DEFINITIONS

FRINGILLA
(Fringillidae; Ϯ Common Chaffinch F. coelebs) L. fringilla (also frigilia, fringuilla, fringillus, fringuillus, frenguillus, fringuellus, fringuillo)  finch, subsequently associated with the Chaffinch; "98. FRINGILLA.  Rostrum conicum, rectum, acutum." (Linnaeus 1758); "Fringilla Linnaeus, 1758, Syst. Nat., ed. 10, 1, p. 179. Type, by tautonymy, "Fringilla" = Fringilla coelebs Linnaeus." (Mayr in Peters, 1968, XIV, p. 203). Linnaeus's Fringilla comprised thirty-one  species (F. oryzivora, F. cœlebs, F. Montifringilla, F. lulensis, F. lapponica, F. sylvatica, F. melancholica, F. erythrophthalma, F. Carduelis, F. Melba, F. Amandava, F. Gyrola, F. rubra, F. tristis, F. Zena, F. brasiliana, F. butyracea, F. Canaria, F. Spinus, F. flammea, F. flavirostris, F. cannabina, F. Linaria, F. angolensis, F. violacea, F. Schœniclus, F. domestica, F. montana, F. chinensis, F. hyemalis, F. Zena). Modern research suggests that some of the southern and insular subspecies of the Common Chaffinch may be entitled to specific rank, e.g. canariensis, spodiogenys, moreletti.
Var. Frangilla, Fringuilla, Fringille, Frlngilla.
