The adult males from the Pacific have no denticle on the posterior part of 

 the lateral margin of the carapace. 



The maxillae (fig. 2a) differ considerably as to the relative size of their 

 main part and the palp from those of A'^. niicrops, the palp being nearly as long as 

 the inner margin of the lobe of third joint and about half as long again as broad. 



In immature specimens measuring 9-10 mm. in length the frontal plate 

 with the not defined rostrum is longer and anteriorly more produced than in 

 the adults, and the upper section of the eyes is considerably smaller than the 

 lower. In still smaller specimens, 6.5-7 mm. long, the frontal plate is propor- 

 tionately still longer, reaching bej'ond the eyes and with the distal third of the 

 lateral margin somewhat convex and the tip itself acuminate and acute; the 

 upper section of the eyes is much smaller than the lower, and the dorsal keel 

 on the carapace is very conspicuous, but its highest part with the anterior margin 

 more oblique than in the young of N. microps (comp. the "Siboga" paper). 



One of the largest females is 18.5 mm. long; a good-sized male is 14.5 mm., 

 but most adult specimens of both sexes are somewhat or sometimes considerably 

 smaller.
