Body and chelipeds covered with a hairy tomentum : carapace, chelipeds, 

 6th abdominal tergum and dorsal surface of telson covered with sharp discrete 

 miliary tubercles, which on the chelipeds tend to be spiniform and squamiform 

 and on the 6th abdominal tergum to be squamiform : the other abdominal terga 

 are pitted, but not rough or granular. 



Rostrum more than half the length of the rest of the carapace, with two 

 pairs of lateral spines. 



On the carapace at the base of the rostrum is a pair of large spines 

 similar to and in the same transverse line with the post-antenna! spines and 

 behind them a pair of small spines, while direrging from the base of the rostrum 

 are two rows of spinules, enclosing between them a small median tubercle and 

 then converging. Behind the very distinct cervical groove the carapace is 

 faintly carinated in the middle line. 



The abdominal pleura are, as usual, very distinctly marked off from their 

 terga: the 1st has its anterior angle produced to a tooth and its posterior angle 

 spiniform ; the 2nd 5th are all produced vertically to needle-like spines and 

 have a spine (sometimes also 1 or 2 spinules) on their anterior border ; the 6th 

 has, as usual, its posterior angle produced to a spine. 



The telson and caudal swimmerets agree with those of N. Steward except 

 in the important particular that the exopodite is not transversely fissured. 



The appendages differ from those of N. Stewarti only in having a few 

 additional spinules on the merus and carpus of the large chelipeds. 



Colours in life variable : blood-red with milk-white eyes (egomet) : pale 

 orange, with broadish white stripe on abdominal terga and posterior part of 

 carapace, antennal bases colourless, hairs on dactyli of last 4 pairs of thoracic 

 legs crimson, cornea opalescent (Anderson). 



In the largest male the length of the rostrum is 14 millim., of the carapace 

 26 millim., of the abdomen 44 millim. 



Arabian Sea, 865-880, 891, 922, 931, 947 fathoms. 



As usual, the antennal flagella exceed the length of the whole body and 

 there are 2 arthrobranchiae on the somite that carries the external maxillipeds.
