Front gently convex beyond the orbits, finely cleft in the middle 

 line. Orbital border sharp, somewhat puckered by three sutures near 

 the outer angle. The crest-like antero-lateral border is sharp and is 

 cut into four teeth, of which the first is separated from the orbit by a 

 gap, the third and fourth are keeled, and the third strongly accuminate. 



Chelipeds equal, their surface perfectly smooth : the upper edge 

 of the arm is strongly crested, the crest at its distal end being foliace- 

 on sly expanded and deeply cleft ; wrist with a strong double tubercle 

 at its inner angle ; upper edge of hand crested, but rather coarsely ; 

 fingers large, long, pointed. 



Legs smooth : upper edge of merus carpus and propodite strongly 

 crested, the inner face of the crest with tufts of long hair ; dactylus 

 furred up to the claw. 



Colours in spirit : a bright orange-red network on a dull yellow- 

 ochre ground, fingers black. 



In the Indian Museum are two specimens from Singapore.

This species appears to differ from L. octodentatus only in having 

 the first lobe or tooth of the antero-lateral margin acute instead of 

 rounded and the outer surface of the hands granular and hairy. 



There are no specimens in the Indian Museum; and the species — 

 if it be distinct — is included in the Indian fauna on the authority of Dr. 

 J. R. Henderson.

Carapace with the regions well delimited, and having the branchial 

 regions (and to a less extent, the gastric region also) subdivided into 

 lobules which have their anterior margins sinuous and sharply under- 

 mined so as to have a semi-imbricate look. The surface of these lobules 

 is a little dented and uneven, and the grooves that separate them are 

 full of hair.
