The operculum always closes the ovh'ell. Among the specimens found in 

 America, we have discovered a variation a little more elongated, which we have 

 figured. 



It is remarkable that this species which existed on both shores of the Atlantic 

 at the end of the Eocene epoch no longer exists in America, even in the Gulf of 

 Mexico. 



Occurrence. Lower .Tacksonian: Jackson. Mississippi (rare). 



Middle Jacksonian: 34 miles south of Perry, Georgia (very rare). 



Vicksburgian : West bank of Conecuh River, Eseambia County, Alabama 

 (very rare) ; 1 mile north of Monroeville, Alabama (rare). 



Geological distribution Helvetian of Italy (Seguenza, Xeviani) of Touraine 

 (Cunu) ; Zanclean of Italy (Seguenza); Plaisancian of Italy (Manzoni) ; Sicilian 

 of Italy (Xeviani). 



Habitat. Atlantic in British waters. Ci.")-179 meters; in the British Channel; 

 in the Gulf of Gascony, 16G-250 meters; at the Azores, 120-130 meters; south of
