer edge of the dactyl itself there is a spine, which is contrary to Borradaile's definition of the genus. This spine is present on the left leg but has been broken off the right leg. In the immature specimen they are well developed on both sides. The sternal sulci meet opposite the first pair of walking legs. In the immature female their extremities are further apart and do not reach beyond the line of the walking legs of the second pair. BRACHYOKA. RATHRUN. 149 Description of the male. The males have such a different aspect from the females that on first examination they were thought to be a different species. The males are larger but are not more convex with the increase in size; the additional width forms a flattened, and in the widest part, even a slightly upcurved rim, which adds to the appearance of moderate convexity. The median tooth of the front is more deflexed than in the fema.le, and in the smaller of the males is invisible in dorsal view. The spacing of the antero-lateral teeth is not just the same as in the type female, but neither does it correspond in the two males. The details of the antennal and buecal areas and of the chelipeds and legs are the same in the two sexes, excepting that the upper border of the palm has always two, in one case three, tubercles. In the larger male the propodus of the right last leg shows three spinules in place of the customary two. In the smaller male the right penultimate leg and the left last leg are abnormally reduced and the latter is devoid of a spine on the dactylus. The sixth segment of the abdomen has a shallow sinus in the lateral margins. Relationship. Allied to D. cranioides, de Man,- 3 which is more rotund, with furrows very ill denned, lateral teeth of front smaller, no tooth or spine at outer angle of orbit, antero-lateral margin bent down so that it is directed towards the suborbital tooth, and there is no spine on dactyl of last leg.

Between these angles there is an irregular row of small pits or depressions in the pubescence which are to be seen only when viewed from before. A deep median depression on the frontal region ; a short, deep furrow each side of the cardiac region, ending anteriorly in a pit, where it meets the well-marked cervical suture ; another furrow passes behind the cardiac region and forward to the cervical notch ; intestinal region depressed, from it a furrow runs laterally just in front of the posterior margin. Median tooth of front narrow, acute, and so denexed that only the tip is visible from above ; lateral teeth widely separated, their outer margins' continued by a rounded sinus to a tooth at the inner angle of the orbit ; this frontal border is conspicuously fringed with long setas. A fissure marks the outer angle of the orbit; while a triangular, pointed tooth occupies the greater part of the lower border. The anterior part of the antero-lateral margin is concave, the remainder is convex ; the two parts meet at a blunt, obtuse angle. There is a slight tooth behind the cervical suture, otherwise the lateral margin is entire. The edge of the epistome is nearly horizontal; the outer tooth is broadly triangular. Chelipeds rather small, shorter than the first two pairs of walking legs. The carpus and manus are ornamented with about four longitudinal rows of elongated sets which simulate ridges. The pubescence on the fingers forms a triangle on their outer faces, the margins bare and white. The propodal finger has four large prehensile teeth, two of which are terminal and fit tight against the tip of the dactylus. The dactylus is flat outside except its upper margin, which forms a raised rim. The first two ambulatory legs are rather narrow; their carpal and propodal segments are ornamented similarly to those of the cheliped. The fourth leg is slender, much longer than the third but not so long as the second. The propodus of the third, very short, leg has at its distal end, besides the spine which forms a chela with the dactylus, three small, slender spines or spinules on the outer surface. The propodus of the last leg has a spine at each of its distal angles, that at the lower angle very little shorter than the other, which forms a subchelate arrangement with the dactylus. BKACHYURA.

This species lias much in common with Drornidia spongiosa, Stimpson- 4 , which, according to the author's figure, has no antero-lateral angle, but a regularly rounded margin ; otherwise the features of the anterior and lateral margins appear to be similar. In spongiosa the legs of the last pair are broader, and both prehensile legs are devoid of the supplementary spines characteristic of insignis. CBYPTODROMIA OCTODENTATA (Haswell). (Plate xli.)

This species differs from Borradaile's description of Cryptodromia in that the walking legs are not knobbed or ridged and there is a thorn on the outer side of the dactylus of the last leg. The following description is taken almost entirely from manuscript prepared by Mr. A. R. McCulloch: "A series of eight specimens, 20-64 mm. wide, shows the same variation as noted by Baker in the armature of the antero-lateral borders of the carapace and the upper margin of the hand. 24 Stimpson Smithson. Misc. Coll., xlix., 1907, p. 171, pi. xx., fig. 1. 152 "ENDEAVOUR" SCIENTIFIC RESULTS. ' ' The carapace is broader than long, and strongly convex. It is covered with coarse, erect hairs, which have a brush of minute lateral sets 1 near their tip. The cervical groove is usually distinct, sometimes rather indefinite. A median longitudinal groove between the orbits, and a broad, shallow one on each side of the cardiac region. Front cut into three teeth, of which the middle one is on a much lower plane than the others ; in the smallest specimens it is directed downward, and in the other projects somewhat forward. The outer teeth form the inner orbital angle. "The orbits have a conical tooth in the centre of their upper border, which is sharper on the young. The outer angle is prominent, sometimes forming a tooth, and below it there is a V-shaped notch which may be broad, or very narrow. Inner angle of the suborbital lobe dentiform. The antero-lateral borders are armed with four or five teeth which are variable, the small specimens having four and the larger ones four or five; in some examples the fourth tooth is replaced by a blunt lobule, while others have a small denticle at the base of the fifth tooth. Postero- lateral borders slightly convergent, and they have either a blunt tooth, or a lobule immediately behind the cervical groove. "The subhepatic region is swollen into an obtuse pyra- midal projection. The antero-external angle of the buccal cavern is spiniform, and there is a conical tubercle a little farther back. A broad spiniform tubercle projects obliquely inward and backward on the basal antennal joint, and both the inner and outer angles of the second joint are produced. The ischium of the external inaxillipeds is longer than broad, and is divided anteriorly ; its surface is slightly hollowed. The merns is pentagonal, and is much longer than broad, the outer surface is usually somewhat sinuous. The palp is attached below the anterior internal angle. The exopod is about three and one-half times as long as broad, and its greatest width near the base is about half that of the merus. " The inner and outer edges of the ischium and rnerus of the chelipeds bear rows of rounded tubercles. The inner angle of the wrist is armed with a large obtuse spine, and the antero-internal edge bears, in the larger specimens, rounded tubercles. The crests of the hands bear from one to seven similar tubercles. The last two pairs of legs BRACHTDRA. RATHBDN. 153 chelate. The penultimate legs always have two large spines facing the dactyli, and sometimes several other smaller spines. The last pair usually have only one large spine, that facing the dactylus ; on the outer side of the dactylus a little way from the base there is a small spine, the tip of which may be broken off. The abdomen of both sexes consists of seven free seg- ments, and has a broad raised ridge along the middle line. The last segment in the male is triangular, and the pen- ultimate one is deeply excavated on either side. Those of the female decrease regularly in breadth from the third to the seventh. The sternal sulci of the female end wide apart just behind and close to the articulation of the chelipeds. The eggs are very large and numerous, being 2 mm. in breadth. PETALOMERA LATERALIS (Gray].

McCulloch :- "All parts except the tips of the fingers and dactyli are thickly covered with tomentum. ' ' The carapace is much broader than long, and is convex. The tomentum forms pits and strong ridges, which define the regions very clearly, but when it is cleaned away they become less conspicuous. There is a row of small circular pits starting from between the second and third teeth of the anterolateral borders and stretching obliquely forwards, meeting between the orbits. These pits cannot be seen at all when the tomentum is taken off, but there is a distinct but flat ridge which they follow. The front is cut into three teeth, the centre one being very small, acute, and on a much lower plane than the two outer ones, which are large, obtuse and form the inner supra-orbital angle. There is a deep, or well-marked, median groove between these teeth. 156 "ENDEAVOUR" SCIENTIFIC RESULTS. "The orbits are large. There is a large tooth in the middle of the upper orbital border, which is joined by a very slight curve to the large obtuse tooth at the inner supraorbital angle; these two together form a considerable projection over the orbit. The suborbital border is denti- form, and is easily seen in a dorsal view, it being situated outside the large projection of the upper border. The outer angle seems to form a continuous line, but if the tomentum be scraped away it shows that the borders are separated by a groove. The antero-lateral borders are cut into four teeth, the first being the smallest and on a much lower plane than the other three, it being on a slightly lower level than the outer orbital angle. The second and third are large, the distance between them being distinctly less than that between the first and second or third and fourth. The latter is small, and is situated behind the cervical groove. There is a small tubercle, which may either be acute or very flat, on the ridge behind the cervical groove, and almost at the base of the fourth tooth. Postero-lateral borders are slightly convergent and are convex. "There is a small acute tubercle on the subhepatic region situated midway between the first tooth of the antero-lateral border and the endostome, and another smaller one at the base of the suborbital lobe. "The crest of the merus of the cheliped bears a few small granules under the tomentum. The carpus is nodular, and at the inner angle there is a sharp tubercle covered by a tuft of long silky hairs. The tomentum on the outer surface of the hand forms longitudinal ridges. Both the inner and outer surfaces of the movable and immovable fingers are strongly grooved, and along these grooves the tomentum grows. The inner surface of the hand and fingers, and the lower edge of the merus, bear the long silky hairs already mentioned. There is a space between the fingers at their base. In some specimens they meet only at the tips, while in others they meet the last half of their length. There are seven or eight teeth along their outer borders, which interlock perfectly when the fingers are closed. ' ' The first and second ambulatory legs bear strong spinu- lar nodules on their carpi and propodi. Both the third and fourth pairs are flattened, and have no nodules ; the fourth pair being dorsally situated." The sternal sulci of the female end far apart in a line between the coxae of the first and second ambulatory legs. EXPLANATION OF PLATE XIX. Carcinoplax victoriensis, sp. nov. Male holotype.

Nine small specimens from Queensland, 350-465 mm. long, exhibit but little variation, though the dorsal and cephalic tubercles are a little more numerous and better developed in some than in others. They do not differ from specimens of the same size from Port Jackson. 158 "ENDEAVOUR" SCIENTIFIC RESULTS. Synonymy. Garman unites 7?. philippi Muller aud Henle, with R. banksii M. and H., but certain details of the structure of the snout and the position of the nostrils, as described under R. pMlippi, differ from those of R. banksii. It is, therefore, doubtful that the two names refer to the same species. According to Haacke, the typical specimens of his R. rincentianus were deposited in the South Australian Figures 1-4.

MCCULLOCH. 159 examination by Mr. E. R. Waite; these are figured in the accompanying illustration. Though still very small, the embryos indicate that R. vincentianus is identical with R. banksii; the dorsal tubercles can only just be traced but they agree in their disposition with those of R. banksii, while the nostrils are disposed as in that species. Localities. Ogilby (Joe. cit.) observed this species in the trawl eleven times while the ''Endeavour" was in Queensland waters. Specimens are preserved from the following localities.

Three specimens 265-273 mm. wide, differ considerably in general appearance from a larger 470 mm. example which I have figured (loc. cit.), and agree much better with Waite's figure quoted above. The anterior portions of the ventrals are covered by the pectorals in the smaller specimens, while they are fully exposed in the larger one, which makes the latter appear proportionately longer. The spiracles are less open in the "Endeavour" specimens, and therefore appear smaller. The exact shapes of the dorsal and caudal fins are variable, as noted by AVaite, but they are generally broader and rounder than in the larger 160 "ENDEAVOUR" SCIENTIFIC RESULTS. specimen. The pectoral disc is wider in one of the "Endeavour" specimens than in the others, its length being 1-25 in the breadth as against 1-16-1-18; the dorsal surface of the disc is more uniform, there being less of the underlying skeletal structures visible than in the larger example. A careful comparison of all four specimens, however, leads me to the conclusion that they are merely variations of the one species. Localities.

Supra- ventral almost midway between the ventral lin and the lateral line. Four pairs of ventral photophores, the second high above the others. Three superanals on each side, the upper behind an oblique line cutting the two lower ; it is more widely separated than the other two, but is separated by a short space from the lateral line. First anteroanal elevated, but not so high as the middle superanal ; three more form an oblique row on the right side and four on the left. Lower posterolateral obliquely above and behind the last anteroanal, the upper not touching the lateral line. Five posteroanals in an oblique row on the left side and six on the right. Four precaudals, the last separated from the others, but not reaching the level of the lateral line. Described and figured from a specimen 188 mm. long, from the Great Australian Bight, 350-450 fathoms. It is denuded of scales, but their position is clearly shown by the scale-pits and markings, and its luminous organs are well preserved. Variation. Fifty-two other specimens, all in a bad state of preservation, appear to have their photophores similarly arranged, but one example has only four autero- anals and six posteroanals, as is shown on the right side of the specimen described. These are illustrated in PI. xliii, fig. 2. Localities. Fifty-four specimens, 118-172 mm. long, are preserved from the following localities : Great Australian Bight, south from Eucla, 350-450 fathoms; 14th May, 1913.

The genera Xenodermichthys Giinther, Aleposomus Gill, and Rouleina Jordan are closely allied, but appear to be distinguished as follows: A.

Gill-openings extending well above the pectorals; mouth large. ALEPOSOMUS. C. Dorsal and anal fins long, with more than 25 rays. Subgenus ALEPOSOMUS. Includes copei Gill (syn. socialis Vaillant) and cyaneus Zeugmayer. CC. Dorsal and anal fins shorter, with 20 or less rays. Subgenus ROULEINA. ALEPOSOMUS Gill. Subgenus ROULEINA Jordan. Aleposomus Ronle, Bull. Mus. Hist. Nat., 1915. 2, p. 46 (guntheri} scnsu lato. Rouleina Jordan, Classification Fish., 1923, p. 122 (guntheri). Rouleina is only subgenerically distinct from Aleposomus, differing only in having shorter dorsal and anal fins. By the kindness of the Director of the Museum d'Histoire Naturelle, I am able to compare my specimens of R. squamilaterus with an example of A. socialis Vaillant (= copei Gill). I find them similar in all larger structural details, though the lateral line is without modified scales in A. socialis. They differ from Xenodermichthys in having the gill-openings extending far above the bases of the pectoral fins and in their larger mouths. A bony stay across the operculum is well developed, which is apparently wanting in Xenodermichthys. Key to the Species. A. Lateral line indistinct, without scales. B. D.15, A. 14. guntheri Alcock.

Head, from premaxillary syinphysis to end of opercnlar lobe, 3-8 in the length to the base of the caudal rays ; depth at the pectorals 5-9 in the same. Transparent disc of the eye considerably smaller than the orbit, 4-0 in the head; bony orbit 3-3 in the same. Snout 1-6 in the orbit. Body elongate, compressed. Profile forming a convex curve upwards from the snout to the back; the snout a little prominent. Interorbital space flat; its bony portion is about half as wide as the eye but the bones are so soft that they cannot be satisfactorily measured. Nostrils large, close together; the anterior circular, the posterior a pear-shaped opening. Eye entirely within the anterior half of the head and close to its upper profile. Preorbital very narrow and mem- branaceous. Mouth large, oblique; the maxillary is broad and rounded posteriorly, with a well developed supramaxillary, and reaches backward almost to the vertical of the posterior margin of the eye. Mandible closing within the premaxillaries but with a very prominent syinphysial angle. Preopercular angle partly free, the rest of its margin covered by dermal membrane. Opercles membranaceous, supported by stronger bony ridges curving obliquely downward to an inframarginal angle; a broad skinny border forms the margin of the gill-opening. Gill-openings very wide, commencing high above the pectoral and only a short distance below the lateral line; they extend forward to below the eye and the membranes are quite free from the isthmus. Four gill-arches, with a slit behind the fourth ; pseudobranchise present. About nineteen broad gill-rakers on the lower limb of the first arch, of which those at the posterior angle are about half as long as the orbit. Premaxillaries with a single row of minute cardiform teeth which extends backward onto the lower edge of the maxillary; a similar row on each side of the mandible; palate toothless. Tongue large and free. 164 "ENDEAVOUR" SCIENTIFIC RESULTS. Body naked, the soft skin closely wrinkled into minute, longitudinal folds; the angular muscle-segments well defined. Lateral line a salient canal supported by close-set, scale-like rings with points almost meeting in the middle line; a minute tubercle is present at the base of each ring. It commences above the preoperculum and runs obliquely downward to the middle of the body and terminates on the middle caudal rays. Branches of the lateral line system extend forward onto the head ; one crosses the nape and another extends forward on each side of the upper surface of the head to the snout; still another canal forms an obtuse angle near the postero- inferior portion of the eye and extends along the pre- orbital. Each of these is marked with open pores. Photophores are distributed as in the accompanying figure and are more or less similarly disposed in several specimens. A row is present beneath the eye and several are scattered behind it. One is on the maxillary and two on the cheek behind its posterior margin. A row extends along each raruus of the mandible and others are present upon the throat and gill-membranes. The operculum, suboperculum, and preopercular border each bear scattered photophores as shown in the figure. Minute papillae are present on parts of the head which apparently bear microscopic luminous organs. The body bears numerous photophores which are most plentiful on the lower surfaces; in the abdominal region they are disposed in transverse rows. Similar photophores are present on the dorsal and anal fins, the base of the caudal, and the lower surfaces of the ventrals. The anal fin is entirely within the posterior third of the body but the anterior dorsal rays are situated in advance of it. Both fins appear to be somewhat rounded with their median rays longest and approximately two- thirds as long as the base of the fin. Ventral nearer the base of the caudal fin than to the anterior margin of the eye, its adprcssed rays not quite reaching the vent. Pectorals inserted low on the sides; the second ray appears to be longest and reaches much less than half its distance from the ventrals. Caudal deeply forked. Colour. Deep violet-black; the head lighter. A naked bluish stripe at the bases of the dorsal and anal fins. FISHES. MCCULLOCH. 165 Described and figured from an example 182 mm. long without the caudal fin. It is the smallest of fourteen specimens, but is in a better state of preservation than I;irgvr examples. Variation. Fourteen specimens, 182-266 mm. long without the caudal fin, exhibit similar variation in their proportions and number of fin-rays to that noted by Koule (Bull. Mus. Hist. Nat. 1915, 2, p. 42) in Aleposomus socialix. A tabulation of the measurements of the fourteen specimens shows that they vary individually and irrespective of size. D. 19-21, A. 16-19, P.7-9, V.7-8. Head 3-74-1 in the length to the base of the tail; depth 5-7-6-4 in the same. Eye 3-8-4-2 in the head; orbit 3-0-3-3 in the same. Snout 1-6-1-8 in the orbital diameter. * Idcnti /.(/. These specimens do not quite agree with the proportions of R. squantilaterxs, but having tabulated their range of variation, and allowing for the fact that Alcock's description and figure were prepared from a single young example, I consider the differences too slight to be of specific value.

Mouth wide, the upper jaw largely formed by the maxilla, which extends backward almost to the preopercnlar angle; mandible projecting beyond the upper jaw when the mouth is closed. Teeth well developed, but without enlarged fangs; two rows on the premaxillaries and mandible, and one on the maxillary; teeth on the vomer and palatines with teeth. Gill- openings very wide; gill-rakers slender; no pseudo- branchiae. Photophores very conspicuous, in two rows on each side of the abdomen and in one from the vent to the caudal fin. Dorsal fin short, above the interspace between the ventral and anal fins; its posterior rays above the origin of the anal; adipose dorsal present. Anal fin long, with 24-29 rays. Caudal forked. Pectorals and ventral s well developed. Type. P. illustris sp. nov. This genus is closely allied to PliotlcJithys Gtinther, but differs in its dentition and in having the dorsal fin placed somewhat farther back. Photichthys has several canines in the premaxillaries, and about seven longer fangs on each side of the mandible ; a small canine on each side of the vomer, and each palatine bears a long FISHES.

Third dorsal ray (20) 1-5, fourth anal ray (17) 1-8, pectoral (22) 1-4 in the head. Head and body compressed ; the dorsal and ventral profiles almost evenly arched. The profile rises in a gradual curve to the nape from the conical snout; inter- orbital space almost flat, with bony crests above each eye Avhich converge on the snout. Nostrils close together, near upper surface of snout; posterior larger than the anterior. Eye close to the upper profile and situated within the anterior half of the head. Mouth oblique; upper jaw formed by the prernaxillary anteriorly, but by the maxillary posteriorly, which reaches backward to the base of the preoperculum ; it is a little expanded posteriorly, and is traversed by a raised ridge along its length. The cheek is covered by some large and very thin scales, and one extends over a large portion of the maxillary. The premaxillary and maxillary with curved teeth ; these appear to be arranged in two rows on the premaxillaries ; the outer being the larger. Maxillary teeth in a single row, larger than those on the pre- maxillary and with smaller ones set between them. Mandible projecting beyond the upper jaw, with two 168 "ENDEAVOUR" SCIENTIFIC RESULTS. rows of similar teeth. A few scattered teeth on the vomer, and a short row on each palatine; no enlarged fangs. Preoperculuni very narrow; its anterior edge forming a pronounced ridge. Operculum, suboperculum and interoperculum each separate ; their surfaces marked with concentric striae. Four gill-arches ; a slit behind the fourth. No pseudo- branchiae. Gill-rakers slender, the length of those at the angle of the first arch about equal to the interorbital width ; twelve on the lower limb of the first arch. Body now naked but showing traces of large scale-pits. Photophores. A large photophore is present on the preorbital, another above the suspension of the pre operculurn, one beneath the suboperculum and one beneath the interoperculum. Nine form a row between the bases of the brauchiostegal rays. Nine pairs are arranged along the isthmus and one on the base of the pectoral. Eleven more form a row to the ventral and eight between the ventral and the anal. There are seventeen in a row from above the pectoral base to above the vent. Seventeen above the anal, of which the anterior is placed higher than the others, and five more to the base of the tail. The origin of the dorsal fin is nearer the base of the caudal fin than the snout and is situated well behind the ventral, its posterior rays overlapping the anterior ones of the anal. Adipose dorsal fin well in advance of the termination of the anal. The anterior anal rays are much longer than those following them. Pectoral reaching about three-fourths its distance from the ventral; caudal forked. Colour. Brown above, silvery on the sides; the junction of the two colours sharply defined. Opercles blackish; each caudal lobe with some black rays posteriorly. Described and figured from a specimen 158 mm. long, which, however, is considerably damaged, and details have been studied in other specimens. Variation. Nine specimens, 103-148 mm. long with out the caudal fin, exhibit some little variation. D. 11-12; A.27-32 ; P.10-11 ; V.7. The head is 4-24-6 in the length and the depth 5-0-5-9 in the same.

This species differs from P. corythceolus Alcock, in its larger number of dorsal rays and photo- phores. It is very near P. africanus Gilchrist and von Bonde, but the number and arrangement of the photo- phores in that species are different from those of P. ill list r is, in which they are uniform in all of my nine specimens. P. africanus has only 25 rays in the anal fin as against 27-32 in P. illustris. Localities. Great Australian Bight, south from Eucla, 350-450 fathoms ; 14th May, 1913.

(Plate xlv, fig. 2.) Br. 10; D.13; A.25 ; P.16; V.7; C.19. About 44 muscle bands between the shoulder and the base of the caudal fin. Depth (30-5 mm.) 3-3 in the length to the hypural joint (103) ; head (31-5) 3-2 in the same. Eye (12) 2-6 in the head; interorbital width (6-5) a trifle less than the length of the snout (7), which is 1-7 in the eye. Fourth dorsal ray (18) 1-7, third anal ray (13) 2-4, and pectoral fin (25) 1-2 in the head. Head and body strongly compressed ; the dorsal and ventral profiles almost evenly arched anteriorly. Inter- orbital space a little concave, with arched crests above the eyes, from which ridges extend forward converging on the snout. Nostrils close together in the middle of the snout. Eye touching the upper profile. Mouth oblique; the anterior fourth of the upper jaw formed by the premaxillaries, the remainder by the large maxillary which reaches backward to the vertical of the posterior margin of the eye; it is but little expanded posteriorly, and its hinder portion is overlain by a large spatuliform supramaxillary. Premaxillaries, maxillaries, and man- dible each with a single row of curved needle-like teeth, of which those on the maxillaries are no larger than else- where. One or two small teeth on each side of the vomer. 170 "ENDEAVOUR" SCIENTIFIC RESULTS. and a few very small ones on each palatine. Mandible projecting beyond upper jaw. Preopercular angle rounded ; its anterior margin forms a raised crest behind the eye. Operculum, suboperculum and interoperculum almost membranaceous with smooth surfaces. Four gill-arches, a slit behind the fourth. No pseudo- branchiae. Gill-rakers slender, the length of those at the angle of the first arch equal to that of the snout ; sixteen on the lower limb of the first gill arch. Body denuded of scales. Photophores. A large photophore is present on the preorbital, another behind the eye above the suspension of the preoperculum, and one at the preopercular angle behind the maxillary ; two are on the suboperculum, one above the other and separated by a black, metallic-hued space, and six form a row on the gill-membranes between the branchiostegal rays. Six are arranged in a row on each side of the isthmus, the hinder ones curving upward to the base of the pectoral. Ten pairs of rounded photophores are present on the ventral surface between the thorax and the ventral fins, and seven dumb-bell shaped ones on each side beneath the pectoral fins. Twenty-one form a series commencing above the ventral fin, which first dips sharply downward and then runs obliquely upward to above the origin of the anal, where it rises abruptly and extends backward subhorizontally to end above the eleventh anal ray; the anterior photo- phores of this series are much larger than the others. Five larger photophores are united in a row above the middle of the anal, and a row of thirteen more is present on each side of the lower surface of the caudal peduncle. Origin of the dorsal fin a little nearer the snout than the base of the tail, and a little behind the vertical of the ventrals; its posterior rays are above the anterior anal rays. Adipose dorsal well developed, situated above the posterior portion of the anal, its length equal to about two-thirds the width of the eye. Anterior anal rays much longer than those following them. Pectoral reaching backward to beyond the ventrals. Ventrals imperfect, broken. Caudal deeply forked. Colour. Occiput, portion of opercles, throat and chest black, with iridescent colours.

D. 12-14; A.24-25; P.16-17; V.7. The number of photophores on the sides of the abdomen and before the ventral fins is constant, but those in the curved series behind the ventral vary from 20-21 ; there are always live together above the middle of the anal, and 12-11 pairs beneath the caudal peduncle. Depth 3-1-3-4 in the length to the hypural joint; head 3-2-3-8 in the same. Eye 2-5-2-7 in the> head. Affinities. This species is so similar to A. ephip- piatus Gilbert and Cramer, that I separate it with much hesitation. The number of dorsal and anal rays is con- sistently greater in A. iridescens, and the numbers of photophores in the branchiostegal, ventro-anal, and caudal series is slightly different from those of A. ephippiatus.

Preoral portion of the snout (14) 2-4 in its length; interorbital width (6) 2-1 in the eye. Pectoral fin (55) 1-3, caudal fin (45) 1-6 in the head. Second dorsal ray (33) 2-2, fourth anal ray (22) 3-3, and ventral fin (29) 2-5 in the head. Body elongate, tapering to a very slender tail; the profile is convex on the nape. Snout conical, rounded in a horizontal plane; it is formed of flabby integument supported by cartilages which can be felt through the skin. Interorbital space flat. Nostrils close together, situated a little in front of the eye, the anterior with a small dermal lobe. Eye large, covered by membrane. A large channel extends backward from each side of the snout, across the cheek to the preoperculum, and a small one on each side of the mandible to the operculum. Opercular bones membrauaceous, projecting backward beyond the gill-covers. Mucigerous canals cross the nape and postocular regions. Maxillary not quite reaching the vertical of the anterior border of the eye, and terminating in a small spine; lower jaw closing within the upper. Bands of villiform teeth on the jaws, palate, and tongue. Gill-openings extending forward to beknv the front margin of the eye, their membranes free from the isthmus. Seventeen gill-rakers on the lower limb of the first arch, which are slender posteriorly, and become shorter anteriorly; those at the angle are about one-third as long as the eye. Four gills, an opening behind the last. Thin cycloid scales cover the upper surface of the head and extend far forward on the snout; they were also present on the cheeks and opercles. Very few scales remain upon the body, though the scale-pits are distinct; such as are present are thin and concentrically striated. The scales of the lateral line were probably not enlarged. Some cycloid scales remain on the dorsal fin and anterior portion of the anal. Origin of the dorsal fin nearer the vent than the hinder margin of the eye; its first ray is simple, the others are branched, and the margin is rounded. Pectoral fin inserted high up on the side, with a narrow base ; the fourth ray is longest, and reaches beyond the vertical of the origin of the veutrals, but not so far as that of the dorsal fin ; the median rays are branched, and the lower ones are very small. Yentrals inserted well in FISHES. - MCCULLOCH. 173 advance of the dorsal but reaching the vertical of the ninth dorsal ray when adpressed; they are united by membrane only at their bases; a short spine-like ray precedes the first articulated one, which is simple while the others are branched. The anterior anal rays are branched and higher than the body above them, but those following them are simple and decrease in length until towards the posterior third of the tail where they become gradually longer. A short interspace separates the last anal ray from the caudal, but the two are apparently united by membrane. Upper caudal ray long and branched, the others decreasing in length downwards. Colour. Whitish after long preservation, the scale- pits margined with brown on the upper parts. Eye and gill-covers black. Posterior third of the anal fin and the caudal fin with brown margins. Described and figured from the holotype, 545 mm. long. Variation. Two para types, 535 and 595 mm. long, have twelve rays in the dorsal fin, and only five or six rays in the caudal. Affinities. This species belongs to the typical section of the genus Halosaurus, characterised by the presence of scales on the upper surface of the head, and by having the scales on the lateral line not or but little enlarged. Its very long pectoral fins distinguish it from most of its allies, but it is very similar to H. oweni from Madeira and the Atlantic, differing principally in having a longer head as compared with the trunk.

MCCULLOCH. 175 The backward process of the premaxillaries forms a tubercle on the snout from which a median ridge pro- jects backward to the interorbital space; the latter is almost flat. A broad septate canal, covered with mem- brane, extends backward from above the eyes to the shoulder; another extends around the preopercular border, and one along the suborbital region. The whole head appears to have been scaly, though only a few cycloid scales now remain on its under surface. Oper- cular margins thin and rounded. Maxilla extending backward to behind the vertical of the posterior orbital margin and forming an obtuse angle posteriorly. The teeth form a narrow band in each jaw, separated by an interspace at the symphysis. The scales of the body appear to have been of moderate size but none now remain. There seem to have been about six" between the lateral line and the inter- space between the two dorsals, but the position of the lateral line itself is indefinite. The vent is situated immediately in advance of the anal fin. The first dorsal originates a little behind the vertical of the base of the pectoral; it is preceded by a minute spine, but the following spine is elongate, with a fila- mentous tip ; the succeeding rays decrease in length back- ward. The second dorsal commences immediately behind the termination of the first; its anterior ray is highest but the others decrease only slightly in length backward, and its posterior portion is rounded. The anal com- mences beneath about the tenth ray of the second dorsal, and is preceded by two short spines. The first four rays of the anterior portion are long, but the others decrease in length backward. Immediately following and connected with the first portion of the anal is a long series of short slender rays which increase in length backwards as they approach the posterior elevated portion of that fin, which is rounded. The ventrals are inserted in advance of the preoperculum and are com- posed of separate filiform rays; the two anterior are united at their basal portion and the first, which is divided, reaches backward to the base of the first anal ray. Pectoral pointed ; the sixth upper ray longest, but not nearly reaching the vertical of the vent. The caudal extends around the end of the tail with many short rays above and below. The lower rays are longer than the upper and form an angular lobe. 176 "ENDEAVOUR" SCIENTIFIC RESULTS. Colour.

Another scaly ridge extends forward from the ocular margin, above and around the nasal region. The occiput and interorbital regions are without prominent ridges. The lateral ridge from the rostral tubercle to the preopercular angle is armed with thickened spinate scales. Nostrils close together, a little before the eye; the anterior is circular, and the posterior forms a curved slit. Maxillary reach- ing backward to below the hinder third of the eye. A broad band of villiform teeth in each jaw. Mental barbel almost half as long as the eye. Preopercular angle form- ing an obtuse point ; suboperculum produced into a sharp angle. Body scales with many subparallel rows of spinules on their exposed surfaces; these are of equal size and number as many as sixteen on some scales below the first dorsal fin. The median scales before the dorsal fin do not form a crest as is often present in C. fasciatus. The vent is situated a short distance before the anal fin; a median naked sulcus is present between it and the ventral fins. Lateral line forming a low curve anteriorly. Anterior dorsal spine minute, the second is smooth and its filamentous tip projects beyond the first ray; when adpressed it reaches the origin of the second dorsal. The interspace between the two dorsals is twice as long as the base of the first. The rays of the second dorsal are very low anteriorly, but increase in length backward. First ventral ray filamentous, reaching the origin of the anal. The tail is incomplete in the type, but in another specimen, 275 mm. long, the head (56 mm.) is 4-9 in the total length. Colour. Head and body uniform grey. A small black spot on the lower pectoral rays forms a contrast with the light coloured base of that tin which is sharply defined in a dark bluish area. The filamentous ventral ray is whitish, the others bluish-black. Described and figured from a specimen, 230 mm. long, from 150 fathoms, east of Sydney. Affinities. This species is very similar to C. fasciatus but differs consistently in having a somewhat smaller eye, which is subequal to instead of longer than the post- orbital portion of the head, and in having scales on the 180 "ENDEAVOUR" SCIENTIFIC RESULTS. lower surface of the head, behind the angle of the mouth. The scales in advance of the dorsal fin are less rugose than those of fasciatus and the body appears to be without dark cross-bands. Thirty specimens, 133 to 275 mm. long, are preserved. The eye of the smallest is but little longer than the post- orbital portion of the head, and scales are present on the area behind the mouth as in the adults. All of the "Endeavour" specimens are largely denuded of scales, so an example in the Australian Museum collection (1.15247) has been selected as the holotype. Localities.

Six examples, 235-240 mm. long, have been compared with the holotype which is only 138 mm. long. The edges of the snout are a little less curved in the "Endeavour" specimens than in the small holotype, but they agree in all other details. The following are the proportions of the largest : Head and trunk (79 mm.) 2-03 in the tail (161); head (55) 4-3 in the total length. Depth before the ventral fins (24) 2-2, eye (16-5) 3-3, and snout (22) 2-5 in the head. Interorbital width (9) 1-8 in the eye. Second dorsal spine (24) 2-2 in the head, and 1-3 in the postrostral length of the head (32). Pectoral fin (20) 2-75 in the head. The eye is 1-3 in the snout, and longer than the postorbital portion of the head. The width of the mouth at its posterior angle is 2-5 in the breadth of the head at the same point, and the maxillary reaches backward beyond the vertical of the middle of the eye. The spinules on the scales of the sides are directed obliquely backward, and form ten to twelve subparallel ca rinse of about equal strength. The body is without FISHES.

Depth (36-63) 1-1-1-2 in the head. Orbit (14-26) 2-8-3-0 in the head, and 1-1-1-2 in its postorbital portion (17-30). Bony interorbital width (12-24) 1-0-1-1 in the orbit. Identity. The characters relied upon to distinguish the four known species of Malacoceplialus are largely proportional measurements of a few individuals of each. They are far from satisfactory, and I find nothing to distinguish the Australian specimens from M. Ice-vis as described and figured by Holt and Calderwood (loc. cit.}. Range. Though originally described from Madeira, M. hrvis has since been taken in the North Sea, north and south Atlantic Ocean, and the Indian Ocean. It is therefore not surprising to find it in southern Australian waters, because several other deep-sea fishes with a similar range have been obtained by the "Endeavour" in the Great Australian Bight.

Mus. li, 1916, p. 163) the dental characters and the armature of the dorsal spine are variable within Coryphcenoides, and they suggest the identity of Optonurus with that genus. I have no species of Coryphwnoides with characters approaching those of Optonurus for comparison, and therefore retain the genus only because its validity has not been definitely disproved. FISHES. MCCULLOCH. 183 Nomenclature. Richardson used Lepidorhynchus as an alternative generic name for denticulatus in case that species proved to be distinct from Macrourus, and it was duly recorded by Agassiz and Scudder. No generic definition accompanied the name, but its association with a genotype gives it priority over Optonurus which was proposed for the same species later. Jordan (Gen. Fish, iii, 1919, p. 398) attributes the name Lepidorhynchus to Bleeker, 1879, and quotes L. villosus, a species of Trachonurus, as the orthotype; but a reference to Bleeker's paper leaves no doubt that he merely utilised Richardson's name.

Eye (26) almost 3 in the head; the length of the snout is equal to the mterorbital width (17) and 1-5 in the eye. Pectoral fin (62) 1-2 in the head. Snout and interorbital area covered with a delicate membrane enclosing deep cavities between thin bony crests; a median crest arises before the vertical of the front margins of the eyes and slopes obliquely downward and forward to form a small angle anteriorly; a second crest is present on each side, curving over the nostrils 184 "ENDEAVOUR'' SCIENTIFIC RESULTS. and likewise forming a small anterior angle. A paired crest commences at the middle of the orbital margin and, converging towards its fellow, disappears on the nape. Broad septate canals, covered by delicate membrane, extend backward from the snout to below the hinder margin of the eye, and then turning sharply upward unite with a similar canal, which runs backward from the interorbital region to the shoulder; another broad canal is present between the inner crest and edge of the pre- operculum. Opercular bones thin, their margins mem- branaceous; suboperculum produced backward as an angular lobe. Nostrils close together, a little before the antero-superior angle of the eye; the anterior round, the posterior an oblique slit. Eye very large, the orbital margin just cutting the profile. Mouth oblique, the maxillary reaching backward to below the posterior third of the eye; it is very narrow posteriorly. Premaxillaries with an outer row of strong curved cardiform teeth, which are spaced and largest anteriorly ; behind these is a band of villiform teeth formed of narrow oblique rows with grooves between them. Mandible with a single row of teeth which are small anteriorly but become larger on the sides. Palate and tongue toothless. A small mental barbel. Anterior gill-rakers of first arch tubercular and unarmed, ten on the lower limb of the first arch ; those on the hinder edge are larger, pedunculate and armed with spines. Head and body almost entirely denuded of scales, only a few remaining on the posterior half of the inter- orbital region, on the lower surface of the mandible, and on the under surface of the thorax and abdomen. A scale from near the vent is armed with long spines upon its exposed surface, arranged in oblique rows, and directed obliquely outward and backward. No naked groove before the vent. The dorsal fin originates behind the vertical of the pectoral and ventral fins, and the length of its base is but little more than that of the eye; the first ray is without articulations and its edges are smooth. The second dorsal commences far behind the tip of the adpressed first dorsal (in other specimens the interval between the two fins is variable, the anterior rays of the second being overlapped by the tip of the first dorsal in young examples) ; the anterior rays are minute but FISHES. MCCULLOCH. 185 they become longer backwards and are as long as those of the anal near the tail. Anal rays simple, highest anteriorly. Pectoral rays very slender, the median ones divided. First ventral ray with a short filament, reaching beyond the origin of the anal. Upper portion light in colour after long preserva- tion. The throat, whole abdominal area and the ventral surface of the anterior half of the tail are bluish black. Fins without markings. Described and figured from a specimen 460 mm. long, from 350-450 fathoms in the Great Australian Bight. Forty-six specimens, 125-533 mm. long, are preserved, but very few retain any of their scales. The young examples are very similar to the adults, though their teeth are relatively smaller. Localities. This species is not uncommon in deep water eastward of Bass Strait. It was first described from South Australia, and has since been taken in New Zealand waters and at the Kerinadec Islands.

Synonymy. The identity of Nesiotes and Pseudo- chromis has been recorded by Jordan, whom I supplied 186 "ENDEAVOUR" SCIENTIFIC RESULTS. with information after examining what were believed to be the types of N. purpurascens in the Queensland Museum. These specimens are duly registered and labelled, but they differ from De Vis' generic and specific descriptions in so many details that it is difficult to believe that they are the types. De Vis counted twelve instead of three dorsal spines, and he found the lateral teeth "confluent, with distinct serra- tion," whereas they are merely juxtaposed in the "types" ; he recorded the depth of the body as 3-5 in the total length instead of 4-1. In view of these discrepancies, nothing but the notorious inaccuracies of De Vis' writings justifies one in accepting these specimens as the types of Nesiotes purpurascens.

L. lat. 28/8 ; about 40 rows of scales between the operculum and the hypural joint. Total length 68 mm. Depth (17 mm.) 3-1 in the length of the hypural joint (54) ; head (18) 3-0 in the same. Eye (5) longer than the snout (4) 3-6 in the head; interocular space (3) 1-6 in the eye. Pectoral fin (12) 1-5, twenty-fourth dorsal ray (9) 2-0, and ventral fin (13) 1-3 in the head. The dorsal and anal spines are stout and pungent, and increase in length backward. The anterior seventeen dorsal rays are simple, the remainder and also all the anal rays are branched. Scales finely ctenoid on the body, but cycloid on the head, anterior portion of the back, and the breast; those on the cheek are arranged in about five rows, and scales cover the bases of the posterior dorsal and anal rays. The colour is brown with a dark spot at the base of each scale together form- ing rows along the sides. The fins are dark brown, and the dorsal bears traces of rows of darker spots or lines. There is a curved dark line across the base of the pectoral with a lighter area before and behind it. Synonymy. The Director of the Queensland Museum, Mr. H. A. Longman, has lent me the holotype of Pseudochromis wildii Ogilby for comparison with the co-type of Onar nebulosum De Vis in the Australian Museum, which I re-described and figured in 1915. The two specimens are similar in all characters, and leave no doubt that P. wildii is synonymous with P. nebulosus. Their identity with P. fuscus is not certain, but they appear to agree well enough with Mtiller and Troschel's description of that species. 188 "ENDEAVOUR" SCIENTIFIC RESULTS. Localities. P. fuscus is recorded from Monte Bello Islands, West Australia. The type of P. nebulosum was obtained at Murray Island, Torres Strait, and that of P. wildii was said to have come from Moreton Bay, Queensland. Other specimens in the Australian Museum which I identify as P. fuscus are from New Britain and the Solomon Islands. PSEUDOCHROMIS, PSEUDOCHKOMIS, PURPURASCENS DC VlS. (Plate xlix.)

Canines on each side of the mandible anteriorly and one or two farther back on each side; an inner band of microscopic teeth anteriorly and a single row of larger ones which are more or less juxtaposed on each side. An angular patch of microscopic teeth on the vomer, and a rounded patch on the anterior portion of each palatine bone. FISHKS. MCCULLOCH. 189 Scales of the body rather large arid finely ctenoid, except on the nuchal region and breast where they are cycloid; they extend over the base of the caudal, but leave all the other fins naked. The lateral line rises abruptly from the shoulder and extends backward, parallel with the back to below the fifteenth dorsal ray; its tubes are simple and extend across about two-thirds of each scale. One and a half scales are present between the lateral line and the back and four rows separate the end of the upper portion of the lateral line from the lower, which extends along the middle of the sides of the caudal peduncle. Dorsal spines very slender and somewhat flexible, increasing in length backward, but the third is shorter than the eye. The anterior fourteen rays are simple, the remainder branched ; they are high and subequal in length, the twentieth (8-5 mm.) 1-8 in the head. Anal spines weak like those of the dorsal, the third longest. Pectoral and caudal fins rounded. Second ventral ray longest, not quite reaching backward to the vent; the spine is inserted a trifle in advance of the origin of the dorsal fin. Colour. Dark brown on the head and back, becoming lighter on the sides and below. A dark line crosses the middle of each scale of the anterior half of the body, and uniting with its fellows, forms striking lines which extend obliquely downward and backward through each row of scales; these largely disappear behind the middle of the body, but are traceable about the region of the lateral line. Head with dark spots and lines extending along the suborbital bone and across the operculum. An indefinite yellow band is present along the middle of each side. Dorsal fin brown, with many darker spots and curved lines between the rays which tend to form irregular horizontal bands. Anal similar to the dorsal, but with the dots less distinct. Caudal with irregular transverse rows of darker dots. Pectoral and ventral fins hyaline. Described and figured from a somewhat damaged specimen, 64 mm. long, from the New Hebrides. Identity.

An angular patch of minute teeth on the vomer, and some on the anterior portion of each palatine bone. Gill-membranes united across the isthmus, the gill- opening extending forward to below the hinder margin of the eye. Six branchiostegal rays. Gill-rakers rather slender, about ten on the lower limb of the first gill- arch, the length of those at the hinder angle equal to rather more than one-fourth the diameter of the eye. Scales of the body ctenoid, except on the nuchal region and the breast where they are cycloid. They extend over the basal portion of the caudal, but leave all the other fins naked. The lateral line rises abruptly from the shoulder and extends backward parallel with the back to below the twenty-first dorsal ray. The tubes of the first portion are broad and simple, those of the caudal peduncle more slender, and terminating in a median notch in the margin of each scale. Three rows of scales separate the anterior and posterior portions of the lateral line, and the latter extends along the middle of each side of the caudal peduncle to the hypural joint. Dorsal spines weak but pungent, increasing in length backward, but the third much shorter than the anterior ray. All the rays are branched, and they increase in length backward to the nineteenth. The margin of the fin is almost straight, rounded posteriorly, and the last ray is divided to its base. Anal similar in construction to the dorsal, its first spine microscopic. Pectoral broadly rounded, the median rays longest. Ventrals inserted slightly in advance of the vertical of the first dorsal spine, the second rays are longest, but do not nearly reach the vent when adpressed. Caudal rounded. Colour. Light yellowish-brown in formalin, e;ich scale of the upper anterior portion of the sides with a brownish spot, which, with its fellows, forms rows. A faint light-coloured stripe along the middle of each side of the body. Dorsal and anal fins dusky between the rays, especially basally; the other fins hyaline.

Affinities. P. quinquedentatus, having the anterior dorsal rays divided, belongs to the subgenus Leptoch- romis, but differs from the other species of that group, P., L., tapeinosoma Bleeker, cyanotwnia Bleeker, and melanotcenia Bleeker in having 25-26 dorsal rays instead of 21-22, and 40 instead of 30 rows of scales. It is perhaps one of several species of Pseudochromis the descriptions of which do not refer to the form of the dorsal rays, and scale-counts, etc. Localities. 13 miles south-east from Cape Capri- corn, Queensland, 12 fathoms; 29th July, 1910. 12 miles north-west of Pine Peak, Queensland, 25 fathoms; 1st August, 1910.

The lateral line rises abruptly from the shoulder and extends backward parallel with the back to below the seventeenth dorsal ray. The tubes are short and simple and do not reach the edge of the scale. Three rows of scales separate the anterior and posterior portions of the lateral line, which latter extends along the middle of each side of the caudal peduncle; each of its scales has a small median notch, and the tubes are more slender than those of the other portion and extend right across the scale. Dorsal spines very weak, the first scarcely discern- ible, the third much shorter than the anterior ray. All the rays are branched and they increase in length to the twentieth.

Described and figured from an adult male, 56 mm. long, from Masthead Island, Queensland. A female of similar size is also figured. Variation. A series of thirty specimens, 18-55 mm. long, exhibits very little variation in structural characters, but includes two very different types of colour- marking which appear to be distinctive of the two sexes. Young examples are almost uniform brown with lighter coloured pectoral, ventral and anal fins; several rows of narrow, slightly oblique and dark lines are usually present on the membrane between the rays of the dorsal fin, but they may be obscure in darker specimens. Of the two colour-variations exhibited by full grown specimens, one (female PI. li, fig. 1) is light brownish-yellow in general colour ; the dorsal fin is usually marked with dark horizontal lines as in the young, and the caudal fin has a faintly darker inframarginal border. The other (male -PI. li, fig. 2) is dark brown with the sides of the head and breast yellow ; a broad light-coloured baud extends backward from the head, and may reach the caudal peduncle or terminate below the dorsal fin ; indications of the dark lines may persist. The upper and lower portions of the caudal fin are crossed by broad light- coloured bands. Pectoral and ventral fins light-coloured. These markings vary in intensity, being distinct in some and obscure in others. The fact that I have collected both forms at three different localities, Mast- head Island, Murray Island and the New Hebrides, com- bined with their similarity in all structural details, con- vinces me that both are referable to the one species. Dissection of two specimens reveals roe in the light- coloured form, and milt in the darker example. Localities. Reef at Masthead Island, Capricorn Group, off Port Curtis, Queensland; coll.

A specimen, 210 mm. long, agrees so well with the descriptions and figures quoted above that I believe its identification as C. japonicus to be beyond doubt. Ogilby's description of his C. affinis was based upon "a specimen, 260 millim. long, obtained floating off Cape Moreton by Mr. McDonnell." This gentleman was evidently Mr. Donald Macdouald, first officer of the "Endeavour,' 1 and it was he who lent the specimen to Ogilby to be described with others collected during the operations of the trawler in Queensland waters (vide Ogilby, op. cit., pp. 85 and 135). The description con- tains several statements concerning proportions of the FISHES. MCCULLOCH. 197 snout and eye, etc., in relation to the length of the body, which are obviously incorrect, and which cast doubt upon the accuracy of other details of the description. The only specimen of C. japonicus preserved in the "P^ndeavour" collection is without data, and it differs from the description of C. affinis in being 210 instead of 260 mm. long. It tallies so well in all other details, how- ever, that it is clearly specifically identical with C. affinis, and under the circumstances, suggests that it is the actual specimen upon which the description was based, its length being misprinted as 260 mm. instead of 210. In any case, it proves the identity of C. affinis and C. japonicus. Locality. The only specimen preserved is unfor- tunately without data. C. affinis was secured off Cape Moreton, Southern Queensland. CALLIONYMUS, CALLIURICHTHYS, JAPONICUS var. SCABER, nov. CalUonymus longicaudatus Waite, Prelim. Kept. "Thetis" Exped., 1898, p. 60. Id. McCulloch, Kec. Aust. Mus. xiv, 1, 1923, p. 8 part. Four specimens in the Australian Museum, 124-218 mm. long, differ from the typical form of C. japonicus in having the upper surface of the head much more rugose. In the typical form, there are two bony bucklers, one on each side of the occiput, with smooth ridges or tubercles radiating from their centres; the median area behind the eyes is covered with smooth integument. In the var. scaber the ridges of the two lateral bucklers are very rough, and the median area behind the eyes is covered with similar bony rugosities. In all other characters the variety appears to be similar to the typical form. Locality. Lord Howe Island. CALLIONYMUS, CALLIURICHTHYS,, NASUTUS, sp. nov. (Plate Hi.) D.iv/9; A.8; P.17; V.i/5; C.10.

Head very large, depressed and heart-shaped, the snout being pointed and the opercles forming broadly rounded lobes, the free edges of which are attached just before the bases of the pectoral fins. The upper lip pro- jects well beyond the preorbital when the mouth is closed. The supraorbital margins form elevated ridges and enclose a narrow deeply-grooved interorbital space. The 200 "ENDEAVOUR" SCIENTIFIC RESULTS. occiput has bony rugose patches on each side separated by a median area of smooth skin ; a small median rugosity on the hinder margin of the occiput and a bony knob behind the postero-superior angle of each eye. Gill- openings small, superior, and separated by a space which is less than that between the outer margins of the eyes. Preopercular spines very large, with almost straight tips directed slightly outwards; each is armed with a strong basal antrorse spine, and a row of six coarse spines above, which increase in size forwards. Mouth small, the maxillary not reaching the vertical of the anterior margin of the eye. A curved band of minute teeth in the anterior part of the upper jaw and one in the lower which reaches farther backward. Body greatly compressed, the caudal peduncle much broader than deep in the middle of its length. Lateral lines united across the nape, and with the usual angular cephalic branches extending around each side of the occiput to the hinder angle of the eye and on to the cheek, and others along the preopercular margin towards the spine and across the operculum. First dorsal spine longest, but reaching little beyond the base of the anterior ray; there is no membrane behind the fourth spine. All but the last dorsal rays are simple; the first is longer than those following it, but they increase again in length posteriorly, the last being half as long again as the first. Anal rays increasing slightly in length backwards and all but the last are simple. Pectoral margin somewhat excavate above, the median rays reaching backward to the level of the third anal ray. Ventrals broadly rounded and reaching back- ward to the origin of the anal. Median caudal rays a litttle longer than the head and all but the outer ones bifurcate. Colour-marking. Very pale-coloured after preserva- tion in formalin and almost without definite markings. Two characteristic oval spots are present on each side below the lateral line, the first above the anterior portion of the anal and the other above its fifth ray; these are dark grey and enclose rings of small white spots. The first dorsal is marked with a network of grey lines enclosing round light spots; there appear to be darker areas at the tip of each spine between which the mem- brane bears a narrow white border. The soft dorsal is FISHES. MCCULLOCH. 201 marked with about eight narrow longitudinal grey lines. The anal has a black submarginal longitudinal stripe. Caudal with oblique grey lines on the membrane of the upper half and irregular rows of dots below. Pectorals and ventrals with obscure grey dots. Described from a male specimen, 149 mm. long, which is the largest of five examples preserved in the "Endeavour" collection. Variation. The other four are females and show less colour-marking, the lateral spots and black anal stripe being wanting. The anterior dorsal is darker than in the male and the marking consists of indefinite light spots on a blackish ground-colour. A young example, 63 mm. long, in the Australian Museum collection from Port Denison, Queensland, is much more definitely marked than the larger specimen but the markings are similarly disposed and they agree with those described and figured by Richardson. The young specimen has only four strong barbs on the inner edge of the pre- opercular spine, but these vary from six to ten in number in the larger ones. Status. C. lelcheri was regarded as the young of C. longicaudatus ( = C. japonicus} by Giiiither, but it is altogether different from that species. The head is much larger, being more instead of much less than one- third of the length to the hypural joint as in C. japonicus, and the preopercular spine is armed with very coarse barbs instead of fine denticles. The interorbital space of belcheri is a narrow groove instead of a bony ridge as in japonicus. Locality. 4-20 miles N.E. of Gloucester Head, Queensland, 19-35 fathoms; 2nd August, 1910.

Head smooth above, with or without an obscure rugose area on each side of the occiput. Preopercular spine not curved upwards at the tip, its inner edge with about ten small serrations, the outer with a strong antrorse spine near its base. Upper lip covered by the preorbital when the mouth is closed. Maxillary extend- ing backward a little beyond the vertical of the nostril, which is placed a little in advance of the eye. A baud of villiform teeth in each jaw. Gill-opening exposed, mid- way between the hinder margin of the eye and the upper base of the pectoral. All the dorsal spines are filamentous, the third and fourth reaching backward almost to the base of the tail. The second dorsal is elevated, and all its rays are bifid ; the last is divided to its base, and each branch is bifur- cate. Most of the anal rays are simple, only the two branches of the last being bifurcate. Upper pectoral rays slightly longer than the second, the ninth and tenth rays longest and almost reaching the vertical of the fourth anal ray; all but the outer rays are bifurcate. Ventrals large, reaching beyond the base of the second anal ray; the inner ray is so deeply divided as almost to appear as two. Caudal large and rounded, most of its rays bifurcate. Lateral line originating in advance of the gill-opening; it curves inwards towards the back above the pectoral fin, and extends backward on the dorsal rather than on the lateral surface. Colour-marking. Head and body rather obscurely marbled above, the markings enclosing some lighter spots ; an obscure darker band crosses the nape, and there are indications of others on the back. Lower parts white. First dorsal grey, the membrane profusely ornamented with fine lines enclosing lighter coloured stripes and spots, many of which are sinuous or somewhat angular in form ; the membrane is blackish near the first spine. Second dorsal with many fine parallel lines crossing it obliquely, some of which coalesce to form broad dark angular markings and enclose incomplete ocelli. Outer half of anal blackish, with some indistinct lines and spots; basal portion white. Caudal with tAvo broad dark cross-bauds, and many narrow longitudinal stripes; the membrane between the lower rays is dusky, with small darker spots. Ventrals dusky, with irregular bars across the rays, and numbers of small dark spots. Pectorals with a few grey spots. FISHES. MCCULLOCH. 203 Described and figured from a specimen, 210 mm. long, from off Cape Capricorn, Queensland ; 13 fathoms. Variation. A series of four males and three females, 173-210 mm. long, shows that the structural features described above are very constant, though the filamentous spines of the dorsal fin are somewhat shorter in females than in males. The colour marking of the body and fins varies considerably, and some specimens are much lighter than others. There are six broad dark cross- bands on the back between the nape and the caudal peduncle. The first dorsal may be ornamented with many linear markings or with small rings, or with a combination of the two; the oblique lines on the second dorsal of the holotype are wanting in some specimens, in which the fin bears many dark brown and somewhat nebulous markings. Similarly the longitudinal stripes of the caudal may be indistinct, and the dusky membrane between the lower rays may be either plain or may bear many dark-coloured ocelli. The dark part of the anal also, may bear numerous darker ocellit'orm spots and bars or be almost uniformly dusky. Localities.

CALLIOXYMUS LIMICEPS rar. SUBL;EVIS, nor. Two specimens, 182 mm. long, differ from all others of the species in the collection in lacking the granular rugosities on the upper surface of the cranium and supra- orbital ridges. In one this area is almost entirely smooth and covered by skin ; the other has smooth bony ridges radiating from a point on each side of the occiput which are most strongly developed on the left side, and a smaller one on the median line posteriorly. Both specimens are males, and have the first and second dorsal spines fila- mentous; these are marked with the usual grey annuli, but there is no black spot on the third spine as in examples of the typical form. The anal fin is largely black with a light margin, the basal portion being light- coloured only posteriorly; in the typical form the fin is light-coloured with a broad dusky or blackish border. The differences between these two specimens and a series of the typical limiceps are so striking and so con- sistent that they might well be regarded as of specific value, but the fact that both were secured in hauls which included the true limiceps, and their great similarity to that species in all but the characters noted above leads to the belief that they are merely exceptional variations.

Lateral line curving downward to above the middle of the pectoral, and then rising slightly and extending back- ward above the middle of the sides. No anal papilla. First dorsal spine inserted above the base of the upper pectoral ray; it is short, subequal in length to the second, and not nearly reaching the second dorsal when adpressed. Anterior ray much longer than the spine but shorter than the last, which does not reach backward to the hypural joint ; all the rays are simple except the last, which is divided to its base, and each branch is bifurcated.

Upper surface closely covered with brown markings which coalesce to enclose many light irregularly shaped spots; on the head these markings tend to form small darker spots. First dorsal black, lighter at the base anteriorly. Rays of the second dorsal with numerous brown spots and there are some indefinite markings on the membrane between them. Anal almost colourless. Caudal and ventrals with irregular brown spots, and some paler ones are present on the upper half of the pectoral. Described and figured from a specimen 125 mm. long, which is apparently a female. This is preserved in the collection of the Queensland Museum, and I am indebted to the Director, Mr. H. A. Longman, for the loan of it to redescribe and figure here. It is entered in the register as "1.2473. Callionymus, FISHES. MCCULLOCH. 207 Moreton Bay, donated J. D. Ogilby," and the entry is in Ogilby's handwriting. The type of C. macdonaldi was said to have been preserved in the collection of the Amateur Fishermen's Association of Queensland, but no specimen can be found therein which corresponds to the description of that species. The specimen here described tallies with Ogilby's description and measurements, and there is every reason to believe it is his holotype. Affinities. C. macdonaldi is closely related to C. calcaratus, from which it differs principally in having the occiput rugose, and in its colouration. CALLIONYMUS OCELLIGEXA *p. nor. (Plate Iv, fig. 1.)

Caudal elongate, its upper and lower rays simple, the others bifurcate. Colour-marking. Almost colourless after preserva* tion in formalin, with traces of a few brown markings on the upper half of the body, dorsal fins, and bases of the pectorals and caudal, disposed as is shown iu the accompanying figure. When first received, the head and body were rose-pink with orange spots and bars ; the most striking of these was one below the postero-inferior angle of the eye, a saddle-shaped mark across the middle of the back with a round spot before it, and several small spots on the caudal peduncle. A yellowish-brown spot on the upper base of the pectoral; the rest of the fin rose-pink. Membrane of the first dorsal orange, the spines white. A blackish-brown spot behind the first spine, a similar one on the second spine but lower than the first, and traces of others behind the third and fourth spines. The second dorsal was marked with broad oblique bars alternately orange and white, the orange ones partly corresponding with the rays. Blackish bars descended obliquely backward and downward from the tips of each ray. Caudal rays white; the membrane orange above, white below. Anal rose-pink. Ventrals white. Described from a unique example, 123 mm. long. Affinities. This species is very close to CaUiouynms pliasis Gtinther, from which it differs chiefly in its delicate coloration. Two small specimens of that species in the "Endeavour" collection have definite mark- ings as figured by Gtinther, whereas those of C. apricus are scarcely traceable on the body, being distinct only on the dorsal fins. The dorsal spines of C. apricus are longer than those of C, phasis, and the pectoral fins have twenty-three instead of twenty rays, but in all other structural characters the two species appear quite similar.

Head, body and fins entirely covered in loose, flabby skin, which almost entirely conceals the characters beneath it. Head globose, with a few open pores around the upper and lower jaws; a number of minute papillae on the under surface of the mandible. Anterior nostril in a short tube; posterior a simple opening in advance of the eye. Interorbital narrow, sub-equal to the width of the eye; its width is greatly increased by the expan- sions of the ocular margins, which form a broad inter- ocular space. Upper jaw projecting beyond the lower; the maxillary is broad and somewhat rounded posteriorly and reaches to below the vertical of the hinder margin of the eye. Both jaws broadly rounded anteriorly and each bearing a broad band of villiform teeth, those of the preruaxillaries being separated at the symphysis. Palate toothless.

Gill-openings broad, extending forward as far as the base of the pectorals and separated by a broad, flat interspace. Body very broad anteriorly, compressed towards the caudal peduncle. It is highest at the origin of the dorsal fin, behind which it decreases rapidly. The lateral line is indicated only by a raised ridge on the shoulder region. Vent about twice as far from the insertions of the ventrals as from the first anal ray; it is provided with a prominent post-anal papilla. All the fins are so completely enveloped in thick fleshy skin that their rays can be counted only when this is removed. The first dorsal originates a little in advance of the end of the opercular lobe. Its margin is rounded and the median spines are longest, but their tips are lost in the membrane and their length cannot be deter- mined. A distinct dip in the margin of the fin dis- tinguishes the first from the second dorsal. The greater number of the dorsal rays are bifurcate and the last is united to the caudal peduncle by membrane. The anal commences well behind the origin of the second dorsal and is of a similar form to that fin. Pectoral broad and reaching beyond the vertical of the first anal ray. Seventh ray longest and the median ones are bifurcate. Ventrals inserted behind the anterior base of the pectoral and reaching about two-thirds of their distance to the vent. They consist of a single spine and three rays, all of which are very closely united within a. thick membrane. Caudal rounded, its rays branched. Colour. Uniformly whitish in preservative.

A Report on the Flatfishes (Heterosomata) collected by the F.I.S. "Endeavour," with a Synopsis of the Flatfishes of Australia and a Revision of the Subfamily Rhombosoleinse. BY J. R. NORMAN. (Figures 1-15.) FLATFISHES. NORM AX. 219 INTRODUCTION. THE Flatfishes collected by the F.I.S. "Endeavour" and included in this report number about 250, and repre- sent about 30 species, of which six are described as new to science. Some of the specimens were obtained in the seas of southern and south-western Australia, but the bulk of the collection was taken off the coasts of Queensland and northern New South Wales. In addition to the "Endeavour" collections, I have studied all the Australian material preserved in the collection of the British Museum (Natural History), a number of dupli- cate specimens provided by the Australian Museum, and a small collection of Flatfishes from South Australia kindly placed at my disposal by the authorities of the South Australian Museum. In addition to the report on the "Endeavour" speci- mens, I have included a synopsis of all the known Hetero- somata of Australia, with keys to the genera and species. With the exception of two or three species known only from the original descriptions of the older ichthyologists, the types of which have not yet been re-examined, I have been able to identify all the Australian species. The synonymy and known distribution is given, and, where necessary, a re-description has also been included. No attempt has been made to make the synonymy complete for every species, but I have endeavoured to include all the more important Australian references. Finally, I have included a complete revision of the subfamily Rhombosoleinse, which is almost entirely con- fined to the waters of Australia and New Zealand. 1 This subfamily presents several particularly interesting features, of which the following are the more important: the form of the nasal organs, and their evolution within the group; the evolution of many sole-like characters within the group, which provides an interesting example 1 In connection with this revision I am greatly indebted to Mr. G. Archey, of the Canterbury Museum, Christchurch, and to the authorities of the Dominion Museum, Wellington, for New Zealand material. 220 "ENDEAVOUR" SCIENTIFIC RESULTS. of parallelism ; and finally, the ambicoloration and reversal of certain examples of the genus Rhombosolea, with the associated variations towards symmetry shown by the pelvic fins. I take this opportunity of offering my thanks to the late Allan R. McCulloch and the Director of the Aus- tralian Museum for their kindness in entrusting me with this investigation, and for providing me with an excellent series of additional specimens, and notes and illustra- tions of others concerning which I was in doubt; and to Mr. E. R. Waite, for his assistance in providing me with South Australian material, and for generously placing in my hands the notes on this group which had been already made by him. Finally, I have to thank Mr. C. Tate Regan, F.R.S., for the valuable advice which he has given me during the preparation of this report. The scheme of classification adopted is that published by Mr. Regan in 1910. 2 ARTIFICIAL KEY TO THE FAMILIES AXD SUBFAMILIES OF HETEROSOMATA REPRESENTED IN AUSTRALIA. I.

Five of the examples of this species obtained by the "Endeavour" (group A in table below) differ from the rest of the Australian specimens which I have studied (group B) in having generally a somewhat larger eye, and fewer and shorter gill-rakers. Examination of typical examples of P. arsius from East African and Indian Seas (group C) shows that the number of gill- rakers ranges from 8 to 13, and that the size of the eye is variable, as in most Flatfishes. The specimens forming group A were taken in some- what deeper water (19 to 35 fathoms) than those of group B. They do not seem to present sufficient differences to warrant their separation as a distinct species or subspecies, and may be regarded as a race of P. arsius. GROUP A. GROUP B. GROUP C.

Gill-rakers rather long and slender, mostly smooth ; 10 on lower part of anterior arch. 84 scales in a longitudinal series above lateral line. Dorsal 64. Anal 53. Chocolate-brown; body with a number of irregularly disposed oval or round annular markings, variable in size, each containing a more or less central black spot; head with a few black spots, but without annular markings; vertical tins flecked and speckled with black. Hab. Moreton Bay, Queensland. Known only from the type (142 mm.) in the Queens- land Museum. 7 6 Two examples from St. Vincent Gulf, South Australia examined by me do not differ in any way from specimens taken on the East Coast of Australia. Steindachner's (Sitzber. K. Ak. Wiss., Ivi, Abt. 1, 1867, p. 318) record of this species from Cape York is probably incorrect. 7 1 am indebted to the Director of the Queensland Museum for an illustration of the type specimen. 240 "ENDEAVOUR SCIENTIFIC RESULTS. 2.

Regan's diagnosis of this subfamily (i.e., p. 495), the members of which appear to form a natural and w r ell-marked group, must be modified somewhat to in- clude certain more primitive genera which seem to belong to it. Unfortunately the material at my disposal is insufficient to enable me to investigate the osteological characters of these genera. In Pelotretis, one of the most generalised forms, the anterior end of the dorsal fin is situated immediately behind the nasal organ of the blind side as in the Pleu- ronectinae; in Azygopus the first ray lies above the posterior nostril ; in the remaining genera the fin extends forward on the snout above the nasal organ. The jaws are almost symmetrical in Pelotretis and Azygopus, and rather more strongly developed on the ocular side in Psammodiscus ; in the other genera the mouth is markedly asymmetrical, the jaws on the blind side being strongly curved. The dentition is always more strongly developed on the blind side, and the jaws of the ocular side are devoid of teeth in all the more specialised genera. The form and position of the nasal organs is of some interest, since this character is considered to be of some importance in the classification of the Heterosomata. In the Pleuronectid subfamilies Pleuronectinae and Samarinae, and throughout the family Bothidae, the nasal organ of the blind side has accompanied or followed the eye in its migration, and is situated nearly on the edge of the head; whereas, in the Soleidae and Cynoglossidae the two nasal organs are symmetrical in position. In the subfamily Rhombosoleinae, we find the left nasal organ nearly on the edge of the head in Pelotretis, and some- what nearer to the edge of the head than is that of the ocular side in Azygopus and Rhomltosolea; but in the remaining genera the nasal organs are almost symmet- rical. All those genera with symmetrical nasal organs also agree in possessing comparatively small eyes, and 258 'ENDEAVOUR SCIENTIFIC RESULTS. in this respect resemble the Soleidse and Cynoglossidae. The symmetrical position of the nasal organs in these flatfishes appears to be correlated with the size of the eyes, since the migration of a small eye would occasion much less disturbance of the anterior region of the head than would that of a larger eye. 7 F G Fig. 8.

(F) Rhombosolea plebeia. (G) PeltorhampJius novce-zeelandia;. In the dextral Pleuronectinae and in the Samarinae the olfactory laminae rim parallel to one another, and there is no median rachis. This arrangement is quite different from that exhibited by the Paralichthodidae, the Bothidae and the Soleoidea, in which the olfactory laminae are arranged transversely to or radiating from a median rachis. Among the Khombosoleiuae, Ammo- FLATFISHES. NORMAN. 259 trctis (Fig. 8 D, 8 E), Peltorhamplms (Fig. 8 G), and Rhombosolea (Fig. 8 F), exhibit the typical Pleuronectine arrangement, but in Psammodiscus, Pclotrctis (Fig. 8 A), and Azygopus (Fig. 8 B), the laminae are arranged in pinnate form, with an elon- gate central rachis. In both the species of Colistium the laminae are arranged in pinnate form, but radiate from a very short rachis (Fig. 8 C) ; this condition appears to be intermediate between the two types mentioned above. The conclusion is that the median rachis has been lost within the group Rhonibosoleinae, and that those genera which exhibit the Pleuronectine arrangement are not on that account to be regarded as related to the Pleurouectinae. The family Paralichthodidse was erected by Regan 9 for ParaUchthodes algoensis from South Africa, which differs from the Bothidae in having the eyes on the right side, and from the PleurouectidaB in the arrangement of the olfactory laminae, which radiate from a median rachis. This character appears to be of less importance than it was thought to be, and perhaps Paraliclithodes should be included in the subfamily Pleurouectinae. The more specialised genera of the subfamily Rhombosoleiuae, i.e. Ammotretis, Peltorhamphus and Colistium, exhibit a certain general resemblance to the members of the family Soleidae. This resemblance, which is most marked in the last genus, is shown in the general form of the body, the shape of the head, particularly its praeorbital part, the small eyes, the symmetrical nasal organs, the strongly curved jaws of the blind side, the absence of teeth in those of the ocular side, and the extension of the dorsal fin to the end of the snout. The development of membraneous folds on the blind side of the vertical fin-rays, the modification of many of the scales on the blind side of the head to form filamentous processes, and the fringed lower lip, are other Soleid features. These Sole-like characters have evidently evolved within the subfamily, and do not indicate relationship to the Soleidae. The small eyes and barbel- like processes on the head are probably related to nocturnal habits; the shape of the anterior region of the "Ann.
