Our British Snails 43 



Animal usually nearly black. Very fond of 

 moisture. Anatomically related to A. lapicida, 

 but no external resemblance. 



Helix {Theba) cantiana. — First observed in Kent 

 (where it is especially fine and abundant),' whence 

 its specific name, but generally dispersed in 

 South and East England. A dull, creamy white 

 shell with a pink tinge, sometimes becoming 

 partially or wholly reddish. 



Helix {Theba) cartusiana (first noticed near 

 a Carthusian monastery). Much resembles 

 cantiana, but is much smaller and more smooth. 

 Chiefly found on the downs of Kent and Sussex. 

 Used to be common on Deal sand-hills — now 

 devastated by golf ! The tint in this is brown, 

 in the former red. 



H. (Hygromia) rufescens.- — A flatfish, dark 

 brown shell, abundant in the south of England, 

 and not rare elsewhere. Has a semi-lunar mouth 

 with a white internal rib. In gardens seems to 

 prefer violet beds. 



H. (Hygromia) hispida, i.e. hairy. — These hairs 

 are deciduous, and the hairless variety used to be 

 considered a separate species under the name of 

 concinna (^.^. neat), but would now be the variety 

 depilata, or bald. Broad and deep umbilicus. 

 Common, except in Ireland. Usually associates 

 with H. rufescens in moist places. 



H. [Hygromia) granulata is also hairy with white 

 silky bristles. Yellowish in colour. Shell thin.
