 albo-c£Erulescentibus. 



Habitat, Spanish Maine. 



Remarks.— Mv. G. B. Sowerby, in the 1st part of his Malacologicaland Con- 

 chological Magazine says, that this shell is only a variety of Ampullaria fasciatai 

 Lamarck. I received eight specimens of this beautiful shell, all precisely alike, 

 except that some were larger than others. The person from whom I obtained 

 them told me that they came from the Spanish Maine; and I am still of the 

 opinion that it is a distinct species.

H. tesia Eubglobo.sa, imperforala, spadicea; anfractibus fasciis albis Iransversis. 

 Habitat, unknown. 



Remarks. — I have received another specimen of this pretty Helix, which was 

 brought by a sailor from the Isle of France.
