Differs from Garpilodes tristis Dana in the following more conspicu- 

 ous particulars : — 



(1) the surface of the carapace is of a shiny smoothness, except 

 for some irregular pitting on the lobules of the anterior portion : 



(2) the gastric region is subdivided into five longitudinal lobules 

 (as in all the following species ) by incisions running almost parallel 

 with the limbs of the £ shaped median incision : 



(3) the chelipeds have the upper and outer surface of the wrist 

 nodular and of the hand granular, and the upper surface of the cor- 

 responding joints and merus of the legs nodular : 



(4) the colour in spirit is light yellowish. 

 A single specimen from Mergui. 



It appears to me very doubtful whether this species is really 

 distinct from G. venosus.

Included in the Indian fauna on the authority of Dr. J. R. 

 Henderson : there are no specimens in the Indian Museum referable to 

 this species, unless (as, indeed, I believe) G. stimpsoni is synonymous. 



From Milne Edwards' figures this species differs from G, stimpsoni 

 in having the chelipeds and legs perfectly smooth. 



6. Garpilodes pediger, n. sp. 



Allied to G. venosus and stimpsoni, from which it differs in having 

 the whole of the carapace mapped out in lobules. 



Most closely allied to G. ruber A. M. Edw., from which it conspicu- 

 ously differs in the form of the male chelipeds. 



Carapace extremely convex in both directions, its surface, like that 

 of the appendages, being perfectly smooth to the naked eye though 

 very finely granular under the lens : it is symmetrically and minutely 

 subdivided by fine lines into very many little-convex and rather angular- 

 outlined lobules. The antero-latoral borders are rather deeply four- 

 lobed, the prominence of the outer angle of the orbit forming a small 

 fifth lobule. 



The chelipeds in the adult male are close upon twice the length of 

 the carapace and have a very strong tooth on the inner upper border of
