in considerable numbers. In Cuba it is abundant, and 

 was probably transported thence to Florida. 



Remarks. This is an anomalous form, with scarcely 

 truncation enough at base to entitle it to a place in the 

 genus Achatina. Moreover, the fine, longitudinal bar- 

 ring, like Clausilia, is a character quite foreign to that 

 genus. It agrees somewhat better with Bulimus and 

 Pupa, with one of which we should be disposed to place 

 it. Without some definite place to arrange it else- 

 where however, we deem it inexpedient to remove it 

 from the genus where it was placed by the describer. 

 It is closely allied to Achatina Qossei, but is not half its 

 size. — [g.]
