The purpose of this application, under Article 23.9.5 of the Code, is to conserve the specific name of Helix spirorbis Deshayes, 1859 (currently Scolodonta spirorbis), a junior primary homonym of Helix spirorbis Linnaeus, 1758 (currently Anisus spirorbis). These names are currently in use, respectively, for species in two different families of terrestrial (Scolodontidae) and freshwater (Planorbidae) gastropods, that belong to different superorders. Both names have been treated as valid since they were proposed and both were transferred out of the genus Helix Linnaeus, 1758 before 1899. In fact, H. spirorbis Linnaeus had been reassigned even before Deshayes described his species. It is proposed that Helix spirorbis Deshayes, 1859 be conserved by ruling it is not invalid by reason of being a junior homonym of Helix spirorbis Linnaeus, 1758.
