A native of North America ; introduce!, into our Fauna by 

 Turton, from having been found at Scarborough attached to the 

 bottom of an American vessel. It is precisely the plana of Say, 

 from which the unguiformis of the Mediterranean does not seem 

 essentially distinct : the latter is the Patella crepidula of the Lin- 

 ncean cabinet.
