(syn. Charadrius Ϯ Greater Sand Plover C. leschenaultii) "LE PETIT PLUVIER A COLLIER  ... Les Grecs l'appellent Xαραδριος. Aldrov.  ...  Les Lapons, PAGO. Linn." (Brisson 1760); "The species C. geoffroyi requires consideration: continually confused with C. mongolus on account of its similar coloration, the two were considered varieties of the same species by Gould and described as Hiaticula inornata.  A later writer found them difficult to separate, whereas by Baird, Brewer, and Ridgway they were placed in different genera. I am also adopting that course, and as no generic name has yet been provided for C. geoffroyi, I introduce PAGOA, gen. nov., with C. geoffroyi Wagler as type." (Mathews 1913); "Pagoa Mathews, Bds. Austr., 3, 1913, p. 82, 98. Type, by original designation, Charadrius geoffroyi Wagler = Charadrius leschenaultii Lesson." (Peters 1934, II, 246).
