388 DISCOVERY REPORTS 



Rostrum very short, extending only to end of peduncle of antenna. Supra-orbital 

 spines large ; carapace rounded behind. Abdominal somites 1-5 without dorsal spines ; 

 somites i, 4, 5 with pleura rounded, somites 2 and 3 with long pleural spine on either 

 side. Somite 6 with small terminal dorsal spine, but no lateral or anal spines. Telson 

 narrow, shorter than uropods, with pair of small apical spines and six setae between. 



Endopod of antenna about two-thirds length of scale. Maxillule without trace of 

 palp. Maxillipede i endopod and exopod very small, the former of two segments only. 

 Legs 1-3 with endopods chelate. Legs 4 and 5 rudimentary. Pleopods absent. Uropods 

 large, with many setae. 



An older specimen of 7-8 mm. differs only in having the endopod of the antenna 

 longer, and in the presence of pleopods. 



Two specimens from Sts. 1575 and 1578 agree so nearly with those from the Atlantic 

 that they may be assumed to belong to the same species. In one of them the pleura of 

 abdominal somite i were pointed, a difference which may perhaps be specific.

Stage VI }. Length 12-2 mm. (rostrum 2-1 mm.). 



Rostrum not reaching end of peduncle of antennule, smooth. Supra-orbital spines 

 small; carapace rounded behind. Abdominal somites 1-5 without dorsal spines, but 

 each with a small procurved pleural spine. Somite 6 with small dorsal, but no lateral 

 or anal spines.
