Curiously the Pliocene form of Florida is identical, not with the 

 existing type of the Antilles, but with that of the southeast Atlantic, 

 St. Helena, and the Cape Verde Islands, a variety with the angle of 

 the ribs minutely crenulate, which I have named Cardium spinosum 

 var. turioni. The Pacitic species is hardly more than varietally dif- 

 ferent from the West Indian form, and will retain Sowerby's name of 

 aspersum in a varietal sense.
