Generic character. Superior antennae longer than the in- 

 ferior, having a secondary appendage. Second pair of gnatho- 

 poda very large in the male. Posterior pair of pleopoda having 

 the internal ramus rudimentary, the outer very long. Telsou 

 double. 



THE eyes in this genus are round, and not very large. 

 The superior antennae are furnished with a secondary 

 appendage. The inferior antennae are scarcely longer 

 than the peduncle of the superior. The second pair of 

 legs are furnished, in the male at least, with a very large 

 hand; and the finger generally impinges somewhat within 

 the margin of the palm. The walking legs are nearly of 

 the same length ; and the three posterior pairs have fre- 

 quently the fingers directed backwards. The posterior 

 pair of the caudal appendages have the branches very 

 unequal ; the outer one being very long, the inner very 

 short, and frequently rudimentary, as in the typical 

 species. The central tail-piece is double.
