The head is rostrate, shorter than the first two pereional segments. The flagellum of the 

 first pair of antenna' is a little longer than the head, and rounded anteriorly. The femora of 

 the first six pairs of pereiopoda are cylindrical; the carpi and metacarpi provided with 

 long hairs. The tibia? of the third and fourth pairs are not tumid. The fifth and sixth 

 pairs are a little longer than the third and fourth pairs. The sixth pair are the longest 

 of all. The second and third ural segments are free, not coalesced. The hinder corners 

 of the last segments are not produced. The peduncles of the uropoda are narrow, cylin- 

 drical, much longer than the rami. The telson is rounded, longer than half the peduncle 

 of the last pair of uropoda.

From the description of Milne Edwards I add the following details. 



The head carries a comparatively long rostrum, longer than half the head. The head 

 is much deeper than long. 



The eyes are elongate-ovate, large, placed vertically. 



The first pair of antennae are quite as long as the head and the first pereional 

 segment. The flagellum is thick, broadly rounded at the apex, as long as the head and 

 half the first pereional segment, provided with long hairs and some spines. 



The second pair of antenna? are filiform, a little longer than the first pair, few- 

 jointed, the last joints very short. 



The maxillipeds are provided with a rounded median lamina and two large bean- 

 shaped lateral lobes, (at the inner side are to be seen two rudimentary appendices corre- 

 sponding with the palps in the Gammarids? see Hist. nat. des Crustaces p. 72 and 

 pi. 30, fig. 2.) 



The pereion is smooth, the segments almost equal in length, the seventh a little 

 longer than the others. The epirnerals are narrow, equal. 



The first and second pairs of pereiopoda are subcheliform; the carpal process of the 

 first is shorter, that of the second longer than half the metacarpus. The tibia?, carpi, and
