as "fort commune dans toute la Suisse oceidentale." I found it at 

 Belmont, les Rochers Nave, Lausanne, Devens, Blonay, and Mont- 

 reux. For the same reason 1 omitted such common species as Sue- 

 cinea amphibia. Helix arbustorum and nemoralis, Pupa aveiia, ClaU' 

 silia par villa y Cyclostoma eleganSy and Ancylus Jluviatilis. 



C. plicatula is undoubtedly distinct from C. Rolphii ; hut whether 

 C. Mortilleti is not a variety of C. Rolphii is another question. 

 Judging from a comparison of specimens of C. Mortilleti kindly sent 

 me by Mr. Prentice, with specimens of C. Rolphii, described and 

 figured by the authors of the ' British Moliusca,' I am inclined to 

 think they ought to be united. Mr. Hanley is of the same opinion. 

 The diiferences pointed out by Mr. Benson are equally observable in 

 varieties of C. nigricans and C bidens. However, Mr. Benson has had 

 great experience in the discrimination of species from varieties ; and 

 (as I remarked on a former occasion) naturalists may fairly differ on 

 this point. — J. Gwyn Jeffreys.
