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

 siderably broader than in the last species. 



In the accompanying table measurements of this species and of a sin-

NOTOSTOMUS EGBUSTUS, Sp. nOV. 



(Plate VII, Fig. 2.) 



This species is closely allied to JVT, gibbosus A. Milne-Edwards, but is 

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

 de Crustac6s, by its much larger eyes, much shorter and distally un- 

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

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

 longer than in rcbustus, 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 robustiis 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-
