It appears to me possible that this, which seems to be founded on 

 a single specimen, is only an individual variation of L. granulosa. 



Lophactsea sp. 



From Inglis I. (Andamans) a single small specimen, not agreeing 

 with any described species, which in the circumstances I forbear to 

 describe. 



It belongs to the L. cristata and semigranosa group, but has the 

 inter-regional furrows much shallower and less distinct, and the pearly 

 granules absent from all but the front part of the gastric region and 

 the lateral parts of the epibranchial region : those on the chelipeds are 

 also mucli fewer and more scattered. The legs are very hairy.

Carapace moderately broad, moderately convex in both directions, 

 with the regions well delimited and subdivided into numerous lobules, 

 the surface of which is not usually granular. 



The antero-lateral borders are sharp and crest-like, and are cut into 

 lobes (usually four in number) ; the postero-lateral borders are straight 

 and strongly convergent. 



Front about a fourth the greatest breadth of the carapace, obliquely 

 deflexed, grooved and emarginate in the middle line : orbits large, the 

 tumid edge with the three suture lines near the outer angle distinct ; 

 eyes on short thick stalks. 



Antennules folding nearly transversely, inter- antennulary septum 

 broad. Basal joint of antennae short, touching the front only at the 

 (produced) antero-internal angle ; the flagellum short (less than the 

 major diameter of the orbit), lodged in the orbital hiatus. 



Merus of the external maxillipeds with the front edge a little 

 oblique. 



Chelipeds equal in both sexes ; fingers with broad hollowed-out
