+Chloronerpes affinis+, _Scl. et Salv. Nomencl._ p. 99; _White, P. Z.
S._ 1882, p. 617 (Salta).
_Description._--Above dull olive-green, with fine yellowish
shaft-spots; wings and tail black, spotted with white; head black,
bordered behind by a yellow nuchal collar, front of head with white
shaft-spots, hinder half with scarlet ends to the feathers: beneath
greyish white, with narrow black cross bands; under surface of wings
white, barred with black: whole length 6·5 inches, wing 3·7, tail
2·4. _Female_ similar, but without any red on the nape.

White identified a pair of birds obtained at Campo Santo, in Salta, as
belonging to this species, but his determination requires confirmation,
as there are several forms of this genus nearly alike which require
accurate discrimination.
