 stouter than in the last species. The lamella of the uropods are con- 

 siderably broader than in the last species.

NOTOSTOMUS EOBUSTUS, sp. nOV. 



(Plate VII, Fig. 2.) 



This species is closely allied to N. glbhosus A. Milne-Edwards, but is 

 distinguished from it as figured in Milne-Edwards's Recueil de Figures 

 de Crustac6s, by its much larger ej^es, much shorter and distally un- 

 armed rostrum, and the strongly divergent lateral carinse of the carapax. 

 In the gibhosus the rostrum, measured from the back of the orbit, is much 

 longer than in robustus, the high dorsal crest does not extend more than 

 half the length, and the terminal portion is slender and serrate above 

 and below to the very tip; while in rohtisUis the dorsal crest extends to 

 within a short distance of the slender and unarmed tip, back of which 

 there are only three or four spiniform teeth on the under edge. In ro-
