LintKzan Society March 1. Read, a letter from James Lindsay, M.D. 



describing the Helix obvoluta, found in Hampshire. 



The author, last May, met with this along with the other Helices, such as 

 nitida and rufescens, amongst the moss and roots of trees in JDebham wood, 

 near Brinton, Hampshire, and along the north side of the South Downs. 

 There are smooth tooth-like processes on the inner side of the lip, of which 

 Lamarck takes no notice. The aperture is triangular, mouth a little 

 reflected, forming a distinct sinus externally, and altogether answering to the 

 Lamarckian description.
