Genus Patera Albers, 1850

Helix (Patera) Albers, 1850: 96. Type species: Helix appressa Say, 1821, by subsequent designation (Pilsbry 1930: 326) [non Patera Lesson, 1839 ( Cnidaria)].

Remarks.

Patera is a junior homonym of Patera Lesson, 1839 ( Cnidaria). However, Patera Lesson, 1839 has only been used in a few treatises during the 19th century and at the beginning of the 20th century, whereas Patera Albers, 1850 is in widespread use. As such, continued usage of the junior homonym is in the best interest of stability and the case should be referred to the International Commission on Zoological Nomenclature for a ruling under Art. 23.9.3 of the Code (ICZN 1999).
