of its length. Anterior margin most nearly resembling that of 

 E. hirsuta Sars, but the antero-lateral tooth is more prominent and 

 the serrations on the upper part of the margin (anterior margin of 

 the pseudorostral plate) point downward. On the upper surface of 

 the carapace about one-third of its length from the front margin is 

 a small, anteriorly curved tooth. 



The antennules have the second segment of the peduncle dilated, 

 its width about two-thirds of its length. The inner flagellum does 

 not nearly reach to the end of the fu'st segment of the outer. 



The first legs have the propodus distinctly longer than the carpus 

 and more than tmce as long as the dactylus. The second legs have 

 the carpus about equal to the merus and hardly longer than the pro- 

 podus and dactylus together.
