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 Abbé Brugnone of Palermo, a fossil shell named £. 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 FE. elongata by the shape and much finer sculpture.
