* Mr. Lea divides this species because one of his specimens is umbilicated, the 

 other not. I possess every variety between the two extremes from those with a 

 simple indentation, to others profoundly umbilicated 



Deshaycs, in his Tertiary tables, announces a new genus for this shell, but 

 givea it no name. It may perhaps be properly referred to Pyramis, Brown. The 

 specific name terebellata is preoccupied in the genus Pyramidella.
