The figure of this fine species exhibited on plate V. of the Illustrations of 

 the Zoology of the Imestigatar is a female. The adult male is here figured.

Closely allied to IpMcnlus, but differing in several important characters and 

 in the whole form of the carapace. The appendages are as densely tomentose 

 as in Iphicidns, but the carapace is covered with a finer and sparser tomentum 

 which does not quite conceal the texture of the surface. 



The carapace is circular and globular, with its margins coarsely spinate, and 

 its surface vesiculous : the intestinal region is very distinctly isolated, but the 

 other regions are almost lost in the general convexity of the carapace. 



The front is narrow : in one species it projects as a distinct snout, in the 

 other the angle of the afferent branchial canal can be seen beyond it in a dorsal 

 view, but the whole mouth can never be seen beyond it as it can in Iphiculus. 



The orbits are obliquely elongate and completely conceal the eyes : two 

 distinct fissures are plainly visible in the emarginate roof, besides a fissure in the 

 lower part, and there is a gap at the inner canthus where the basal joint of the 

 antenna — the flagellum of which is large — stands. The antennules fold very 

 obliquely. There is a space of varying width between the edge of the orbit 

 and the edge of the buccal cavern. 



The buccal cavern is rather elongate-triangular, and the merus of the 

 external maxillipeds is half the length of the ischium measured along the inner 

 border. 



The chelipeds are from 1^ to If times the length of the carapace : the hand 

 is short, cylindrical with the base inflated, or is subglobular, but not nearly so 

 swollen as in Iphiculus : the fingers are slender, much longer than the hand 

 and somewhat hooked ; they open in an obliquely vertical plane, and the tip 

 of the mobile finger moves through the usual arc of about 75°. The legs are 

 moderately stout. 



The abdomen of the male has the 3rd, 4th and 5th segments fused : that 

 of the female has all the segments distinct.

Carapace globular, just broader than long, its surface closely covered with 

 large vesiculous granules beneath a dense fine-textured pubescence : the intes- 

 tinal region forms an independent circular swelling, bounded by a deepish
