(Thraupidae; Ϯ Black-chested Mountain Tanager C. eximia) Gr. κνημα knēma, κνηματος knēmatos  comb  < κναω knaō  to scrape; θραυπις thraupis  unknown small bird, perhaps a finch. In ornithology thraupis signifies tanager. "Cnemathraupis gen. nov.  Type.—Tanagra eximia Boissonneau.  Characters.—Bill similar to that of Buthraupis, but shorter; width at base less than depth and about equal to length of maxilla from nostril; length of maxilla from nostril about equal to or less than one half the distance from angle of mouth to tip; gonys strongly ascending and ridged terminally; nostrils less exposed than in Buthraupis.  Wing not so long as in Buthraupis, very little more than three and one half times the length of the tarsus; not so pointed, second (from outside) to seventh primaries longest, the first longer than the eighth (or ninth).  Tail comparatively longer than in Buthraupis, from three fourths to four fifths the length of the wing.  ...  Remarks:—Ridgway [1902] has suggested that the ridged condition of the gonys might be of generic importance.  This character, however, is found to be rather variable, being more pronounced in some specimens of C. e. chloronota than in others." (Penard 1919); "Cnemathraupis Penard,1 Auk, 36, p. 538, 1919  ...  1 I do not see any necessity for the generic separation of T. eximia, the existing structural divergencies being, in my opinion, good specific characters." ((Hellmayr, 1936, Cat. Birds Americas, Pt. IX, p. 190).
