124 HELICID^, 



thick, scarcely semitransparent, of a dullish aspect, varying in 

 colour from ash-grey to rufous-brown, sometimes streaked with 

 darker or paler markings, and usually having a white band 

 round the centre of the body whorl ; with close-set, irregular 

 striae in the line of growth ; periphery bluntly keeled ; epidermis 

 moderately thick ; whorls 6-7, body whorl occupying about half 

 of the shell ; spire short, apex obtuse ; suture deepish ; mouth 

 oblique, semilunar, with a strong white internal rib which is 

 situated a little away from the margin ; outer lip thickish, some- 

 what reflected ; umbilicus rather narrow, but deep. 



Inhabits most parts of Great Britain, in woods, 

 gardens, and hedgerows, on grass at the foot of walls, 

 among nettles, and under logs of wood and stones. 

 It is one of the most abundant of our land shells ; its 

 colour is very variable. The epidermis of young 

 specimens is clothed with short hairs, which are shed 

 as the animals advance towards maturity. The eggs 

 of this species vary in number from forty to fifty and 

 are laid during the months of August, September, 

 and October ; the young are hatched in from twenty 

 to twenty-five days. 



Var. I. albida. — '&\v€(\. white or colourless. Not uncommon. 

 Var. 2. minor. — Shell smaller, spire more raised. Not un- 

 common. 



Monstrosities sometimes occur.
