278 REPORT 1868. 



into a rounded lobe of considerable size, fringed with plumose setae ; 

 carpus antero-distally bearing a circlet of strong spines ; propodos much 

 flattened and expanded. Third segment of pleon having the posterior 

 margin waved, and produced backwards at the infero-posteal angle into 

 an acute hastate point. Telson cleft almost to the base, having a row 

 of spine-like hairs down middle of each portion, reaching to the middle 

 of the branches of the last uropods, which are much longer than the 

 preceding pairs. Balta Sound and St. Magnus Bay, Shetland (A. M. N) ; 

 Kirkwall Bay, Orkney (Mr. D. Robertson); Aberdeenshire (Mr. Dawson).

 Gammarid. p. 85 ; Bate, Cat. Crust. Amphip. Brit. Mus. p. 94, agrees 

 with A. Icevigata in having the infero-posteal angle of the third seg- 

 ment of the pleon produced backwards into a spine-like point, but 

 differs in that the meros of the last pereiopods has no posterior lobe. 

 I have dredged it in the Sound of Skye. The Ainpelisca Belliana of Bate 

 appears to be referable to this species.]

(Ediceros parvimanus, Bate & Westwood. The type specimens Were procured 

 in 1861, in 70-90 fathoms, sixty miles east of Shetland ; and I have since 

 found it in other directions on the Haaf, and very abundantly on the 

 soft muddy ground of St. Magnus Bay. 



cequicornis, n. sp. Rostrum extending beyond the first joint of upper 

 antennse. Upper antennas having the three joints of the peduncle of 

 nearly equal length, each more slender than preceding ; filament equal 

 the length of last two joints of peduncle, composed of five long articu- 

 lations. Lower antennae slender but short; peduncle exceeding the 

 length of that of superior by nearly the last joint, which is equal in 

 length to the penultimate ; filament very slender, 4-5 jointed, equal in 

 length to the last joint of peduncle. First gnathopods with wrists in- 

 feriorly produced into a wide rounded lobe reaching forwards to the 

 commencement of the palm ; hand obovate, widest in the centre where 

 the palm commences, which is very oblique ; finger slender, simple, as 

 long as palm. Second gnathopods very like the first, but the hand 

 slightly larger, and rather more elongated. All the pereiopods with very 

 long and nearly straight nails, which about equal the propodos in length ; 

 propodos much longer than carpus. Penultimate pereiopods with a row 

 of setae down the middle of the basos. Last pereiopods with the basos 

 small, elongated, pear-shaped, equally produced anteally and posteally ; 

 both margins with small cilia, the hinder margin also crenated ; the last 

 four joints all greatly produced, and each longer than the basos ; the 

 whole limb very long. Length about one-fourth of an inch. A single 

 specimen from St. Magnus Bay, in 30-60 fathoms, 1867. (E. cequicornis 

 comes near to (E. brevicalcar of Goes ; but his figures represent the 

 hands narrower in proportion to the wrists than in the present species, 

 and there are other slight points of difference. He does not describe or 

 figure the last pereiopods, which are the most characteristic organs in 

 (E. cequicornis.
