Cassidula

Cassidula is a genus of small air-breathing salt marsh snails, pulmonate gastropod mollusks in the family Ellobiidae. Cassidula aurisfelis is known as Angulated Shoulder Earsnail, Angulate Vassidula or cat's Ear Cassidula inEnglish (Smith, 1992). It belongs to the great division orphylum called the Mollusca and from class of gastropoda.
