DEFINITIONS

AGELAIOIDES
(Icteridae; Ϯ Greyish Baywing A. badius) Genus Agelaius Vieillot, 1816, blackbird; Gr. -οιδης -oidēs  resembling; "III.—Genus DOLICHONYX, Swainson.   ...   2. Agelaioides.   2. DOLICHONYX BADIUS, (Vieillot.)  Agelaius badius, Vieill. Nouv. Dict. xxxiv. p. 535, (1819.)  Icterus fringillarius, Spix, Av. Bras. i. p. 68, (1824.)   ...   3. DOLICHONYX FUSCIPENNIS, nobis.  ...  This bird and the immediately preceding D. badius, present some structural characters, which entitle them to be arranged with nearly equal propriety in either Agelaius or in Dolichonyx, but I think not in Molothrus.*   /   *DOLICHONYX MELANCHOLICUS, (Linnæus.)  Oriolus melancholicus, Linn. Syst. Nat. i. p. 180, (1758.)  Edwards' Birds, pl. 85.  Judging from the figure and description of Edwards, I suspect that this is a third species of the same subgroup of Dolichonyx as D. badius and D. fuscipennis, (above described,) and at present unknown to naturalists."
