122 HELICID^. 



white with a faint yellowish tinge, the body whorl is usually more 

 or less tinted with rufous or fawn-colour, and generally encircled 

 by a faint white line placed a little above the periphery ; with 

 close-set, irregular, curved striae in the line of growth ; epidermis 

 thin and somewhat wrinkled ; whorls 6-7, convex, body whorl 

 occupying rather more than half of the shell, much rounded, 

 not keeled ; spire short, apex obtuse ; suture deepish ; mouth 

 oblique, forming about three fourths of an oval, with an internal 

 white or sometimes pinkish rib placed a little away from the 

 margin ; outer lip thin, slightly reflected, folding over where it 

 joins the pillar ; umbilicus narrow, but deep. 



Inhabits grassy banks in hedgerows and copses, 

 chiefly in the home and southern counties of Eng- 

 land. It also occurs in Yorkshire and Northumber- 

 land, as well as in some parts of Wales ; but it has 

 not been observed in Scotland, and it is doubtful 

 Avhether it has been found in Ireland. 



It is sluggish and irritable, and secretes an abund- 

 ance of transparent slime. The shell is inclined to 

 one side when the animal is crawling. It lays from 

 sixty to ninety globular eggs, which are deposited in 

 moist places. 



" It hibernates from November to February, and 

 forms an epiphragm like a film of the finest blown 

 glass," B.C.^ vol. i. p. 191. In the earlier stages of 

 its growth the epidermis is clothed with short bristles, 

 which are deciduous.

Body slender, moderately transparent, yellowish, faintly tinged, 

 especially in front, with pale rose-colour, tubercles thickly set 

 and finely dotted with brown ; tentacles long, yellowish, trans- 



* So named because it was first discovered near a Carthusian 

 monastery.
