Adult male. As in the female there are paired spiniform tubercles on the 
back of the last pedigerous and first two pleon somites, while the terminal joints 
of the peraeopods are of the same proportions. Carapace fully one-third of total 
leneth of animal, less inflated than in male of inflatus and with dorsal outline more 
regular. Antero-lateral angle and pseudorostral lobes much as in inflatus. 
Only a narrow strip of first pedigerous somite exposed. 
Upper margin ot antennal groove of first to fifth pleon somites quite strongly 
spinose; fifth somite more than half as long again as wide, with a pair of spini- 
form tubereles at hinder margin; telsonie somite slightly longer than wide.

prp., first antenna, third maxilliped and peraeopods; urop., uropods with fifth pleon and telsonic 
somites (all * 86). 
Peduncle of uropod more than three-fourths as long as telsonic somite, and 
two and one-half times in length of endopod, exclusive of its terminal spine ; exopod 
about one-eighth as long as endopod and with its distal spine reaching distinetly 
beyond middle of length of latter; endopod with five short spines on inner mar- 
vin and with terminal spine one-third as long as its ramus.

The smaller males previously identified by the writer as zimmeri Calman are 
referred here. N. subinflatus is very like Calman’s species but the last-named 
differs in having the pseudorostral lobes meeting below, and in the male for a short. 
distance above also, the pleon is without spines, while the carpus of the fifth leg is
