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

 Teba rufescens. Leach, Mollusc, p. 96. 

 Helix glabella. Drap. p. 102. t. 7.f. 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
