 having the palm iiTcgular, not oliliquc ; inferior angle slightly 

 j)roduced in the form of an obtuse tooth ; dactylos nearly straight,

" Rather elongate, with the back round ; the posterior margin, from 

 the second to the fifth segments of the pleon, furnished with a 

 median dorsal spine acutely produced, the third segment having 

 the latero-posterior margin spuriously biangulated. Superior 

 antenna) reaching to the second segment of the pleon ; inferior 

 antenna) scarcely reaching beyond the peduncle of the superior. 

 Propodos of the second pair of gnathopoda veiy large, having the 

 palm oblique and ciliated, the inferior angle armed with teeth. 

 Posterior pair of pleopoda extending considerably beyond the pre- 

 ceding pair.

The difference between this animal and Oammarella hrevicaudata 

 appears to consist in the spinous character of the pleon and the length 

 of the posterior pleopoda.
