 In this genus, which is distinguished from its nearest neighbours 

 by havnig no scale to the second antennae. Alcock discriminajtes 

 five Indian species — stczvarti Wood-Mason, carpcnieri Wood- 

 Mason, atlantica Norman, cnsirostris Alcock, and snJuiii Bate. 

 Faxon describes occidcntaUs from the neighbourhood of Aca- 

 pulco, Mexico, and identifies aaileatiis Smith and rosea Bate with, 

 the earlier ^/^'c^j-j-/;//' A. Milne-Edvvard.>. 1880. Protessor Smith 

 described the species independently, only becoming acquainted 

 with the account given by Milne-Edwards in time to add a note 

 recognizing the priority of the French author.

From the other Indian species A'- atlantica is distinguished iir 

 Major Alcock's key by combining lateral spines on the rostrum, 

 a spine on anterior margin of side-plate in second pleon-segment,. 

 with transverse suture of outer ramus of uropods. This combina- 

 tion distinguishes it also from iV. occidentalism since that is without 

 tlie lateral spine on the second segment of the pleon. N- 

 cilantica is variable in the lateral spines of the rostrmn, having 

 usually two pairs, sometimes three, occasionally one and a half. 

 In accordance with this statement by Major Alcock, out of four 

 specimens from South Africa, one has three pairs, two have twO' 

 pairs, and one has a pair and a half of these spines. Dr- Faxon 

 describes N. occidentalis as having only one pair, but adds that in 

 one young example the rostrum is armed \vith two spines on one 

 side and with one on the other side. In addition, however, to 

 other differences, a sharp median spine on the base of the telson 

 separates A', occidentalis from all the other species. 



A female specimen, carrying a few large eggs, has the left 

 cheliped 56 mm- long, but that on the right only 23 mm., its last 

 five joints being a reproduction, quite hairless, slender and white^ 

 in contrast with the adjoining orange red, strongly setose third 

 maxillipeds, which have the inner margin of the third joint 

 toothed or nodulose.
