it is armed dorsally with 10-14 (commonly 11), ventrally with 7-8 (usually 7) 

 teeth, and on either side its base is buttressed by a carina which extends as far 

 as the middle of the gastric region. 



The inflexed postero-lateral angles of the carapace are produced to form a 

 slightly everted tooth. 



The spine of the 3rd abdominal tergum is very much longer than those of 

 the 4th and 5th. 



In the female the anterior lobe of the pleuron of the 1st abdominal somite 

 is intact, and the pleura of the 2nd abdominal somite are broader (fore and aft) 

 than deep : in the male the anterior border of the pleuron of the 1 st abdominal 

 somite is deeply excised with the lower or posterior angle of the notch pro- 

 nounced and usually produced, and the pleura of the 2nd somite are at least as 

 deep as broad. The telson is longer than the caudal swimmerets. 



Antennular peduncle very short, the basal joint the longest : the flagella are 

 as long as the carapace plus about half the rostrum. The antennal scale is not 

 much shorter than the carapace. 



The external maxillipeds are the stoutest of all the thoracic appendages and 

 the longest excepting the 3rd pair of legs, reaching beyond the end of the 

 antennal peduncle by more than half their terminal joint : their second segment 

 (basis-ischium-merus) is strongly arched with the convexity outwards. 



The first two pairs of legs reach to the base of the terminal joint of the 

 external maxillipeds and are very similar in form : the 1st pair differs in having 

 the exopodite foliaceous, the wrist and the palm somewhat inflated, and the 

 fingers a little shorter than those of the 2nd pair : the latter have a spine near 

 the far end of the lower border of the merus. 



The 4th and 5th pair of legs are decidedly shorter than the 3rd pair, which 

 last reach slightly beyond the tips of the 1st pair. The lower border of the 

 ischium and merus of the 3rd and 4th pairs is more or less spinous. 



In an egg-laden female the rostrum is 22'5 millim. long, the carapace 15'5 

 millim., and the abdomen 34'5 millim. In a large male the rostrum is 22 millim. 

 long, the carapace 16 millim., and the abdomen 32 millim. 



Colours in life : bright transparent red, with golden patches on the abdominal 

 pleura and last 3 pairs of thoracic legs : tail-fan colourless. Eggs purplish red. 



Found here in the Andaman Sea, in 185, 188-220, and 370-419 fathoms ; 

 in the Bay of Bengal, in 145-250, 272, 200-350, 364, 594-225, 609, 1260 and 

 1439 fathoms ; and in the Arabian Sea, near the Laccadives, in 406 fathoms. 



HoplojjJtorus loiigirostris, Spence Bate, from off Fiji, is almost certainly this 

 species.
