Inhab. gardens and hedges. 



Animal black-grey ; upper tentacles thick. 



Shell growing to three quarters of an inch in 

 diameter, but often smaller, semitransparent, vary- 

 ing from pale ash-colour to rufous brown, Fig 38< 

 often marbled and mottled with paler or 

 darker blotches, rarely pure white, slightly 

 carinate in the middle of the larger volu- 

 tion by a paler band; aperture semielliptic, thin, 

 and slightly reflected, longer than broad. Both the 

 young and old shells are quite bald. (fig. 38.) 



Montagu, and all who have copied from him, 

 have represented the young of this species as clothed 

 with hairs. He probably mistook the Helix hispida 

 for it. 



Lister gives some details of the anatomy of this 

 species (Anat. t. 4. f. 4.). 



The shell varies greatly in colour, being generally 

 reddish brown, but passing from that colour to 

 nearly transparent or translucent white; and in 

 shape and size. Tab. 4. f. 36., which Dr. Turton, 

 in the first edition, gave for H. fusca, appears to 

 represent a small higher variety of this species, 

 which is often met with near Battersea.
