Pio'ure 8. Ampullaria ochracea, Nobis. , ■ 



A. testa veDtrico50-globosa,tenui, leevi, ochracea; arifractibus convexis et ad suturas 

 albo-caerulescentibus. 



Habitat, Spanish Maine. 



Remarks. — Mr. G. B. Sowerby, in the 1st part of his Malacological and Con- 

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

 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 tiie 

 opinion that it is a distinct species.

H. testa eubglobosa, imperforata, spadicea; anfractibus fasciis albis transversis. 

 Habitat, unknown. 



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

 brought by a sailor from the Isle of France.
