Nearly allied to II. violaeea, but much less spinose. Carapace 

 much dilated behind, smooth, with the exception of a few tuber- 

 culiform eminences which exist on the gastric region, on the 

 branchial region, and along the posterior border. Lateral borders 

 unarmed. Orbits limited externally by a strong spine. Internal 

 orbital angle rounded. Eront formed of two rather long pointed 

 scarcely divergent cornua. Anterior legs of the male short and 

 smooth. Ambulatory legs short and stout. [Jf.-JB.] 



Bass' Straits. 



Genus Paeamitheax, Milne-Edwards. 

 Carapace sub-triangular, rather convex, and more or less 

 tubercular and spinose. Rostral spines rather long, and 

 divergent from their base. Orbits large, with the upper margin 

 projecting, with two deep fissures ; lower margin usually 

 incomplete or widely emarginate. Basal joint of the external 

 antennae large and broad, with two spines at its distal extremity, 

 flagellum excluded from the orbit by the enlargement of the 

 basal joint. Anterior legs in the male large ; wrist with a ridge 

 crossing obliquely its outer surface, or simply tuberculated ; 

 hands rather compressed, fingers acute.
