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 description and his figure. I lately received from my kind and learned friend, the Abbe Brugnone of Palermo, a fossil shell named E. tuberculosa, 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. papillosa 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. |
