DEFINITIONS

PLUVIANELLUS
(Chionidae; Ϯ Magellanic Plover P. socialis) French name "Pluvianelle sociable" given to the Magellanic Plover by Hombron & Jacquinot 1842  < dim. Pluvier  plover; "PLUVIANELLUS Homb. & Jacq.   Bill small, with the base rather depressed, and the apical half slightly vaulted, and arched to the tip, which is acute; the gonys half the length of the lower mandible, and ascending; the nostrils lateral, and placed in a membranous groove that extends for half the length of the bill, with the opening linear and longitudinal.  Wings very long and pointed, with the first quill the longest.  Tail moderate and slightly rounded.  Tarsi much shorter than the middle toe, and covered in front with transverse scales, and on the sides with reticulated scales.  Toes long, with the outer toe longer than the inner, both free at the base, and the sides of the fore toes slightly margined by a membrane; the hind toe rather short and elevated.   P. socialis (?) Homb. & Jacq.  Voy. au Pole Sud, Ois. t. 30. f. 1." (G. Gray 1846); "Nous pensons, avec MM. Hombron et Jacquinot, que ce genre appartient à la tribu des Charadriens. Il se rapproche du genre Squatarola par la présence d'un petit pouce et par ses tarses réticulés; il s'en éloigne par la disposition de ses narines, qui n'occupent que la moitié postérieure du bec, tandis que dans les Vanellus et Squatarola, les ouvertures nasales sont continuées par un sillon jusqu'à la réunion du tiers médian avec les tiers antérieur de la mandibule supérieure. Sous ce dernier point de vue, l'analogie est complète entre les genres Charadrius et Pluvianellus. De sortie que si, en nous basant sur l'absence ou la présence du pouce, nous établissons dans la tribu des Charadriens deux séries parallèles, le genre Pluvianellus représentera, dans la seconde série, le genre Pluvier qui se trouvera placé dans la première" (Jacquinot & Pucheran 1853); "Pluvianellus "Hombron and Jacquinot" G. R. Gray, Gen. Bds., 3, Dec., 1846, p. [549]. Type, by monotypy, P. socialis? Hombron and Jacquinot = Pluvianellus socialis G. R. Gray.¹  ...  ¹ Pluvianellus Hombron and Jacquinot was not published until 1853 (Voy. Pôle Sud., Zool., 3, Mamm. et Ois., p. 124). The species was figured in the "Atlas" (pl. 30, f. 1), which apparently appeared between 1842 and 1846, under the vernacular name of "Pluvianelle sociable."" (Peters 1934, II, 258). The Magellanic Plover has been treated in a monospecific family.

● "Spizella socialis (Wils.)  ...  Bartram calls it "Passer domesticus, the little House Sparrow or Chipping-bird." The bird was so common that Wilson, though its first biographer and namer, makes no mention of it as a novelty" (Trotter 1907) (syn. Spizella passerina).
