as "I'ort commune dans toute la Suisse occidentale." I found it at 

 Belmont, les Rocliers Nayo, Lausanne, Dcvens, Blonay, and Mont- 

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

 rinea amphibia. Helix arljK.sfoni/ti and nemoralis, Pvpa arena, Clau-

C. plica tula is undoubtedly distinct from ('. Rolphii ; but whether 

 C. Mortilleti is not a variety of C liolp/iii is another (juestiou. 

 Judging from a comparison of specimens of C. MortilU'd kindly sent 

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

 figured bv the authors of the ' British Mollusca,' I am inclined to 

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

 The differences pointed out by Mr. Benson are e(|ually observable in 

 varieties of C. niijricans an«l C. bidens. However, Air. 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. Gvvyn Jeffreys.
