Patera is a genus of land snails in the family Polygyridae.

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]

Henry Augustus Pilsbry was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a century. For much of his career, his authority with respect to the classification of certain substantial groups of organisms was unchallenged: barnacles, chitons, North American terrestrial mollusks, and others.
