Closely resembles A. tomentosus, from which it is distinguished by 

 the following characters : — 



The carapace is subglobular: the regions are very distinctly 

 delimited and areolated, the areolae being strongly convex and often 

 uniformly granular. 



The outer angles of the front form distinct little lobules : the 

 fissure in the lower orbital margin, just below the outer angle, is indis- 

 tinct. 



The granules on the wrist are more numerous. 



The more convex carapace and the more numerous and more convex 

 areolae, at once distinguish this species. 



In the Indian Museum are 32 specimens from the Andamans, 

 Ceylon up to 34 fms., Persian Gulf, Pedro shoal, and Mergui (besides 

 13 from Hongkong and 1 from Samoa). 



The Indian specimens, especially those from deep water, have the 

 lobules of the carapace more convex than those from Hongkong.

" The carapace is very convex, covered with a short brown pubes- 

 cence, and provided with a series of remarkable granulated lobes. 

 The frontal margin is granulated and four-lobed, the rounded prominent 

 submedian lobes separated by a narrow median fissure, the outer lobes 

 of small size. The antero-lateral margin has four prominent, sub- 

 equal, granulated or subspinose lobes, while the postero-lateral margin 

 is smooth and deeply excavated ; the upper orbital margin is granulated 

 and has two well-marked fissures. The granulated lobes on the carapace 

 are arranged as follows : — On the anterior gastric region, behind the 

 front, two pairs, of which the posterior is much larger ; on the posterior 

 gastric region three lobules, one median and anterior, two posterior ; 

 on each protogastric or lateral gastric region a peculiar Vl/-shaped 

 lobule ; on the cardiac region two lobules which are slightly excavated 

 in the centre ; on the branchial region three lobules, anterior, postero- 

 external (which is the largest of the three), and a postero- internal 

 one placed external to and between the posterior gastric and cardiac 

 lobules." 



" The right cheliped is slightly larger than the left in both sexes ;
