The form and structure of the carapace is somewhat similar to 

 that of Parthenolambrus ; but the genus is distinguished from Lambrus 

 by the nature of the so-called basal antennal joint, which is relatively- 

 long, and nearly reaches to the level of the inferior orbital hiatus : the 

 fingers also are much less turned inwards. 



Key to the Indian species of the genus Parthenope. 



I. Carapace remarkably rugose or spinose : chelipeds nearly 

 of the ordinary Lambrus form, and beset with huge 

 spines : ambulatory legs strongly spin ate : — 



1. Carapace and chelipeds beset with coarse tuber- 



cles and spines : carapace about £ as long as 



broad P. horrida. 



2. Carapace and chelipeds beset with spines, which 



are sharp and laciniate on the chelipeds : cara- 

 pace only | as long as broad P. spinosissima. 



II. The whole body and all the appendages beset with delicate 

 paxilliform tubercles which unite to form a lace-work 

 or frosting : chelipeds tapering, with long slender spiny 

 fingers, nearly as long as the palm (sub-genus Partheno- 

 merus) P. efflorescens.
