(w) A. Heteroclita is mentioned in the text. An ex- 

 amination of Mr. Laskey's figure in the Wernerian Trans- 

 actions has rendered us extremely doubtful as to what 

 genus it should he placed in. We have never seen the 

 shell which was introduced into the catalogue as an Auri- 

 cula on the authority of Mr. Fleming. The figure some- 

 what resembles a reversed Achatina Acicula.
