lateral borders are sharply four-lobed, each lobe being rasp-like. The 

 posterolateral borders are a little concave. The posterior border is 

 formed by a row of bead-like granules, in front of which is another row 

 — broken in the middle — of larger beads. The sternum, and the under 

 s a if ace of the carapace as far as the beaded epimeral suture, are oovered 

 with vesiculous granules. 



Those surfaces of the chelipeds and legs that are exposed in repose 

 are closely and crisply granular, many of the granules being pearl-like 

 or bead-like, and those along the dorsad border being spine-like : the 

 edges of the legs, especially the upper edge, are hairy. The granules 

 on lower outer surface of hand are arranged as usual in lines. 



Fingers short, pointed, not hollow at tip. 



The basal antennal joint falls far short of the inner angle of the 

 floor of the orbit. 



Colours in spirit, white. 



In the Indian Museum are 3 specimens from off the Malabar Coast, 

 28-29 fins., one from the Persian Gulf, and one from the Andamans. 



Actsea nodulosa var. bulltfera. 



In this well-marked and very ornamental variety the lobulation of 

 the carapace — both of its surface and of its antero-lateral borders — is as 

 deeply cut, as convex, and as regular as it is in Actasa rufopunctata ; the 

 tubercles are more of one size, and have a distinct constricted base and 

 a swollen spherical pearl-like top ; the front row of pearly granules of 

 the posterior border is unbroken ; the front is more bilobed with sinuous 

 edges than four-lobed, and its edge is elegantly denticulated or beaded ; 

 and all the parts of the under surface of the body are finely granular, 

 except the sternum, which has a pitted worm-eaten look. 



Length of carapace 10 millim., breadth 14*5 millim. 



A single female from the Andamans. 



75. Actasa echinus, n. sp. 



Closely resembles Actsea nodulosa White, but has the following 

 difference : — 



(1) instead of pearly tubercles we find coarse conical tubercles or 

 tooth-like spines with denticulated tops; and on the chelipeds and 

 antero-lateral borders of the carapace are coarse serrated spines : 



(2 ) the front is broadly bilobed, the angles of the lobes being sharp : 



(3) the lobulation of the antero-lateral borders is irregular and 

 indistinct : 



(4) the legs are thin and compressed, the dorsad border of the 

 carpal and propodal joints forms a serrated crest, and the slightly
