Nomenclatural notes on the East Asian form of the Mew Gull Larus canus Linnaeus, 1758 (Aves: Laridae) Author Mlíkovský, Ji Ř Í text Zootaxa 2012 3356 65 68 journal article 10.5281/zenodo.210789 d57af01f-0619-4880-ada2-2a1b3d8f440c 1175-5326 210789 " Gavina kamtschatschensis Bonaparte, 1857 " Bonaparte (1857: 224) listed " Gavina hinc Larus kamtschatschensis Bp. " in the synonymy of Larus niveus Pallas. The name is thus not available for nomenclatural purposes (Art. 11.6 of the Code) and the provisions of Art. 11.6.1 of the Code do not apply, because the name was already published in earlier works ( Bonaparte 1855 : 16, 1856: 771). In spite of this, Bonaparte's (1857) kamtschatschensis was used as a valid name for the taxon in recent literature (see above for citations), probably following Peters (1934: 315, footnote) who argued that “a quotation [of a name in the synonymy of an available name] ipso facto renders the name a substitute name for the species in whose synonymy it is quoted. His argument does not match provisions of the Code (ICZN 1999).
