We have but one specimen, a female, of this species. The carapax 

 is suboctagonal, or rhomboidal, with the angles truncated, the lateral 

 ones obliquely. It is broader than long, in the proportion of i : 1.07. 

 Both the antero-lateral and the postero-lateral margins are slightly 

 concave. The carapax is very convex across the middle, and there 

 is a narrow median carina extending from the front to the sharply 

 prominent and granulated cardiac tubercle. The branchial regions 

 are prominent, irregularl}- granulated about their summits, the outer 

 granules large and sharp. Front concave, minutely granulated. 

 Posterior margin nearly straight, its surface granulated. Surface 

 of the carapax, except at the points mentioned above, smooth and 

 glabrous. There is a minute spine at the summit of the pterygos- 

 tomian angle. The surface of the outer maxilli])e(ls is obsoletely 

 granulated. Chelipeds granulated, the marginal granules few. dis- 

 tant, and subspiniform ; the meros-joint more than twice as long as 

 broad. 



Dimensions of the carapax: Length, 0.28: breadth. 0.3 inch.
