British Amphipoda of the Tribe Hype- —rudea and the Families Orchestide and some Lysianasside. BY ‘Canon NORMAN, M.A., D.C.L., LU.D., F.R.S., Ere. 126 (anon A. M. Norman on British Amphipoda. British Amphipoda of the Tribe Wyperiidea and the Familves Orchestiide and some Lysianasside. By Canon NorMAN, M.A., D.C.L., LL.D., F.K.S., &e. I pPuRPOSE in these notes to revise the species of British Amphipoda, and at the same time give an account of the Amphipoda procured during the North Atlantic Expeditions of the Porcupine,’ ‘ Valorous,’ ‘ Knight Errant,’ and ‘ Triton.’ The records of the larger number of the captures of these expeditions will fall under the British species, but in those instances where the species are not members of our fauna, that which relates to them will be enclosed in brackets. The study of this group of Crustacea has been beset with difficulty, and in consequence of inadequate descriptions and illustrations old records of species must, in some instances, be received with caution. The publication of the splendid work of Professor G. O. Sars has supplied the student with most perfect descriptions and illustrations of the Amphipoda of Norway, which include by far the greater part of those known in our own fauna. If the critic is sometimes inclined to think that occasionally there are to be found in that work divergences described as specific which he would rather regard as varietal, after all it is a mere matter of opinion, and the author has at any rate directed our attention to modifica- tions of character which are worthy of study. In Sars’s work we recognize a standard authority, and the arrangement there set forth will here be followed. I have only given references to such authors and papers as especially throw light upon the species and their more im- portant synonymy. By way of shortening the references to the most frequently quoted authors, the following numbers will be employed. In those cases where the work was included in the list of works and papers on Isopoda lately given by me in the ‘Annals’ in my paper on “ British Isopoda Chelifera ” Canon A. M. Norman on British Amphipoda. 127 (Ann. & Mag. Nat. Hist. ser. 7, vol. ii. 1899, p. 317) I have here repeated the same prefix number as was there used :— (1) Bare and Westwoop.—‘ History of British Sessile- eyed Crustacea.’ 1861-9.

With respect to localities given, specimens are in my own collection from all habitats by whomsoever collected which precede the indication Mus. Nor. As at my death my col- lections will be deposited in the Brit. Mus. it will be known where types and specimens thus indicated can be examined in case of doubt attaching to species. As regards all other habitats given, the authority for them is that of the carcino- Jogists whose name is added. ~ In the case of those whose names will thus most frequently occur, I shall employ, for brevity’s sake, their initials as follows :— A. M. N.—A. M. Norway. Db. R.—Davip Roperrson. The localities are taken from his two papers on the Amphipoda and I[sopoda of the Firth of Clyde. (Trans. Nat. Hist. Soc.

With respect to the Crus- tacea of the district of Liverpool and the Isle of Man, I have depended on his ‘ Revision of the Amphipoda of the L.M.B.C. District,’ as being the corrected list. Most of Mr. Walker’s papers are published in the Trans. Liverpool Biol]. Assoc.; others will be referred to; but one should be here mentioned as it does not embrace any descriptions of species, but contains a good list of Channel Island A:phipods : “ Report on the Schizopoda, Cumacea, Isopoda, and Amphipoda of the Channel Islands,” by A.

As I pointed out in my Shetland Report of 1868, Lestri- gonus exulans and Lestrigonus Kinahani of Bate and West- Canon A. M. Norman on British Amphipoda. 129 wood are different stages of development of the male of this species. Bovallius regards Hyperia Latreille’, M.-Edw., as a distinct species ; but I agree with Sars in considering that the differences indicated are insufficient for specific distinc- tion, and are in a great measure dependent on the ages of the individuals examined. Yet, further, [ am unable to hold the Flyperia spinigera, Bovallius, as entitled to specific rank. The chief characters assigned are the spination of the two pairs of gnathopods and the form of the uropods. With respect to the gnathopods, I find that in young specimens of ff, galba the spines are sparingly developed, in middle-sized individuals they become more numerous; in large examples I find them, as in 7. spinigera (Bovallius, /.c. pl. x. figs. 34-36), encircling the extremities of the carpus of the gnathopods and well developed at the dorsal corners. The other points Bovallius especially emphasizes are the short branches of the last uropods. Now in the male sex the branches of the last uropods are always shorter than are those of the female (com- pare Sars, pl. ii. fig. us and pl. ii. fig. 1 us) ; and it is a male which is the subject of Bovallius’s figures. Should other authors disagree with my views in this matter, the female specimens of H. galba taken by me at Birturbuy Bay and the one taken off Valentia by the ‘ Porcupine’ are, from the character of their gnathopods, to be referred to H. spinigera. The Cancer medusarum of Miiller’s ‘ Prodromus’ was applied by O. Fabricius, in his ‘ Fauna Greenlandica,’ under the name Oniscus medusarum, to H. galba, and he has been followed by many authors. The Metoecus medusarum (Fabr.), Kroyer and other authors, is Hyperoche taurtformis (Bate & Westwood*). Lastly, Bovallius, Hansen, and Sars now consider the specific name medusarum (Cancer medusarum, Miiller) to belong te Hyperia spinipes of Boeck. Miiller applied the specific name to the animal described by Strém, and they doubtless think that weight must be attached to Strém’s description of the first two pairs of legs as “ hirsute and fluffy, truncated at the apex.” Hyperta medusaru (Miller) thus considered, of which the H. spinipes, Boe becomes a synonym, has not yet been found in our se; Talitrus cyanew, Sabine, is indeed regarded as a synonym . H., medusarum (=spinipes), but what the Hyperia cyanec of Bate and Westwood (vol. 11. p. 521) may be it seems * I first found this species in Shetland, and soon afterwards T. Edward procured it at Banff, and sent a specimen to me and another to Bate. I recorded the specimens I had seen in my Shetland report as Metoecus medusarum, Kroyer; Bate aud Westwood did not recognize Edward’s specimen as a known form, and described it as Hyperta tauriformis, a name which now stands. Ann. & Mag. N. Hist. Ser. 7. Vol. v. 9 130 Canon A. M. Norman on British Amphipoda. impossible to say.

Indeed Fr. Miiller has iescribed just such a difference in the posterior perseopods in his Hyperoche Martinezit, in which species these legs are prehensile in the young (as in H. prehensilis) and simple in the adult (as in H tauriformis).

This species is stated by Bovallius to be “ one of the largest of all the Amphipoda, measuring 30-42 millim.” The ‘ Por- cupine’ specimen is only 5 millim. long. Nevertheless, in most essential points, such as general character, the gnatho- pods, the structure and proportional lengths of the perazopods, &c., it agrees with £. Sayana. The lower antennze have the penultimate joint shorter in proportion to the last, and the telson is not quite so long as the basal joint of the last uropods. Bovallius lays stress upon this last character as specific throughout the.genus; but age may easily make a difference in it. In form the telson corresponds to that of LZ. Sayana. [Lanceola Murrayt, n. sp. First gnathopods with a group of about six slender spines on the posterior lobes of the meral joint; carpus, as usual, somewhat cup-shaped, distal breadth only slightly exceeding ereatest length, the extremity set round with slender spines ‘ 136 Canon A.

Second gnathopods with carpus and manus subequal in length, the length of neither exceeding two and a half times the breadth, each widest at their junction with the other, the former widening slightly distally to receive the latter; carpus with two or three small sete on anterior border and two distal setee ; hand tapering from the base to the extremity, where it is just wide enough to receive the nail; anterior margin with three spines and two distal ones ; posterior margin minutely serrulated throughout, with three slender spines about the middle and two distal spines; nail nearly straight, one-third as long as the hand, with finely serrated edge. First pereopods with the hand longer than the wrist, inner margin of each with five or six small spines at about equal distance from each other ; outer margin naked; nail long and slender, about one-fourth the length of the hand. Hinder pereeopods with the hand somewhat longer than the wrist; the curved dactylus and its sheath as usual in the genus. Telson equals two-thirds the length of the basal joint of the last uropods ; these latter with the branches narrowly lanceo- late, the branches of the second pair still narrower. This appears to differ from all described species. The first gnathopods in their less expanded wrist and propor- tionately longer hand differ from most species, but approach Bovallius’s figure of L. felina (if the hand were a little longer in that species) ; the second gnathopods are most like those of L. Sayana. Bovallius does not mention or figure in any species the serration of the margin of hand and finger in this gnathopod, and Lanceola Loveni is the only species in which serration of margin of first gnathopods is recorded. The telson and uropods are nearly as in L. serrata. L. pacifica, Stebbing (‘Challenger’), comes nearest to L. Murrayi as regards the gnathopods, but the telson and uropods are quite different.

In drawing up the specific characters of C. borealis to distin - guish it from other species, Bovallius writes :—“ As the specific character given by Bate and Westwood is applicable to several of the known Vibilie, the diagnosis here is taken from the generic characters of the authors compared with the drawing.” The brief diagnosis of the two species is as follows :— The head is not Reuse a. The pereional segments are dorsally smooth. aa. The fifth and sixth pairs of pereipoda are scarcely longer than the third and fourth pairs. aaa, The femora of the first and second pairs of pereiopoda (?.e. the gnatho- pods) are narrow. J.

Boeck confused the two British species of Hyale, and his figures of the entire animal of his Hyale Nilsson, and of the second gnathopod of the male, “ undoubtedly,” as Sars says, represent H. Lubbockiana. Della Vaile, with Stebbing’s and Sars’s clear definitions of the two species before him, actually makes the H. Lub- bockiana of Sars a synonym of his H. pontica, Rathke, which he makes =H. Nilssonz, Rathke, and keeps H. Lubbockiana of Bate and Stebbing as a species distinct from that of Sars ! A glance with even a hand-lens at the propodos of the pereopods of the true H. Lubbock.ana is sufficient at once to recognize the species on account of the two remarkable large serrated spines with which it is armed. ‘These spines are shown in Bate and Westwood’s figure &, in Stebbing’s fig. 2c, in Sars’s fig. 2, p. 7, and are even sufficiently indi- cated in Boeck’s small figure of the entire animal of his ‘““ H.

Woolacombe Sands, near Ilfracombe, North Devon (Stebbing): Mus. Nor. Saunter Sands, North Devon (Sted- bing). Distrib. Mouth of the Gironde, France ( Chevreuz). Undoubtedly the two preceding species belong to the same genus. That described by Stebbing was placed by him in the genus Zalorchestia. Chevreux finding the gnathopods of Orchestia Deshayesti in their general character corresponded with those of O. drito, removed the former species to Ta/or- chestia, and in this he has been confirmed by Stebbing. This allocation of the forms I cannot but regard as mistaken. To take Stebbing’s characters of two closely-allied genera :— Talorchestia. First gnathopods subchelate in the male, simple in the female; second gnathopods strongly subchelate in the male. Orchestoidea. First gnathopods simple in the male and female ; second gnathopods strongly subchelate in male, I am at a loss to understand how the first gnathopod male of Tulorchestia brito and Orchestia Deshayesit can be called subchelate. ‘his expression implies a palm against which the finger can close. Where is such a palm in these gnathopods ? There is a tubercle near the extremity of the hand, but if the gnathopod possesses any grasping power I take it that it would be by the approximation of this tubercle with another which is situated on the wrist ; but if this is so it would make the limb not subchelate but complexly subchelate. Exa- Canon A.M. Norman on British Amphipoda. 141 mining my North Atlantic allied forms I find Yalorchestia longtcornis (Say) and Talorchestia meyalophthalmus (Bate) from N.H. America (received under these names from S. I. Smith) to be true Talorchestie, in which the males have the first gnathopods subchelate and similar in structure to those of Orchestia, and thus quite different from the two species we are now considering. From Cadiz I have examples of Orchestoidea Fischerit (M.-Edwards) given me by Signor Bolivar under that name. In this species, as in those which I here call Orchestotdea Deshayesit and Orchestotdea brito, there is a close correspondence in the character of the first gnatlio- pod male, which is not subchelate, for the end of the hand is not expanded to receive the impact of the finger, but both the hand and the wrist bear a tubercle on the margin. ‘These tubercles may prove general throughout the genus; but whether they exist in the type Orchestovdea tuberculata, Nicolet, I have no means of ascertaining. It is a question whether the two genera ought to be maintained. It is not necessary to go beyond Stebbing’s species in the paper re- ferred to, where in Talorchestia nove-hollandie, Stebbing, we have a characteristic species of Talorchestia, in T. Deshayesit what I take to be an Orchestoidea, and in T. tridentata, Stebbing, an intermediate form, but one which, if the genera are to be kept distinct, must be retained in Tulorchestia. Fam. IJ.

Della Valle makes it clear, in my opinion, that the above species cannot be the Lystanassa Coste, H. Milne-Hdwards. That species is too imperfectly described and figured to be recognizable; but it can scarcely be our northern species, as here understood—first, because the third segment of the meta- some is not produced in hook-like form; second/y, because it was found among seaweeds at Naples; and Della Valle has not met with anything like our northern Lystanassa at Naples. He thinks it possible that M.-Edwards’s species may be the same as that which he has himself described under the name Lysianassa bispinosa. * Judging by the telson, the figures of the entire animal and of the urosome cannot have been taken from this species.

Since the date of this publication the species has been frequently named in Mr. Walker’s papers as Lystanax longi- cornis (Lucas), which, however, was an erroneous assignment of the form, as he has subsequently stated. I have consider- able doubts as to the specific distinction of this form from L. septentrionalis, since specimens occur apparently inter- mediate with only a small spine point on the hinder margin of the third segment of the metasome, instead of the large upturned process of typical L. septentrionalis. flab, This seems to be a much more abundant form on our coasts than L. septentrionalis.

Though rare, found by Sars in several places on the south and west coasts of Norway and as far north as Hammerfest in Finmark. It is not improbable that the Lystanassa atlantica, Bate and Westwood, may be the male of Ambasia Danielssent, the ereater length of the filaments of the antenne being a cha- racter distinctive of the male sex. The remarkable character of the first joint of the antennules, the form of the head, the structure of the gnathopods, all closely agree with Ambasia. It is true that the telson is described as “squamous and simple ;” but Mr. Walker *, who has carefully examined the type in the British Museum, says that it is not so, but “ cleft to the base, without lateral spines, but with a terminal spine in a deep notch in each division.” If we read ‘deeply cleft” instead of ‘ cleft to the base”’ we have in Mr. Walker’s words an accurate description of the telson of Ambasta; and to complete the identity we learn further from Mr. Walker that “the third pleon-segment has the hinder angle acute and shortly recurved, but without a sinus.” . * Mr. Walker has done excellent service in the examination of Spence Bate’s specimens.

(Report ‘Challenger’ Crustacea, p. 664.) [Cyclocaris faroensis, sp.n. (PI. VI. figs. 5-15.) The form of the head, the general character of the antenne, of the gnathopods and pereopods, of all the coxe, of the dorsal impression of the first segment of the urosome, and of uropods and telson show remarkable resemblance to Cyclo- carts tahitensis, Stebbing, the type and only previously known species of a very marked genus. So remarkable is the resem- blance, that the differences seem scarcely varietal; but I hesitate to unite a form found in the Faroe Channel with one from so distant a locality as Tahiti. The cephalon has a similar concavity between the bases of the two pairs of antenne as in C. tahdtensis, and similarly leaves the base of the lower pair fully exposed to view. The upper antenne or antennules have the peduncle shorter than the cephalon ; the flagellum twelve-jointed, the first of these joints is fully as long as the cephalon, the distal lower corner of this and of the four following joints is furnished with long slender spines: the secondary appendage is composed of six articulations, of which the first is the longest ; it reaches to the seventh joint of the flagellum. The lower antenne have the peduncle short, the last two joints of the peduncle subequal, and the flagellum consists of twenty-two articulations. No eyes are visible. The remarkable mandible (fig. 5) closely corresponds with that of the type species. The jist maxille (fig. 6) have the basal lobe narrowed almost to a point below, whence it swells out into a nearly semicircular form, furnished on the inner margin with short stiff setee, which are verticillately plumed; the masticatory lobe is elongated and narrowed to the extremity, furnished with long flexuous spines, bearing a tooth on the side, and also with slender sete: the palp is narrow, the last joint arcuate, and terminating in three teeth tipped with spine- points; of these the central is the longest; outside these at the outer corner is a small short spine and a small seta, and on the hinder margin another and larger seta. The second maville (fig. 7) have the outer lobe much longer than the inner, the latter is margined with two distinct Canon A.M. Norman on British Amphipoaa. 198 rows of sete; the sete in one of these rows are verticillately plumose, in the other simply plumose. The basal lobe of the mawilliped (fig. 8) widens distally and the extremity is rather oblique and flexuous; a row of sete is situated on the middle of the lobe; the masticatory lobe is remarkable for its great breadth and widely rounded extremity, the inner margin is faintly crenulated, the outer and distal margins are set round with simple sete at nearly _equal intervals ; the palp is stout, its terminal nail strong, the antepenultimate joint just overtops the masticatory lobe. The gnathopods have the coxe small and almost entirely concealed by the overlying coxa of the first perezopod. Both pairs of gnathopods (figs. 9 & 10) closely resemble those of C. tahitensts, but the first pair are much more stoutly built than in that species. The pereopods with their coxe (figs. 11 & 12, coxe of second and third pair) are in close agreement with those of the type. A comparison of fig. 13 of the last pereopod with Stebbing’s figure of the same limb in C. tahztensis shows the remarkable resemblance, seen even in the hinder margin of the basos, which in the lower portion is slightly concave and devoid of the serrations which are present in the upper portion of the margin. The third segment of the metasome has the hinder corner of the epimera slightly produced and pointed (fig. 14). The first segment of the urosome has a dorsal sinus. The second uropods are longer than the first, but do not reach to more than half the length of the rami of the largely developed last pair, which have their rami fully twice as long as their peduncle: the outer branch is two-jointed; its inner margin bears four or five small spinules, and under a high power the margin itself is seen to be delicately serrulated. The telson (fig. 15) is narrow, very long and produced, and cleft almost to the base; it extends beyond the extremities of the first and second uropods. Length 19 millim. Two specimens taken by Sir John Murray in the ‘ Triton’ Expedition of 1882, Stat. 8, Faroe Channel, lat. 60° 18! N., long. 6° 15! W., in 640 fathoms, temperature 30° Fahr. The features which distinguish this species from the type are chiefly the more robust character of the first gnathopods and the form of the hinder margin of the third segment of the metasome. | 199 Canon A.

Robertson wrote of this species in his ‘* Second Contribution ” :—‘‘ This seems to be one of the sea-scavengers. A fisherman brought to me portions of the crab Lithodes maia from his bait-creel, and every part of it was crowded with this species clustered on the top of each other. All the flesh was as perfectly cleaned off the body, legs, and claws of the crab as if the parts had been bleached on the shore for a twelvemonth. The number of these Amphipods was quite surprising, and I had a six-ounce bottle filled with them. So far as I have seen, they are all of the same species. ‘The wonder is why they remained on the empty shell of the crab after having cleaned out all the soft parts, unless, like the boa-constrictor after a great feast, they require a long time to digest it. .... It is a curious fact that the Amphipoda met with at these great banquets, so far as I have seen, are mostly of one species. Sometimes they are exclusively Zryphosa nanoides, or at other times wholly Lafystius sturionis, Orchemenella nana (=cilrata), or Callisoma crenatum. Whether each species has its own particular prey, or whether the weaker species give way to the stronger, cannot easily be proved.” It is not always so, for I may mention that at Falmouth on a dead fish in a crab- pot I found Orchomene humilis and Socarnes erythrophthalmus Canon A. M. Norman on British Amphipoda. 204 associated in thousands of each species enjoying their dinner in mutual respect. At Shetland I obtained Tryphosa nanoides in great abundance on a dead fish. As Orchemenella ciliata, G. O. Sars, has been shown by J. Bonnier to be a synonym of Tryphosa nana (Kroyer), Boeck, and Sars has acquiesced in this view, and as Tryphosa nana was made by Boeck the type of his genus Tryphosa, it is necessary that both generic and specific names employed by Sars should give way to those which are earlier. 34*. ?

Is Anonyx minutus, Bate & Westwood, this species ? I do not think it can be, and am inclined to believe that the Amphipod figured and described by them was a young male of Orchomene humilis, Costa, which species is found abun- dantly at Polperro and Plymouth, whence Bate had specimens of “ Anonyx minutus.” Both figures and description accord with O. humilis, except the description of the posterior pereo- poda, which description, however, does not accurately apply to any allied form known to me. The only other record of the occurrence of the species in our fauna is given thus by Mr. T. Scott :— This species is reported from Minard (Loch Fyne), where it was collected in 1870 by Murray.” It must be observed that Sir J. Murray does not study the Amphi- pods, and we do not know the authority who identified the species. 35. Tryphosa pinguis (Boeck). 1860, Anonyx pinguis, Boeck, Forh. ved de Skand.

Héringii, but basal joint of upper less stout; flagellum of eighteen articula- tions, the first nearly equal in length to the basal joint of the peduncle, accessory appendages of seven articulations, first only slightly longer than the second; flagellum of lower antennee with twenty-five articulations; both pairs furnished with calceole. Gnathopods of both pairs of the usual form in the genus and very like those of J. Sarsi; first slender, the hand slightly shorter than the wrist; the second with hand obovate, somewhat wider than the wrist, finger well developed. Last uropods with long rami and fully twice the length of the telson, which bears three pairs of lateral spines. In all that has been said this species closely resembles the characters of the genus Tryphosella; but on examining the mouth-organs it is seen that instead of the epistoma over- hanging the upper lip, the upper lip projects beyond the epistome as in Orchemenopsis or as in Tryphosa nana, which in this respect differs from other species which Sars assigns to that genus. Indeed, these allied genera seem constituted on very unsatisfactory characters, and I cannot but think that an amalgamation is desirable. Length 6 millim. ; The angular projection of the sides of the cephalon, the character of the epistoma, the rounded hind corner of the third segment of the metasome, and the form of the first segment of the urosome distinguish this species from allies.

Four examples are in the Copenhagen Museum which were taken on as many different occasions in the Green- land seas in 15-100 fathoms. The ‘ Porcupine’ specimen agrees closely with Hansen’s description and figures. ‘The figure shows a dorsal sinus on the fourth segment of the metasome; there is no such sinus in my specimen, and Hansen in his description says ‘“ Seg- mentum quartum caude dorso integro, non carinato.” Of the third segment Hansen writes, “ Angulus infero-posterior segmenti tertil caudz rotundatus incisura perparva supra angulum in margine posteriore adest.”” I should have rather described it as a spine-point placed rather above the angle (Sars’s figure of the same segment in Calliopius Rathkei gives an idea of it, the spine-point, however, being a little * oxtoros, divided, ovpa, tail, I have adopted the form Schisturella, because Schistura is in use, as is also Sevssurella, 209 Canon A.

The marked characteristics of this species are the general structure of the antennal organs, the remarkable epimera of the first segment of the mesosome, and the abso- lutely divided telson. The first gnathopods have the hand shorter than the wrist, oblong, very slightly tapering, the palm very oblique, defined by a cluster of sete, and bearing on its edge a remarkably delicate plate cut into serrations, the serrations very fine and not densely placed *; nail strong, bearing a secondary tooth near the apex as in the genus Haplonyx. But the character which first caught my eye as distinguishing the species from any other Lysianid known to me, though figured by Hansen, is not mentioned in his description. From the end of the first long joint of the fila- ment of the antennules there is projected a very long and slender spine (see Hansen, fig. 6a), which reaches to the middle of the fifth following articulation.

(fully three quarters of an inch) in length. The eyes are lageniform, and, being large and black, give a marked character to the species.” Mr. Scott has kindly allowed me to see the specimens and given me one of them. The occurrence of this truly Arctic species so far south is of great interest. In 1869 I recorded this species as having been found by me in Shetland; but this was subsequently found to be a mistake, the specimens proving to be large examples of Zryphosa nanoides, Lilljeborg. Not only are these specimens interesting as an addition to our fauna, but also on account of their size and the time of the year (February) in which they occurred. Sars gives as dimensions “ usual length of adult female 18 mm.; maximum length of Arctic specimen 40 mm.” The largest specimen I have in my collection is 43 mm. (Kara Sea). Now I have large numbers of examples of what I take to be this species procured by myself on the Norwegian and Finmarkian coasts an the summer months ; but none of these exceed 11 mm., which is the measurement which Sars gives for Anonyx Lilljeborgit. Is the life of the Anonyzx limited to a year, and do all the females after they have produced their young in the spring months then die? Herr I. Sparre Schneider has suggested that this is the case with certain Amphipods. As regards these small summer-captured specimens of Anonyz, are they the young of A. nugaw, and is also Anonyx Lilljeborgii the equivalent of those young? Iam disposed to think so, My specimens vary to some extent, but in the main agree very fairly with Sars’s description and figures of A. Lilljeborgit. The characters of this form are mostly comparative, and, as has already been pointed out by Stebbing (Amphipoda ‘ Willem Barents’), are such as might naturally be expected as results of a younger stage. One point Sars mentions as though it were important :—“ The two anterior pairs of pereiopoda with a very conspicuous obtuse denticle at the end of the propodos immediately below the dactylus.” ‘I'his denticle is very 211 Canon A. M. Norman on British Amphipoda. conspicuous in small specimens, but apparently does not increase in size with the growth of the rest of the limb; it thus becomes less and less conspicuous as the animal is more developed, but if looked for it can be found in the largest examples of A. nugaz.

With the exception of the character of the eyes, this Haplonyx (I cannot call it a species) is indistinguishable from H. similis, G. O. Sars. I assign to it a specimen pro- cured by Sir J. Murray in the ‘ Triton,’ 1882, in the Faroe Channel, in a tow-net sunk to 570 fathoms, because I can see no trace of eyes in the spirit-preserved specimen, and the depth makes it probable that the specimen belonged here rather than to H. s¢milis. It has been found by Prof. Sars in the Hardanger and Trondhjem Fiords, Norway, in about 150 fathoms. ] [Genus 23. ALIBROTUS, Milne-Edwards. [Alibrotus littoralis (Kroyer). 1844.
