Note. — Punctata, stercus-muscarum, trizonata. The two 

 first are pyriform aud closely allied. The dots in stei-cus- 

 muscarum are uniformly finer, and the teeth smaller and 

 more numerous than in punctata. The third species is 

 named from a specimen in the collection of Miss Saul, who 

 also has a young shell, probably of the same species, here 

 named trizonata. It is more cylindrical and solid than 

 stercus-muscarum, which it resembles in the smallness of the 

 teeth.
