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 spinate :— 
1. Carapace and chelipeds beset with coarse tuber¬ 
cles and spines : carapace about f as long as 
broad. P. horrida. 
2. Carapace and chelipeds beset with spines, which 
are sharp and laciniate on the chelipeds: cara¬ 
pace only f 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.
