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.
