T h is species first occurred in a collection of birds from Bolivia, received by the Smithsonian Institution, and
submitted to Mr. G. N. Lawrence, who forthwith described it. It lias not since been met with in that
country, as far as we know; and it certainly was not obtained by Mr. Buckley. Several specimens,
however, were procured by Mr. Jelski in Western Peru, at Junin and Maraynioc.
I regret that nothing else has been published concerning this interesting species, which is easily
recognizable by its olivaceous-brown coloration.
I append the description originally given by Mr. L a w r e n c e 1“ Male. Entire upper plumage, including
the tail, dull bronzy olive-green; wings light bronzy purplish brown ; the gorget, of brilliant scale-like
feathers, is emerald-green on the chin, ending in more elongated feathers of fiery crimson, which terminate
with violet purple; under plumage dull brownish olive; vent light fulvous grey; under tail-coverts dull
bronzy olive-green, each feather margined narrowly with greyish fulvous; bill aud feet black. Length
5 i inches ; wing 31; tail 21; bill A .”
The figures in the Plate were drawn from the type specimen, lent to me by Mr. Lawrence.
