Uemarl-s. — This species, recorded by several authors from the Miocene and 

 Pliocene of central and southern Europe, is widely diffused in the existing 

 Mediterranean. Wood records the type-form from the English Crag, but it is a 

 rare shell in our deposits. Dr. S. P. Woodward gives it from the Icenian of 

 Bramerton on the authority of the late Mr. R. Fitch, but the specimen cannot now 

 be traced. The late Mr. Charlesworth considered its occurrence at that locality 

 more than doubtful.
