206 A. Alcock — Carcinologicul Fauna of India. [No. 1, 



Carapace f as long as broad, strongly convex, profusely deeply and 

 symmetrically puckered-areolate. 



Front much less than a third the greatest breadth of the carapace, 

 shaped as in A, tessellatus, but the edges of the lobes and lobules are 

 crenulate. 



Orbits and relations of antennas as in A. tessellatus, but the edges 

 of the orbits are sharply crenulate. 



Autero-lateral margin cut into three sharply crenulate granular 

 teeth — not including the orbital angle : postero-lateral margin shorter 

 than the antero-lateral, concave. 



Chelipeds a little unequal : fingers granular in the basal half or 

 more. 



Carpopodites and propodites of legs, and meropodite of last pair, 

 sharply granular as to the dorsal surface. 



Colours in spirit pink, fingers brownish. 



Carapace 135 millim. long, 18 milliin. broad. 



A single male from off the coast of Sind, 51 fms. 



129. Actumnus elegans, de Man. 

 Actumnus elegans, de Man, Journ. Linn. Soc., Zool., XXII. 1887-88, p. 47. 



Carapace and exposed surfaces of legs and chelipeds covered with 

 a thickish bright-yellow tomentum, with longer hairs on chelipeds and 

 legs and near frontal margin. 



Carapace not much more than § as long as broad, with some 

 scattered comparatively large granules, but with almost no indication of 

 regions ; convex fore and aft, slightly so from side to side. 



Front about a third the greatest breadth of the carapace, broadly 

 triangular, notched at the apex, not separated from but confluent with 

 the supra-orbital angles. There is a suture line in the lower orbital 

 margin just below the outer angle. 



Antero-lateral borders not shorter than the very concave postero- 

 lateral, armed with 7 acute spinuliform granules, in 3 pairs, with an odd 

 one between the first pair and the orbital angle. 



Chelipeds unequal : the upper and outer surfaces of wrists and 

 both hands, including a large part of the fingers closely studded with 

 conical white granules. 



In the Indian Museum are 2 specimens, one from Mergui the other 

 from Kyuk Phyu Harbour. 



This species seems to me to be better placed with Pilumnus than 

 Actumnus : it and Pilumnus scabriusculus White, seem to be very closely 

 related.
