the sides : its I'egions well defined : the transverse and oblique ridges 

 are salient, and the surface betsveen the latter is coarsely reticulate. 



Front deep and almost vertically deflexed, overhangiiig the cpistorae 

 and much concealing the anteunules, its free edge crenate. 



Length of the epistome one-third or more of its greatest breadth. 

 The tooth at the inner angle of the orbit is blunt. 



Chelipeds in the male hardly longer than the carapace, shorter iu 

 the female : inner border of iscliium and arm strongly spinate, and 

 there are one or two less acute spines at the far end of the outer border 

 of the arm : wrist with fine scattered tubercles on its upper surface, and 

 with its inner angle produced to form a talon-shaped spine : palm nearly 

 as high as long, its outer surface sculptured, its upper border culminat- 

 ing iu a tooth : the fingers have very broad rounded tips, and the 

 length of the dactylus iu the male is nearly twice the length of the 

 upper border of the palm. 



Of the legs the 1st pair are very decidedly the shortest and the 

 3rd pair the longest, the latter being about twice the length of the 

 carapace : the 4th pair ax'e longer than the first by a dactylus, 

 and shorter than the 2nd by about two-thirds of a dactylus. Only 

 in the last pair of legs does the breadth of the merus approach 

 half the length of the same joint : the far end of the upper box'der of 

 the merus is spine-like and there are usually 2 or 3 spines at the far 

 end of the lower border. 



In tlie Indian Museum are 18 specimens from the Laccadives, the 

 Andamans, the Coromandel coast, and Ceylon. The carapace of a 

 large specimen is 64 millim. long and 6S millim. broad.
