DEFINITIONS

ORTHOGONYS
(Mitrospingidae; Ϯ Olive-green Tanager O. chloricterus) Gr. ορθος orthos  straight; Mod. L. gonys  lower mandible, gonys  < Gr. γωνια gōnia  angle; "ORTHOGONYS, Strickl.  (ορθος, rectus, γωνυς, gonys.)   Rostrum elongatum, compressiusculum, culmine obtuse carinato, a basi ad apicem curvato, commissura satis decurvata, tomiis paulo inflexis, maxilla vix emarginata, gonyde rectissima, nec ascendente. Nares ovatæ subbasales, pilis raris frontalibus tectæ. Alæ mediocres, remigibus 2, 3, 4, subæqualibus, 1^a paulo breviore. Cauda mediocris, rotundata. Tarsi subbreves, acrotarsiis scutellatis, paratarsiis integris; digiti mediocres, externus internum paulo superans, ungues satis curvati, acuti.   The general habit of this bird suggests the idea of a Tanagrine form, but it is distinguished from all the genera which I know by its elongate beak, much curved culmen, and perfectly straight gonys. The beak is somewhat like that of Lamprotes, but is not so high and compressed.   ORTHOGONYS VIRIDIS (Spix). Tanagra viridis, Spix, Av. Braz., pl. 48. f. 2."
