tlie anterior edge of their greatly compressed meropodite closely spinate, and 

 the posterior edges of that joint and the ischinm closely spiniibte ; their last 

 three joints have the edges smooth, except for a few small jointed spinules at 

 the base of the posterior border of the dactylus. The last pair of legs have 

 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 fms., a male and a female ; 370-419 fms., 3 males 

 and 3 females. Bay of Bengal, off Coromandel Coast, 14-5-250 fms., a male and 

 a female. Gulf of Manar, off Colombo, 142-400 fms., 2 yoimg males. 



Dimensions of carapace of a full-grown specimen 41 millim. long, 36 

 millim. broad. 



The gills are fourteen in number on either side, exclusive of a quite rudi- 

 mentary posterior arthrobranch to the penultimate pair of legs. 



Subgenus ParomoJa. 

 Ilomolaprofundorinn, Alcock and Anderson, Plate I, fig. 2. 



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 

 fi'om 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 

 hoUow for the retracted eye, an antennal s]3ine 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 con- 

 spicuous 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 spines and a strong terminal spine on 

 the anterior border of the merus, a few articulating spinules at the far end of
