Land-snails 355 



aloiif^ lioclgerows, in gardens and woods. It is partial 

 to beds of strawberry and violet, and in tlie former 

 may do great damage to fruit without its presence 

 being suspected, the destruction being debited to 

 birds. If a visit be paid to the strawberry bed 

 after a heavy summer shower, a different tale may 

 be told. Thrushes appear to be very fond of this 

 species as a food. In its young state — that is up to 

 the ao-e of four whorls — the shell is covered with 

 hairs, but these are short and readily fall oft'. 



The Silky Snail {H. granulata) may be mistaken 

 for the Bristly Snail, but though the diameter of the 

 shell is about the same in each, that of the Silky 

 Snail is thinner, and more globular, being more 

 rounded both above and below. The colour too is 

 greyish white, with some approach to glossiness. The 

 thick epidermis is covered with long fine downy 

 hairs which do not fall off. The spire is considerably 

 raised, the umbilicus exceedingly narrow and almost 

 closed. The feel of the shell when handled is quite 

 distinct, and so numerous are the hairs that it may 

 be dropped on hard surfaces with impunity. It is a 

 local species, found on mossy hedgebanks. In Corn- 

 wall I found it had a great weakness for the Hart's- 

 tongue fern {Scolopcndriii'iii vulgare). The Green 

 Hairy Snail (H. revelata) is of similar proportions 

 to the Silky Snail, but is compressed above. The 

 shell is very thin and semi - transparent (which 

 granulata is not), coloured yellowish green, and the 

 four and a half whorls are wrinkled transversely, 

 which gives the very deep suture the appearance of 

 being puckered. The thick epidermis is covered with 

 short white hairs which are easily detached. The
