S. C. COCKERELL : SHELLS IN NORMANDY. 15 



Z. crystallinus (Miill.) — Veules. 



Helix pomatia L.^ — Dieppe. 



H. aspersa Miill. — Everywhere. The most common form at 

 Veules was the dark one with no distinct hands. I also 

 noticed there one specimen each of the vars. grisea Moq. 

 and conoidea Picard. 



H. nemoralis L. — Dieppe, Puys, Veules, and Rouen. I have 

 only one specimen from Dieppe, which is var. rubella 10345. 

 From Veules I have several including rubella 00300, 12345, 

 and Ubellula 00000, 12345, 12045. -^^ Rouen I took var. 

 castafiea 00300, var. rubella 00000, 00045, ^"""d var. Ubellula 

 00000, 00300, 00045, 00345, 02335, 12345, 123(45). 

 The most abundant form was that with the two first bands 

 missing. Curiously enough I found this form predominant 

 at Brussels in 1883 — it appears to be rather local in Eng- 

 land. 



H. hortensisvar. lutea Moq. 00000, Dieppe. Veules yielded 

 several interesting varieties including lutea 00000, 00300, 

 00305, 10305, 1(234)5, 10305, arenicola, and incarnata 

 00000 fuscolabiata. 



H. cartusiana Miill. — Rouen, Puys, and Dieppe, some being 

 as large as small H. cantiana. 



H. concinna Jeff. — Rouen. 



H. hispida L. — Puys and Veules. 



H. virgata Da Costa and var. albicans Grat. Puys and 

 Veules. 



H, caperata Mont.— Puys. 



H. ericetorum Miill. — Rouen. 



H. rot un data Miill. — Rouen and Veules. 



H. pulcheila Miill.— Veules. 



H. pulcheila var. costata Miill. — Rouen. 



H. limbata Drap. — Rouen ; with vars. albina and minor. 

 The animal appears to be light and dark according to the 

 colour of the shell. 



Bulinnus obscurus (Miill). — Veules and Rouen.
