LAND SHELLS 

 OF ILFRACOMBE AND NEIGHBOURHOOD. 



By J. R. B. TOMLIN. 



The following list is the result of intermittent collecting from 

 March 17th to 31st, by Mrs. McKenny Hughes, Miss Alford, 

 and myself, during a geological expedition. The ground ex- 

 plored may be included in a radius of about eight miles from 

 Ilfracombe. Geologically this area belongs to the Middle 

 Devonian group, passing into the Upper Devonian near 

 Braunton, which was the southern limit of our investigations. 

 On the east we did not get beyond the ' great Hangman.' 

 Most noticeable is the hillside at Hele (two miles to the east of 

 Ilfracombe), where white vars. of Arion hortensis, Hyalina 

 cellaria, and Helix rotundaia all occurred. 

 Limnaea peregra (Miill.). At Lee only. 

 Ancylus fluviatilis Miill. In all fast streams. 

 Arion ater (L.). Not common; the black and brown forms 



noticed. 

 A. hortensis Fer. Abundant everywhere; two albinos at Hele. 

 Amalia marginata (Miill.). Common on east side of Hele 



Bay. 

 Limax nnaximus L. Very seldom seen ; at Combe Martin 



and Challacombe. 

 L. agrestis L. Ubiquitous. 



Testacella haliotidea Drap. At Hele Bay — four live speci- 

 mens and one shell — under stones deeply buried in the 

 ground. The animals were small and light-coloured. 

 Vitrina pellucida Miill. Dead shells everywhere ; alive at 



Watermouth, Hele, Combe Martin, Widmouth, etc. 

 Hyalina cellaria (Miill.). Common everywhere — finest at 



Hele. 

 H. cellaria var. albinos Moq. Some lovely specimens with 

 the Testacellce.
