External double palpi with the second joint of their inter- 
nal footstalk, at its internal apex, truncate-emarginate, 
palpigerous. 
Legs ten; anterior pair very thick, didactyle, unequal, with 
deflexed fingers ; other pairs simple, alike; claws com- 
pressed, their sides grooved, the extremities naked. 
Abdomen seven-jointed ; of the Mate, with the third joint 
broadest ; the last elongate-triangular, with its apex 
rounded. 
Parthenope is more nearly allied to Eurynome than to 
any other genus, (see Malacostraca Podophthalma Britan- 
nie, Tab. XVII.) ; but it is at once to be distinguished, 
by its very short antenna, entire rostrum, and unequal 
hands.
