DEFINITIONS

Chlorothraupis
(Thraupidae; syn. Habia † Carmiol's Tanager H. carmioli) Gr. χλωρος khlōros  green; θραυπις thraupis  unknown small bird, perhaps some sort of finch.  In ornithology thraupis signifies tanager; "CHLOROTHRAUPIS.  Chlorothraupis, Ridgway, Pr. U. S. Nat. Mus. 1883.   The two species we place in this genus have hitherto stood one in Orthogonys, the other in Phœnicothraupis, each being an abnormal element in the genus in which it was located.  The two birds, Orthogonys olivaceus and Phœnicothraupis carmioli, are evidently nearly allied.  The general colour of the plumage is the same and the difference between the sexes slight.  In this respect they resemble Orthogonys viridis of Brazil  ...  The bill of Chlorothraupis differs from that of Phœnicothraupis in being rather more compressed, otherwise the shape is very similar.  But the great difference between the two is in the coloration of the plumage, olive-green being the prevalent colour in Chlorothraupis, whilst different shades of red distinguish the males of Phœnicothraupis, and of brown or ochraceous brown the females.  The males, too, are all ornamented with a scarlet crest." (Salvin & Godman 1883); "Phœnicothraupis carmioli Lawr.  ...  This species seems wrongly placed in Phœnicothraupis, the proportions being quite different from those of all the species of that genus.  Except in the form of the bill, which is much more compressed, it agrees better with Pyranga, while in many respects it comes very near to Orthogonys.  Since it should probably constitute a new genus, somewhat intermediate between the last two, I propose the generic name Chlorothraupis*  ...  *In their Biologia Centrali-Americana, Aves, Vol. I., p. 297 (December, 1883), Messrs. SALVIN & GODMAN have already adopted this name from my MS., quoting "Pr. U.S. Nat. Mus., 1883," the quotation in question having reference to the present article which was submitted for publication early in August, 1883.  Messrs. SALVIN & GODMAN include along with C. carmioli the Orthogonys olivaceus of Cassin; but my type of the genus Chlorothraupis is Phoenicothraupis carmioli Lawr." (Ridgway 1884).; "Chlorothraupis (Ridgway MS.) Salvin and Godman, Biol. Centr.-Amer., Aves, 1, p. 297, Dec., 1883—type, by subs. desig. (Ridgway, Proc. U. S. Nat. Mus., 6, "1883," p. 412, pub. April 11, 1884), Phoenicothraupis carmioli Lawrence." (Hellmayr, 1936, Cat. Birds Americas, Pt. IX, p. 297).
