above, mottled with nearly black irregular spots, which 

 become fainter on the paler sides, where they fall into 

 rows. The sole of the foot is pale grey. The upper ten- 

 tacles are somewhat clavate, the lower ones short. Pro- 

 fessor Macgillivray remarks that when crawling, it carries 

 its shell at an angle of about 50°, and directed backwards 

 a little to the right; when at rest the shell is directed to 

 an angle of 45°. M. Bouchard- Chantereaux remarks that 

 the young of this species do not arrive at their last stage of 

 growth before the first month of their second year. 



This Bulimus is found under stones, on old walls and 

 ruins, and on trees in woods. It is widely distributed 

 through the British Isles, extending to the north of Scot- 

 land. In many districts, however, it is local, and is not 

 unfrequeiitly found chiefly in those parts where there is a 

 limestone soil. 



Note. — It is just possible that the obscure and undetermined Helix stagnorum of 

 Pulteney (Hutchins, Dorset, p. 49) may be intended for this species; we know 

 not where else to notice it. It is thus described : — " Ovate-oblong, whitish, 

 sometimes brown; about three lines long; subturreted. Volutions six, minutely 

 striated, or rather wrinkled obliquely, in the transverse direction. Aperture 

 ovate, bordered with a white edge. Inhabits plants in moist places by rivers and 

 brooks, and in woods in Dorset."
