downwards from the epibranchial teeth. The posterior margin 

 of the peristoma has a median ronnded projection, notched on each 

 side. The chelipedes are very unequal, in some specimens the right, 

 in others the left being the larger ; meropodites with their dorsal 

 edges sharply rugose ; carpopodites also rugose with their inner 

 margins armed in the usual manner with a sharp tooth, beneath 

 which is a smaller one ; the propodite of the larger claw is extreme- 

 ly convex, smooth, granulated and near its extremity canaliculate, 

 punctate, and with the granulations passing into minute sharp 

 spinules ; the dactylopodite is similarly marked and is in contact 

 with the extremity only of the produced portion of the penultimate 

 joint in the larger claw. 



The ambulatory legs are thin, slender, and rugose.

Carapace convex from behind forwards and transversely ; front 

 broad, especially at base, sinuous, produced, with a sharp chisel-like 

 free edge ; anterior boundary of the epistoma almost straight, send- 

 ing forwards a small median process which indents the sub-frontal 

 lobe, scarcely taking any share in the formation of the inter-anten- 

 nulary septum ; posterior edge divided by two distinct notches into 

 three rounded lobes, the median one of which is largest, lateral lobes 

 internally rounded but passing almost straight outwards to form 

 the anterior boundaries of the orifices for the egress of the water 

 that has served for respiration. Post-frontal crest interrupted, 

 divided into two external larger and two internal slightly ad- 

 vanced smaller portions which together equal in width one of the 

 former ; an tero -lateral margin armed with an epibranchial tooth
