(13) the antero-lafceral borders are armed with five slender spiiii- 

 form teeth not including tlie outer orbital angle, and the denticles 

 of the interspaces are represented by granules or arc quite inconspicu- 

 ous : 



(4) the chelipeds in the male arc 3f times the length of the 

 carapace and are very slender, especially in the palm : there are 6 or 7 

 spines along the anterior border of the arm, which is a slender cylindri- 

 cal joint, and two much smaller ones in the distal fourth of the posterior 

 border: the fingers are considerably longer than the palm, are extremely 

 slender, and their opposed edges are armed with close-set fine regular 

 teeth having larger acicular teeth at fairly regular intervals — much as 

 in the Leucosine genus Arcania : 



(5) the last pair of legs, though otherwise similar to those of 

 L. rotundatus, have the basal joints, up to and including the carpus, 

 slender, sub-cylindrical, and, in fact, hardly stouter than the correspond- 

 ing joint of the other legs. 



In other respects this species agrees with L. rotundatus. 



In the Indian Museum are five specimens — from the Andaman Sea 

 15 fms., from off the Madras coast, 33 fms., and from otf the Konkan 

 coast, 5G-58 fms. 



In the type specimen the carapace is 8 millim. long and 9 millim. 

 broad.

Carapace transverse, broad, moderately convex, with smooth un- 

 broken surface. 



The front proper projects slightly beyond the rather ill-defined 

 inner supra-orbital angles, and is either broadly bilobed or cut into four 

 shallow lobes : its breadth is about a fourth the greatest breadth of the 

 carapace. 



Antero-lateral borders moderately oblique and arched, about the 

 same length as the postero-lateral, cut into 7 rather irregular lobes 

 (including the outer orbital angles). 



The orbit, which has little or no dorsal inclination, has two notches 

 in its upper border ; the lower border crenulate. The antennules fold 

 almost transversely. 



Basal antenna-joint as long as broad, rather slender ; the flagellum, 

 which is of moderate length, stands in the orbital hiatus.
