* 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. 
* Deshayes, in his Tertiary tables, announces a new gens for this shell, but 
gives itno name. It may perhaps be properly referred to Pyramis, Brown. The 
specific name terebellata is preoccupied in the genus Pyramidella.
