Shell about a fourth part smaller than H. nemoralis,

 is distinguished by its smaller size, in not being quite 

 so convex, in being more polished and thinner, and 

 in the white margin round the aperture.

 (Ferus. t. 36. f. 10.) 2. And in the whole of the 

 spires being more or less separated from each other.
