of the chelipeds are quite smooth, but the upper surface of the arm 

 has an incomplete longitudinal line of beading. The ambulatory legs 

 are long and particularly slender. 



In the Museum collection are specimens of males, ovigerous females 

 and young, from the Andamans and from off Ceylon.

Lambrus deflexifrons, Miers, Ann. Mag. Nat. Hist., Vol. IV. 1879, p. 21, pi. v. 

 fig. 5. Ceylon. 



This species, which is not represented in the Museum collection, 

 is described as follows by Miers : — 



" The carapace is strongly constricted beliind the orbits, with the 

 cardiac region very convex, and with an oblique but shallow sulcus on 

 the branchial regions, and is covered with closely-set small tubercles ; 

 the antero-lateral margins are unarmed ; but there are two larger 

 tubercles or small spines on the postero-lateral margins. The rostrum 

 is vertically deflexed, triangular, and granulated above. The basal 

 antennal joint is very small; the epistoma is large; the sub-hepatic 

 and pterygostomian regions are not channelled. The anterior legs have 

 the arm rounded and tuberculate above, with small spines on its 

 anterior margin ; the wrist is tuberculate ; the hand with a few 

 tubercules on its upper surface, the anterior margin armed with about 

 ten, and the posterior with four granulated spines. The under surface 

 of arm, wrist, and hand is closely granulated. The ambulatory legs are 

 smooth, and are not compressed and cristate as usual in the genus. 



The vertically deflexed rostrum and carapace, devoid of spines on 

 its surface and anterior margins, and non-compressed ambulatory legs 

 are characteristic of this species. It seems to be allied to L. gracilis, 

 Dana, a species from the Fijis, in the form of the carapace and legs ; 

 but in that species the carapace has a spine on the cardiac and each 

 branchial region, and elsewhere appears to be smooth."
