Distribution. None recorded in a recent or living state. 



Fossil. Miocene ? : Sicily (Seguenza). Pliocene : Sicily. 



This appears to be Libassi's species, and agrees with his short de- 

 scription and his figure. I lately received from my kind and learned 

 friend, the Abbe Bruguone of Palermo, a fossil shell named E. tu- 

 berculosa, which had the same shape as the recent shell, and in 

 which the sculpture on the upper part was likewise wavy, although 

 the cancellation was rather more nodulous in consequence of the 

 specimen not being in good preservation. It differs from E. papil- 

 losa in being more compressed at the sides, and is shorter or has a 

 rounded and more globular outline ; it is readily distinguishable 

 from E. elongata by the shape and much finer sculpture.
