 In 2002, researchers found that an older name "Helix depilata" Draparnaud, 1801 referred to the same species, but this name had never been used after 1899 and was fixed as a "nomen oblitum" under this rule by Falkner "et al".2002.Such a reversal of precedence is also possible if the senior synonym was established after 1900, but only if the International Commission on Zoological Nomenclature (ICZN) approves an application.
