Carapace ovoid and very broad, its greatest length less than two- 

 thirds its greatest breadth, its dorsal surface — like that of all the 

 surfaces of the chelipeds and legs that are exposed in repose — covered, 

 as closely and evenly as possible, with a dense short blackish felt 

 through which peep the shiny tops of very numerous large vesiculous 

 granules. This felt is not so long as to obscure the areolation of the 

 carapace which is very perfect and in bold relief, but it obscures the 

 fact that the deep-cut grooves that separate the lobules are smooth. 



The lobules — excluding those of the antero-lateral and supra- 

 orbital margins and those on the front — are 21 in number, the anterior 

 8 with the long diameter fore-and-aft, the posterior 5 with the long 

 diameter transverse. 



The front, which is vertically deflexed a,nd does not break the wide 

 even sweep of the antero-lateral borders, appears nearly equally four- 

 lobed, the outer lobe on either side being formed by the tumid supra- 

 orbital border. 



The antero-lateral borders are long and beautifully arched ; when 

 undenuded they look entire, but when denuded they are seen to be cut 

 by narrow clefts into four very shallow lobes of unequal size, — the 

 clefts being continued as grooves on to the under surface of the cara- 

 pace. The very short postero- lateral borders are extremely concave. 



The tumid supra-orbital border is cleft into lobules by two fissures 

 similar to the grooves of the carapace, and there is a third fissure at 

 the outer angle of the orbit. 



The whole under surface of the carapace, and the surfaces of the 

 sternum and external maxillipeds and abdominal terga, are covered 

 with a dense felt that obscures all the granulation that exists.
