Helix rufescens. Montagu, p. 420. t. 23./. 2. 

 Teba rufescens. Leach, Mollusc, p. 96. 

 Helix glabella. Drap. p. 102. t. 7./. 6. 



Shell growing to three quarters of an inch in dia- 

 meter, but is often smaller, semitransparent, vary- 

 ing from pale ash-colour to rufous brown, often 

 marbled and mottled with paler or darker blotches, 

 rarely pure white, slightly carinate in the middle 

 of the larger volution by a paler band : aperture 

 semielliptic, thin and slightly reflected, longer than 

 broad. 



Montagu, and all who have copied from him, have 

 represented the young of this species as clothed 

 with hairs ; but we have a complete series, all 

 preserving their exact characteristics, and without 

 the least appearance of hairs. We believe that 

 what he mistook for the young, is our Helix his- 

 pida, No. 41. 



29. Helix sericea. Shell somewhat globular, trans- 

 parent, yellowish horn-colour, hairy, with nearly
