23 Mr. J. G. Jeffreys's Notes on Swiss Molliisca. 



This species has also been lately taken by Mr. Mac Andrew at 

 Burgos in Spain, at an elevation of between 2000 and 3000 feet 

 above the level of the sea. 



Vitrina elongata, Drap. 



Valley of St. Nicholas, at an elevation of about 4000 feet. Eare. 



This species had not been found before in Switzerland, and 

 was supposed to be confined to the champaign parts of France 

 and Germany. 



Succinea Pfeiffen, Rossmassler. 



Clarens ; Martigny (Chai-p.) ; — Lac de Bret ; Belmont, and other 

 places near Lausanne ; Villeneuve ; Vallee de Bagnes ; Visp ; 

 Lacs de Joux et Brenet. Rather common. 



At first considered by Charpentier to be a variety of Succinea 

 putris. 



Succinea oblonga, Drap. 



Valley of the Rhone (Charp.). With the last: not uucommon. 



A variety of a larger size and greenish colour occurred to me 

 in Belmont Wood, near Lausanne. 



Helix Pomatia, Linnaeus. 



I found a depauperated variety, of the usual size, on the Dent 

 de Jaman, at the height of about 5000 feet. 



Helix aspersa, Miill. 



It is remarkable that our common garden snail, which is so 

 ^Nadely dispersed, from the Shetland Isles to Algiers, is not indi- 

 genous to Switzerland or any part of Germany. It is said that 

 the extreme severity of the cold in winter prevents its inhabiting 

 the latter countries. 



Helix sylvatica, Drap. 



This local species did not occur to me in the Jura, or west- 

 ward of Vevay, although it is common in the Alps, and plains 

 to the east. 



Helix zonata, Studer. 



Valleys of Entremont, St. Nicholas, and St. Bernard ; Simplon ; 

 Tessin ; Airolo (Charp.). I also found it at Zermatt, Randa, 

 and St. Nicholas, in the last-named valley. 



Helix personata, Drap. 



Bex ; Kandersteig, and Valley of the Lac de Joux (Charp.) ; — 

 Chaillv, and Belmont, near Lausanne ; Mont Tendre ; Rochers 

 Naye ; Chable ; also at Meillierie in Savoy. Not uncommon.
