24 Mr. J. G. Jeffreys's Notes on Siviss Mollusca. 



Helix rufescens, Montagu (var.). 

 Helix circinata and 7nontana, Stud. 

 Var. Albida. 

 Mont Tendre. 



Helix (Trichia) clandestina, Hartmaun. 

 Zurich; Lucerne; Scliwyz (Charp.). 



Helix strigella, Drap. 



Foully; Sion; Tourbillon, and other parts of the Valals(Charp.); — 

 Clermont, and on the side of the Geneva road near Lausanne ; 

 St. Nicholas ; Chable. 



Helix fruticum, Drap. 

 Saleve, near Geneva. 



Helix Carthusianella, Drap. 



Near Aigle (Charp.), and found by myself at Devens. 



Helix incarnata, Drap. 



Belmont and Sauvebelin Woods, near Lausanne ; Dent de Jaman ; 

 Pr6 de Joux ; Vufflens. Common. 



Helix candidula, Stud. 

 Le Saleve, near Geneva. 

 The Helix Cenisia of Charpentier is the H. apicina of Lamarck. 



Helix rotundata, Miill. 

 Var. Albida. 

 Belmont and Beme road, near Lausanne. 



Helix ruderata, Stud. 



Vallee d'Ormonts (Charp.); — Valley of St. Nicholas and Zermatt, 

 where I also found a greenish-white variety. Not uncommon. 



Helix 7-upestris, Drap. 



Var. (?) H. umbilicata, Mont. 



On rocks and under stones in many places, and at different heights 

 varying from 1200 to 5000 feet above the sea-level. Common. 



This species was accidentally omitted by ]\L Charpentier in 

 his Catalogue. I am not satisfied that the H. umbilicata of 

 Montagu is not specifically distinct. This and the typical form 

 are found together on the limestone rocks near St. Maurice.
