In the past, interested and dedicated BirdForum members greatly assisted in finding obscure references and original descriptions/diagnoses (ODs) to add to The Key, making it the go-to site for the etymology of scientific names in ornithology. I was recently surprised to find a few definitions/entries still revealing, “OD not yet seen,” and would appreciate any input regarding the ODs of the following;
cenchroides ● OD not yet seen (Severtzov, 1873, Vertikal. Ghoriz. raspred. Turkestan. Zhivot., pp. 63, 113) (syn. Accipiter badius). = CHECK!
chesnea OD not yet seen (Fuligula chesnea Hodgson, 1844, Gray’s Zool. Miscellany, p. 86, no. 458 (per Salvadori 1895)); perhaps a Nepalese name for the Eurasian Wigeon (?syn. Mareca penelope). = CHECK! (i.e. cheonea)
decipiens ● OD not yet seen (Salvadori, 1871, Atti Reale Accademia Scienze Torino, VI, p. 131) (subsp. Leptotila verreauxi). = CHECK!
Gelastes ● (Corvidae; syn. Pica † Eurasian Magpie P. pica) Gr. γελαστης gelastēs laugher < γελαω gelaō to laugh; OD not yet seen; “Gelastes Mäklin, Vetensk. Grund. für Bestamm. af Fogelert. Od Ordnungsf., pp. 106, 107, 1868; new name for Pica Brisson.” (Stuart Baker, 1930, Fauna British India, 2nd ed., Birds, VII, p. 4). = CHECK!
intermedia ● OD not yet seen (G. von Burg, 1921, Herkunft der Vögel und Säugethiere der Alpen, Der Weidmann, 3, no. 46, p. 8) (syn. Periparus ater).
Pyrgitopsis ● (Passeridae; syn. Passer † Southern Grey-headed Sparrow P. diffusus) OD not yet seen. “Pyrgitopsis A. Roberts, 1940, Birds of South Africa, p. 335 (not of Bonaparte, 1853). Type, by monotypy, Pyrgita diffusa A. Smith, 1836.” (JAJ 2023 per Richmond Index card). = CHECK!
Tchangtangia (Pteroclidae; syn. Syrrhaptes † Tibetan Sandgrouse S. tibetanus) Changtang, the wild, sparsely populated high plateau region covering much of northern Tibet; OD not yet seen (Kozlova, 1947, Referaty Nauchno-Issledovatel'skikh Rabot, Otdel. Biologiya Nauk (1945), p. 183); "Tchangtangia Kozlova, 1947 ... new name for Przewalskia Kozlova, preoccupied by Przewalskium Flerov, 1930." (Vaurie 1965).
