tlie north coast of Spain at 900 metres ; like the preceding, 

 it is blind *, 



An Elasmonotust , also blind, found at 106S metres off 

 Oporto is very distinct from the fom- species of this genus 

 which inhabit the American seas. A Diptychus also exists in 

 European waters J. 



Fonkyphilus norvegicus, Sars, supposed to be peculiar to 

 the northern seas, occurred, associated witli the preceding 

 species and with another unknown spinous PontopJiilus^. A 

 Macruran of the family Hippolytidaj must form a new genusH. 

 Its eyes have no corneas, and are terminated by three small 

 spines. The genus Acanthephyra., of which I have described 

 several species from the West-Indian seas, has a representa- 

 tive ^ in the abysses of the ocean off the Berlingues at 2590 

 metres. Its colour, like that of the Gnathopliausice^ is a mag- 

 nificent carmine red. A Pasiphae which the dredge brought 

 up from 900 metres presented exactly the same coloration. 

 Among the most important acquisitions made in these same 



* Galathodes rosaceus, A. M.-E. — The rosti'um is broad and lamellar, 

 and terminates anteriorly in three points, of which the median one is 

 keeled above, and the lateral ones very short. The sides of the carapace 

 are armed with four spines. The segments of the abdomen are rounded 

 above. The arm and forearm of the chelfe bear a few spines ; the hands 

 are unarmed ; the colour is rosy. 



t EIas)nonotus VaiUantii, A. M.-E. — This species is well characterized 

 by the arrangement of the gastric region, which is much elevated, and bears 

 in front two small symmetrical points dominating the rostrum. The 

 latter is short, simple, and pointed. The abdomen is keeled transversely, 

 and armed upon the tirst two segments with a median projection bearing 

 two little spines. 



X Diptychtis ruhrovitiatiis, A. M.-E. — This species differs from D. 

 nitidus by its smaller eyes, its more widened and shorter carapace, its 

 more triangular and less slender rostrum, and its stronger and more stumpy 

 chelfe. Its colour is purplish rosy, marked on the chelte with lighter 

 bands. (Brought up from a depth of UOO metres.) 



§ Pontuphilus Jdcqtieti, A. IM.-E. — The body is larger and more thick- 

 set than that of P. norvef/ictis ; its rostrum is shorter and does not reach to 

 the level of the cornepe. A single median spine exists upon the cara- 

 pace above the anterior cardiac lobe ; two other lateral spines appear in 

 tront of this. Lastly the branchial lobe also bears a spine. 



II Richardina spinicincta, A. M.-E.— The rostrum scarcely passes be- 

 yond tlie basal joints of the outer autennai : it bears twelve teeth above, 

 and tive below. The carapace bears, in front, on each side of the gastric 

 region, three small spines, and a cincture of s])icules behind the cervical 

 groove. The feet of the first two pairs are didactyle ; those of the last 

 two pairs are multiarticulate and monodactyle. 



^ Acanthcplnirii purpurea^ A. i\[.-E. — -The rostrum is slender, nearly 

 straight, and bears nine teeth on its upper and tive on its lower margin. 

 The third segment of the abdomen is armed with a median posterior 

 point directed backward. Another similar, but smaller, point e.xists on 

 tlie iifth and the sixth segment.
