' The reference to Sowerby by PfeifFer, -wlio at first (in 

 Kuster's Chemnitz) attributed the species to Sowerby, was f. 320, 

 321 ; the latter was omitted by our printer ; the former is, how- 

 ever, the less like our ideal. 



- The fine white basal groove which indents the inner lip is 

 a useful distinguishing characteristic. 



' Having washed the type, the band alluded to by Benson 

 proved to be mere dirt, and in place of paler flames near the apex 

 there were red wavy lines on a paler ground. 



* The C. Leai of Tryon (Amer. J. C. vol. 5, p. Ill, pi. 10, f. 

 6), who doubts its identity with the Chemnitzian species. 



' Reeve, who did not know this shell, quotes it as a synonym 

 of excellens {said to come from Birmah), the single type of which 

 is much nearer his labiosus. 



" Proc. Zool. Soc. 1852, p. 146: Kust. Chemn. Cyel. pi. 49, 

 f. 12, 13, as Cyclost. ; Mon. Pneum. vol. 1, p. 93. Ceylon. 

 Reeve's figure (C. Icon. Cyclop, f 83) looks very different from 

 Kuster's, yet both were from Cuming's types. 



' Found also in the jungle of Coorg. 



» An. Mat. 1863, ser. 2, vol. 12, p. 96.— Pf. Mon. Pneum. 

 Tol. 2, p. 66. Eeeve's figure is not our ideal. 



" This species is figured in Pfeiffer's "Novitates," pi. 98, 



f. 3, 4. 



This appears either a form of Theob:ildianus (?), or possibly 

 an unrecognised species. 



" Cyclostoma, f. 115, of Sowerby's Thesaurus (vol. 1) seems 

 identical. 



In Benson's manuscript I note that he regards this specicH 

 as identical with the torquatus of Hutton (J. Asi. Beng. vol. 

 3, p. 82) from Rajmahal. 



According to Sowerby, this is the Merguiensis of Pfeiftei- 

 (Pr. Z. 1857, p. Ill, and Mnn. Pneum. vol. 2, p. 216); if so, 

 that name would have priority, but he is wrong. 



'* To limit our work, we have excluded the estuary species 

 (of course the marine), and, perhaps, a few fluviatile ones, at 

 least such as are found far oiF from the sea. The omitted shells 

 are N. Peguensis, Bl. (? = Bengalensis, Potiez) ; N. rostrata, 

 Reeve ; N. crepidularia, Lam. ; N. violacea, Gmel. (depressa, 

 Bn.'i: N. cornucopia, Bn. (melanostoma, Tros. and Indiea Soul.); 

 with which estuary shells may be compared N. pileolus. Reel. ; 

 N. intermedia, Desh., and N. mitrula, Beck (in Gal. Douai) ; N. 

 Layardi, Reeve ; N. Colombaria, Reel. ; N. triserialis. Sow.; X. 

 Smithii, Gray (tigrina, Benson, hamuligera, Tros.); and X. 

 Coromandeliana of the Conchological Illustrations.
