examples have the epidermis covered with short hairs 

 which soon fall or get rubbed off. 



The Carthusian Snail {H. carthusiana) claims close 

 kinship with the Kentish Snail, but it is smaller, more 

 depressed above, more convex beneath, more solid in 

 structure, less transparent. The colour is 

 yellowish white, tinged with fawn colour, 

 usually Avitli a white spiral band on the 

 body-whorl as in the Kentish Snail. The 

 mouth is strengthened by a white rib, but 

 it is placed nearer the opening than in the las. 

 species. Umbilicus narrow, and partly concealed by 

 the growth of the lip. It occurs only in hollows of 

 the South Downs in Kent and Sussex. 



The Copse Snail (H. arhustorum) has a solid and 

 very globular shell three-quarters of an inch across. 

 Its colour is a pinkish brown splashed and spotted with 

 yellow, and with a darker brown spiral line running 

 just above the middle of the whorls. In many 

 specimens the thin epidermis has largely perished. 

 The mouth is strengthened by a broad white rib at 

 the lip. The small umbilicus is almost hidden by 

 the outer lip. Although its range extends through- 

 out Great Britain, it is distinctly local in its occur- 

 rence, and does not appear to inhabit Ireland. Moist 

 and shady woods, especially of alder and willow, and 

 the neighbourhood of streams, are its favourite resorts. 

 It is possible that this species finds abundant moisture 

 a necessity, for Mr. T. Scott has recorded that a 

 specimen kept in a kitchen knew the way to the 

 cold-water tap which it was in the habit of visiting, 

 and apparently enjoyed the water which fell upon it.
