82 Mr. W. T. Blanford on Indian Species of Land-Shells 



horn-shaped lobe, of very variable length, and possessing a cer- 

 tain amount of contractility. Of this group, which is probably 

 allied to Slenopus* (if, indeed, that name ought not to be adopted 

 for it), some of the principal Indian types are N.vitrinoides, Desh., 

 N. infula, Bens., N. pylaica, Bens., and N. amimlla, Bens. In 

 the other group the foot is broader, flatter, and rounded poste- 

 riorly, as in most of the true Helices. The mucous pore, gene- 

 rally of larger comparative size than in the first specified section, 

 is situated in a groove in the centre of the upper surface of the 

 foot, close to the posterior extremity, with no lobe whatever 

 above or in front of it. Amongst the principal types are N. 

 Icevipes, Miill v N. bistrialis, Beck, N. Tranquebarica, Fabr., N. 

 indica, Pfr., and N. Thyrceus, Bens. 



Before any complete list of Indian Naninas can be made, 

 several additional observations are necessary. Amongst the 

 species of which notices are especially desirable are the follow- 

 ing:— 



Nanina? Basileus, Bens. Anamullay Hills, S. India. 

 N.? Cyclopias, Bens. Darjiling, in the Sikkim Himalaya. 

 N.? Oxytes, Bens. Cherra, in the Khasi Hills. 

 N.? Orobia, Bens. Darjiling. 

 N.? serrulaf, Bens. Khasi Hills. 

 N.? climacterica, Bens. Khasi Hills and Arakan. 

 N.? anceps, Gould. Tenasserim. 

 N.? infrendens, Gould. Molmain. 

 N.? Bombax, Bens. Molmain. 

 H.? radicicola, Bens. Landour and Darjiling. 

 H.? bifoveata, Bens. Tenasserim. 

 H.? monticola, Hutt. Western Himalaya. 



The three species of SophinaX described by Mr. Benson, from Mol- 

 main, besides several of the species from Ceylon. 



In the following list, all species of which I have neither seen 

 the animals myself, nor authentic drawings of them, are marked 

 by italics, as are also all localities not verified by myself, 

 by my brother, Mr. H. F. Blanford, or by Mr. W. Theobald, 



* The name Nanina has been so generally employed by conehologists 

 for the great genus of shell-bearing Helicidse characterized by the presence 

 of a mucous pore, that, although objectionable both on account of its 

 signification and of other terms having unquestionable priority, no good 

 purpose could now be served by attempting to change it. 



t H. Bensoni, v. d. Busch, is the same shell as JV.? serrula, Bens., if the 

 specimen of the first-named in Mr. Cuming's cabinet is authentic, which I 

 believe it is. 



X I am inclined to anticipate that these may very possibly prove to be 

 Naninas.
