the posterior margin of each segment dorsally elevated, gi^'ing 

 the animal a corrugated or iml)ricated appearance. Eyes pro- 

 minent. Superior antenna) not so long as the peduncle of the 

 interior. Inferior antenna; nearly as long as the animal ; flagel- 

 luin shorter than the last joint of the peduncle. First pair of 

 gnathopoda smaU : second large, having the cai-pus very minute ; 

 propodos as long as the cephalon and the first two segments of the 

 pereion. Two posterior pairs of pereiopoda suhequal, long. Ante- 

 penultimate pair of pleopoda having the rami sube(]ua:l ; penulti- 

 mate much shorter than the preceding, with the rami tmecjual ; 

 ultimate nidimentary, scarcely extending beyond the extremity of 

 the telson. Telson squamiform, suborbicular. 

 Length T^ths of an inch. 



Hah. Dredged at Falmouth ; St. Michael's Mount, on the beach, at 

 low water (J7y. Wehster).

" Antennaj equal. First pair of gnathopoda having the propodos 

 ovate, and less than that of the second. Second pair of gnatho- 

 poda, in the male, ha^•ing the propodos oblong-ovate, palm arcu- 

 ate, inferior margin nearly straight ; in the female, the propodos 

 is oval. Telson single, foliaceous, rounded at the apex. Dorsum 

 furnished with small tubercles. 



" Length ^^jjths of an inch. 



'' Hah. Eather rare in the bays of Bohusia, e. cj. Gullraarsfjorden, 

 and at the island called Koster, where it was taken at the depth of 

 from 120 to 130 fathoms." — Briizelius.

Body long. Antenna) short ; flageUa rudimentary; superior pair \A'ith- 

 out any secondary appendage. Coxae not so deep as the pereion. 

 Gnathopoda subchelate ; second pair having the propodos much 

 larger than that of the first. Pereiopoda subequal. Three pos- 

 terior pairs of pleopoda liaving short rami. Telson s(piamiform(?). 



The nidimentary character of the fiagella of tlie antennas, tlie 

 absence of the secondary appendage, and the shortness of the coxa) 

 are characters that separate this genus from I'odocerns ; the size 

 and form of the seccmd pair of gnathojioda distinguisli it from Coro- 

 2>li'nnii ; and the shortness of tlie anteiiii;e and relative proportions of 

 the gnathopoda separate it from Dryope and Unciola.
