single specimen of which Nevill had never seen, so that there is 

 very considerable doubt whether his determination is correct. 

 Turning next to No. 133, p. 34, Nanina (Sitalat) subdecussata, 

 Pfeiffer, it is clear that Nevill considered this species distinct from 

 No. 134, and he gives as the locality Madras (10) and Pooree 

 (Raban, 2) var. (? distinct species) Trichinopoly (1), Stoliczka : 

 these had apparently not been compared and verified with the 

 species from the typical locality Bombay, on the opposite coast of 

 India : so far, this identification is unsatisfactory. No. 128, Nanina 

 (Sitala ?) layardi, Pfr., p. 34 : Nevill's record is all from Ceylon, 

 includes shells given by Layard himself, and Nevill clearly distin- 

 guished them from No. 133 and No. 134.]
