Carapace hardly convex, decidedly broader than long, its length 

 being about four-fifths its breadth betsveen the antero-laternl ans^les, 

 deep ; the 4 post-frontal lobes prominent equal and a little rugose traiis- 

 Tersely, the rugae being sparsely tufted with hair; the cardiac and intes- 

 tinal regions very much less distinct than the gastric : some oblique 

 striations on the epibranchial regions 



Front decidedly more than half the greatest breadth of the 

 carapace, not very deep, its free margin usually but slightly sinuous. 

 Lateral borders of carapace nearly parallel, a little divergent ante- 

 riorly, without any tooth behind the acute orbital angle. 



The chelipeds differ in the sexe.s, being about If times the length
