The figure is the size of life. Bill black, depressed along the whole length, but more especially at the tip, which is rounded, thin, obtuse, and recurved in both mandibles; the under of which, towards the middle, has a convex swelling, which gives the recurvature a stronger appearance. All the upper plumage and body beneath golden-green; the throat, to the breast, shining with scale-like feathers of a vivid emerald-green. From the breast to the vent is a stripe of black down the middle; thighs white; tail even, the two middle feathers dull greenish-blue, the rest above obscure coppery-brown, but beneath of a rich shining topaz colour. I believe this bird is _unique_; I purchased it at Mr. Bullock's sale, and that gentleman received it from Peru. It presents so much of the genuine habit of the _Trochili_, that I have retained it under that genus; for, though the bill is differently formed, that exception does not point out any important difference from the general economy of those birds. * * * * * Pl. 106 [Illustration] CURSORIUS Temminckii, _Black-bellied Courier._ * * * * * GENERIC CHARACTER. _Rostrum mediocre, ad apicem compressum, mandibulis arcuatis, basi depressa, apice acuto, integro.
