Differs from L. Beaumontii in the followinfr particulars only : — 



(1) .the carapace is still more nearly square : 



(2) there are 2 spines on the antero- lateral borders but none at the 

 outer orbital angles : 



(3) the inner border of the ischium and arm of the chelipeds is 

 serrated, and the meropodites of the legs are armed with spines. 



(4) the colouration is yellow, with a large purplish-brown horse- 

 shoe behind the front, and with sinuous markings of the same colour on 

 the lateral subfrontal and suborbital i-egions of the carapace : the 

 greater part of the antennal flagella is of the same pui'plish-brown 

 colour. 



In the Indian Museum is a single sijecimen from the Andamans : 

 the carapace is 4 millim. long and 5 millim. broad.

Carapace subquadrilateral, with the antero-lateral angles acute and 

 the lateral borders posteriorly convergent, a good deal broader than 

 long, moderately convex, the regions but faintly indicated. 



The front and orbits occupy the whole anterior border of the 

 carapace : the front is square cut, laminar, and obliquely deflexed, and 

 takes up between a third and a fourth of the anterior border of the 

 carapace, the rest being tsiken up by the trench-like oi-bits. 



Eyestalks long and slender : the antennules fold quite transversely 

 beneath the front : the antennse have a short basal joint and a slender 

 flagellum of good length, standing in the orbital hiatus.
