the posterior edge of their subcylindrical meropodite closely spinate 

 and have only a single terminal spine on the upper edge, the carpus has 

 a strong terminal spine on its posterior border, and the propus has a 

 salient group of spines behind the middle of its posterior border forming 

 a subcheliform stump for the serrated posterior edge of the claw-like 

 dactylus. 



Colour in life salmon-pink. 



Andaman Sea, 188-220 fathoms, a male and a female; 370-419 

 fathoms, 3 males and 3 females. Bay of Bengal, off Coromandel Coast, 

 145-250 fathoms, a male and a female. Gulf of Manar, off Colombo, 

 142-400 fathoms, 2 young males. 



Dimensions of carapace of a full-grown specimen 41 millim. long, 

 36 millim. broad. 



The gills are fourteen in number on either side, arranged as in 

 Homola harhata, exclusive of a quite rudimentary posterior arthrobranch 

 to the penultimate pair of legs.

Carapace very decidedly macruriform, deep, ovoid -triangular, 

 broadest abaft the middle of the branchial region, tapering to an acutely- 

 spiniform rostrum of which the length is about a third that of the rest 

 of the carapace. Diverging from either side of the base of the rostrum 

 is a spine of similar form and size. The only other elevations on the 

 carapace are a hepatic spine just behind the hollow for the retracted 

 eye, an antennal spine just outside the antennal base, and a blunt 

 denticle near the middle of the ill-defined lateral border. 



The gastric region is well delimited, and the linea anomurica is 

 broad conspicuous and dorsal. 



The stout cylindrical terminal joint of the eye-stalks is longer than 

 the slender basal joint, the eyes are of good size, well pigmented, and 

 hemispherical. 



The chelipeds are slender but are stouter than the legs ; the arm 

 has the outer lower border spinate and, on the upper border, a few 

 spinules and a strong terminal spine ; both the inner and the outer 

 angles of the wrist are armed with a strong spine, the fingers are much 

 shorter than the hand and have the cutting-edge entire. 



The legs are slender and subcylindrical, the 2nd and 3rd pair, 

 which are slightly longer than the first, are at least three times the 

 length of the carapace. In the first 3 pair there are a few distant
