 Common and sometimes in profusion, on grass and bushes 

 near the sea. It is most usually found on a sandy soil ; 

 and in situations characterized by plenty of sand, it 

 appears earlier in the year, in others scarcely before 

 July. Most of the banded Helicidas have similar habits.

 it in Cornwall ; as I suppose I have also done.

 noticed by Montagu, that its substance is so thin and 

 flexible as, when the animal dies, to contract with it into 

 depressions. I have found a few specimens which were 

 as thin and flexible as tissue paper.

 p. 410, p!. 18. Mr. Bellamy discovered this species near 

 Mevagissev, and it has been since found by Mr. Forbes in 

 Guernsey. Mr. Bellamy's original specimen was examined 

 by the eminent naturalists present at the meeting of the 

 British association at Plymouth in 1841 ; and especially 

 by Mr. Gray.
