Paeapasiphae, gen. nov. 



In external characters, and especially in the form and structure of the 

 peraeopods, this genus is very near Pasiphae) but the body is less com- 

 pressed, and the rostrum, not separated from the front of the carapax, 

 projects above or between the bases of the eye-stalks. In the three 

 species seen the front margin of the carapax below the rostrum is un- 

 armed and the lateral carinae more conspicuous than in Pasiphae and 

 differently arranged. In all the species there is a sharp carina extend- 

 ing back from the base of the antenna to the hepatic region, where it
