Brocchi compares his species to C. ventricosa, and Lamarck to 

 C. adusta; but from comparison I consider it most nearly aUied to 

 C. cinerea and C. carneola. It differs from them in colour, which in one 

 of the specimens in my cabinet nearly resembles that of a recent shell; 

 in the columella being deeper and not so concave in front; and also in 

 general form, the shell being more pointed in front.
