12. Buffon’s variety of the “Jean-le-blanc”
12.1. Linnaeus (1758): not considered.
12.2. Brisson (1759a: 367-370, 1763a: 107): “ LANIER BLANC ”, “ LANARIUS ALBICANS ”, species 18 of genus VIII (“Épervier”, “ Accipiter ”), order III, section 1.
OBSERVATION. — No direct observation. Description borrowed from Aldrovandi.
REFERENCES. — Aldrovandi (1599: 380-382), “ Lanarius ”, direct observation and various sources; Schwenckfeld (1603: 304), “ Milvus albus ”, based on Turner and Aldrovandi; Jonston (1657: 12, pl. IX), “ Lanarius ”, based on Aldrovandi; Sibbald (1684: 15), “ Milvus albicans. An Lanius albicans ? ” (in a list of Scottish birds); Rzączyński (1745: 395), “ Milvus albus ”, based on Aldrovandi and Schwenckfeld.
MODERN IDENTIFICATION. — Doubtful species. Aldrovandi mentioned two “ Lanarii ” and considered them two varieties of the same species: the first one (total length: about 50 cm) was probably a harrier; the second one, bigger (total length: about 70 cm), is not identifiable with certainty (the grey, white, and brown color, as well as the longitudinal rusty spots of the belly and beneath the wings evoke a juvenile male harrier too; however, it is not in accordance with the size). Furthermore, these two birds may have been confused, in the other mentioned sources, with other unidentifiable birds of prey.
12.3. Linnaeus (1766): not considered.
12.4. Buffon in Buffon & Guéneau de Montbeillard (1771a: 134- 135), quarto edition; (1771b: 105), folio edition: Variety of the “Jean-le-blanc” (see above, 11.4).
OBSERVATION. — No direct observation. Short description borrowed from Brisson.
REFERENCES. — Aldrovandi (1599: 380-382); Schwenckfeld (1603: 304); Brisson (1759a: 367).
MODERN IDENTIFICATION. — See Brisson. The identification of the second “ Lanarius ” of Aldrovandi with Buffon’s “Jean-le-Blanc” (i.e., * Circaetus gallicus) is very improbable.
12.5. Gmelin (1788: 276): “ FALCO ALBICANS ” G42, S102, order “ Accipitres ”. Includes a variety β.
REFERENCES. — Brisson (1763a: 107); Aldrovandi (1599: 380- 383); Latham (1781: 87 no. 73), “White Lanner”; based on Brisson and Aldrovandi.
REMARK. — Gmelin distinguishes between the two “ Lanarii ” of Aldrovandi; he considers one of them the main species, and the other the variety β; he wonders whether the species itself, “ Falco albicans ”, may be a mere variety of “ Falco Lanarius ” (G42, S24), i.e., Buffon’s “Lanier” (among “falcons” and related species).
DISTRIBUTION. — Europe.
MODERN IDENTIFICATION. — See Brisson.
MODERN NOMENCLATURE. — Falco albicans J. F. Gmelin, 1788, is a nomen dubium.
