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 
edges 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, Andamans and Persian Gulf.
