408 On the Land Shells of Bourbon. [No. 4, 



prominent, pointed, orange-coloured hook close to it. Found with 

 Helix ccelatura, tolerably abundant, but local, at a considerable 

 elevation, in damp places. 



14. Nanina (Macrochlamys) nitella, Morlt., Eev. Zool. p. 

 219. 



This Mauritian species is recorded by Deshayes, Moll, de la 

 Eeun. p. 85, as also found in Bourbon, I did not find it, however, 

 at the latter Island. I have described the animal from Mauritian 

 specimens, Proc. Zool. Soc. 1868, p. 258. 



15. Nanina? proletaria, Morlt., Ser. Conch, p. 60. 

 Another Mauritian shell, mentioned by Deshayes as found 



with the preceding, I think it just possible, he may have mis-identi- 

 fied his Bourbon specimens, and that they may prove to belong to 

 the species subsequently described by H. Adams as iV. Geoffreyi f 

 I certainly found no shell of this type, with the last whorl angu- 

 lated, or carinated, at the periphery, agreeing with Morelet's 

 description of N. proletaria. 



16. Nanina pr^tttmida, Fer. Bull. un. des sc. p. 303. 

 Animal white, thickly sprinkled with dark grey, especially on the 



neck, tentacles iron-grey ; provided with a mucous pore. Yery local, 

 but not rare, found at a considerable elevation in damp woods J 

 amongst decaying vegetation &c ; living under the same bushes ; 

 distinguishable only by the proportions and number of the whorls 

 and by the total absence of the strong canaliculation of the sutures ; 

 I found a good many specimens of a shell which I will now de- 

 scribe. 



17. Nanina Cordemoyi, n. s. 



Shell almost exactly like the preceding, only a shade smaller ; * 

 with only five whorls, not compressed, with the suture not canali- 

 culated, somewhat indistinctly banded with a rather broad brown 

 belt ; slightly more openly perforated. 



N. prcetumida, height 6^, diam. 9 m. m. ; 



iV. Cordemoyi, ditto 6, ditto, 8£ m. m.
