to be removed before the sculpture and texture of the carapace can be 

 properly made out. 



On the denuded carapace the lobules are numerous, are arranged 

 in series which appear to radiate from the cardiac region, and are 

 somewhat indistinct quite posteriorly, but are elsewhere distinct, moder- 

 ately convex, and separated by broad smooth furrows. 



Front obliquely deflexed, rather sliarply bilobed. Supra-orbital 

 margin moderately tumid, narrow, cut by two fissures and separated 

 from the lower edge of the orbit by a fissure. Anterolateral borders 

 four-festooned, the first and last lobes much smaller than the others. 

 Postero-lateral borders shorter than the antero-lateral, moderately 

 concave. 



Exposed (dorsal) surfaces of the chelipeds and legs granular and 

 shaggy: the wrist and upper surface of the hand are also subuodular, 

 but the corresponding joints of the legs are but indistinctly grooved. 

 Lower outer surface of hand with granules in lines that are not so 

 definite as usual. Fingers blunt-pointed, slightly hollowed at tip. 



Basal antennal joint broad : it falls short of the inner angle of the 

 orbit. 



Colours in spirit yellow, fingers dark brown with white tips: in 

 some specimens faint orange-red spots exist on some of the lobules of 

 the carapace. 



Carapace markedly more convex in the female than in the male. 



In the Indian Museum are 30 specimens from Malacca Str., A tula- 

 mans, Meigui, Ceylon, and Persian Gulf.

This species, if my identification be correct, differs from Actsea 

 ruppellii, which it closely resembles, in the following characters : — 



(1) the carapace and legs are not shaggy, and though they bear 

 some hairs these do not in any way conceal the texture of the carapace : 



(2) the lobulation is quite absent from the posterior third of the 

 carapace; and elsewhere though quite distinguishable, is extremely 

 faint, owing to the fineness of the grooves : 



(3) the entire surface of the carapace — grooves as well as lobules 

 — is covered with crisp granules, which are largest in the middle of the 

 branchial regions : 



(4) the lobulation of the antero-lateral borders, though distinguish- 

 able, is extremely indistinct, especially in the case of the firstrlobe:
