 In this genus, which is distinguished from its nearest neighbours 

 by Iiavnig no scale to the second antennse, Alcock discriminates 

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

 Mason, atlanlica Norman, cnsirostris Alcock, and siiJnni Bate. 

 Faxon describes occidcntalis from the neighlxairhood of Aca- 

 pulco, Mexico, and identifies aciilcaiiis Smith and rosea Rate with 

 the ea.r]\er (I o-t/ss/z// A. Milne- Kd\Vcird>. 1880. Professor .Smith 

 described the species independently, only becoming acquainted 

 with the account given by IMilne-Ed wards in time to add a note 

 recognizing the priority of the French author.

From the other Indian species A'- allantica is distinguished in 

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

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

 \\ ith transverse suture of outer ramus of uropods. This combina- 

 iion distinguishes it also from A'', occidentalis, since that is without 

 tlie lateral spine on the second segment of the pleon. AT. 

 cilantica is variable m the lateral spines of the rostrum, having 

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

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

 specimens from South Africa, one has three i^airs, two have two 

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

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

 one young example the rostrum is armed with two spines on one 

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

 other dififerences. 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 

 chcliped 56 mm- long, but that on the right only 23 mm., its kst 

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

 ill contrast v;ith the adjoining orange red, stmngly setose thiid 

 maxillipeds, which have the inner margin of the third joint 

 toothed or nodulose.
