For the shorter definition of this genus, see Note on Claus, 1879 (p. 492). The fuller 

 definition which Claus gives of it is to the following effect : — 



" Body Pronoe-hke, but less strongly compressed, with more rounded head, the pleon 

 bent and having its hinder section generally flexed. Antennae and mouth-organs like 

 those of Eupronoe, the latter, however, far longer and more produced. The first 

 gnathopods simple, the second complexly chelate. Laminar first joint of the third 

 perseopods broad and of oval form, that of the fourth perseopods of greater extent, 

 triangular, distally narrowed and truncate, with short longitudinal ridge. First joint of 

 the fifth perseopods of smaller extent, the appendage rudimentary, one- or two-jointed. 

 Hinder section of the pleon distinguished by the elongation of the coalesced fifth and 

 sixth segments. Last pair of uropods with very short peduncle and short, more or less 

 fin-like, rami." 



In further observations on the genus Claus says, " Both antennae have the same
