 others very fmall, and the apex very fine. 



This fpecies has fo much the habit of Helix auricula- 

 ria, that it is not an eafy matter to fcparate it from the 

 young of that fliell. We have, however, followed the 

 very refpeftable authors above quoted, in giving it a dif- 

 tinft place, though not without fome doubts. It rarely 

 exceeds five-eighths of an inch in length, and three- 

 eighths broad.

 junction of the fecond fpire than in' the auricularia ; in 

 being thinner and more tranfparent, and the mouth not

 fcription and figure given by Chemnitz, which Gmelin 

 quotes for the Linnccan limofa.
