The name is from the Latin patera ("a saucer"), and refers to the highly depressed, saucer-like shape of the shells of these snails. In addition to flattened shells, members of the group have an imperforate umbilicus and a single tooth on the parietal wall of the aperture.[2]

These snails are known only from the eastern United States.[3]
