 county. I have seen some from Weymouth, and Mr. Petiver receivetf

Pennant has not noticed this Shell. Linnaeus described it as an 

 Asiatic species in the Systema Naturae, but adds it is perhaps an Eu- 

 ropean species also. In the last edition by Gmelin, it stands expressly

 glossy, with numerous concentric transverse wrinkles, and several 

 faint rays in a longitudinal direction. The margins are plain, The 

 inside milk white and glossy.
