The following characters distinguish this species from N. Stewart n, which 

 it otherwise closely resembles. 



The carapace and chelipeds are granular, but there are no discrete granules 

 or tubercles beneath the fur that covers the body. 



The rostrum is never less than half the length of the rest of the carapace 

 and usually has two pairs of lateral spines : sometimes there are three pairs, 

 occasionally 1- pair only. 



Behind the pair of large spines at the base of the rostrum is a second pair 

 of small spines, and between these two pairs of spines are two rows of spinules 

 diverging from the base of the rostrum and enclosing a median compressed 

 tubercle. 



The abdominal terga, from the 2nd to the 6th, are longitudinally traversed, 

 in more or less of their extent, by a low smooth carina. 



The abdominal pleura from the 2nd to the 5th are produced vertically each 

 into a needle-like spine ; and on the anterior border of the 2nd pleuron, near 

 the middle, is an antrorse spinule. 



The large chelipeds in the adult male are only as long as the body behind 

 the cervical groove, and the hand is shorter than the combined ischium and 

 merus. 



The claw-like tooth of the COXEB of the legs of the 3rd pair is particularly 

 prominent. 



The colours in life were pink, Avith a broad white longitudinal dorsal stripe. 



In an egg-laden female the length of the rostrum is 12 millim., of the 

 carapace 22'5 millim., of the abdomen 40 millim. : adult males have the same 

 dimensions. 



Arabian Sea near the Laccadives and to the northwards, at 636, 696 and 

 740 fathoms.
