Prevailing color above olive-green; the head and neck all round black, abruptly contrasted below with the white under parts; above passing insensibly into the green of the back; feathers of interscapular region obscurely dusky medially; sides and crissum rufous.

Edge of wing yellow; outer primary edged with whitish, edges of other primaries and of secondaries uniform olive-green. Fifth quill longest, fourth and sixth scarcely shorter; first shorter than ninth. Legs stout, claws much curved. Tail wanting in the single specimen before us (a male from the city of Mexico, belonging to Mr. G. N. Lawrence).

In describing this species, Swainson mentions an accompanying specimen as similar, but without any white spots on wings, suggesting that it may be the female. A specimen in the plumage from Oaxaca is characterized as follows.
