282 Carcinological Fauna of India. 



palms of the chelipeds are elongated, tricarinated, and dentated (as in 

 Lambrus) ; fingers short. The ambulatory legs are slender, decrease 

 successively but slightly in length, and have the fourth, fifth and sixth 

 joints more or less distinctly carinated ; dactyli nearly straight.

Carapace broadly triangular, depressed : the antero-lateral margins 

 more or less laciniated, the posterior and postero-lateral margins 

 forming one strong curve, the edge of which is either unbroken or 

 shows very faint traces of crenulation : the surface of the carapace is 

 in the main smooth, but the triangular depression is a little pitted and 

 is bounded by lines of granules, the lateral lines being produced well 

 across the branchial regions. The rostrum is prominent, blunt-pointed, 

 about as long as broad, and has its edge very faintly crenulate. 



The chelipeds are considerably less than twice the length of the 

 carapace, and have massive sharply trigonal joints, with most of the 

 edges strongly cristiform ; and the fingers are massive and strongly 

 incurved as in Lambrus : in the arm, the cristiform inner and outer 

 edo-es are sharply laciniate, the latter being strongly alate, while the 

 lower edge is beaded : in the carpus the outer edge only is cristiform : 

 in the hand both the inner and outer edges are strongly cristiform and 

 laciniate, the lower edge being crenate. 



The ambulatory legs have both edges of the merus raised into 

 spiniform crests, and the upper edges of the next two joints carinate. 



In the Museum collection are numerous specimens from Palk 

 Straits, Andamansand Persian Gulf.
