The Tinamous are entirely confined to the new world, where they seem to hold the same scale in creation which the Partridges do in the old continent. Our knowledge of these singular birds has been much increased by the writings of Professor Temminck, who has described twelve species. The present bird is nearly the smallest of its family: I found it only once in the interior of Bahia in Brazil, where it must be very rare, or frequent to particular districts only. Though differing in some respects from the description of Temminck, I am inclined to consider it merely as a variety. Total length (excepting the legs) eight inches and a quarter. The bill is one inch one line long from the gape, and, with the irides, is red. The head and neck above blackish cinereous; the crown much darker and tinged with brown, the rest of the upper plumage uniform reddish-brown; the edges of the wing-covers tinged with pale cinereous; the spurious wings and quills greyish-brown; the chin is white, changing on the throat, neck, breast and their sides to a pale lead-colour, which, on the body, again becomes white; the feathers on the flanks are blackish or rufous, beautifully margined all round by white, with another internal mark of the same kind; those on the vent are similarly marked, but on a pale rufous ground; the thighs are rufous-white; the under tail-covers rufous, marked by narrow undulated concentric lines of black, the ends whitish. The length of the legs (from the knee to the base of the middle toe) one inch two lines, and from that to the tip of the claw one inch. Legs blueish-purple. Hind toe very short, and elevated above the ground. * * * * * Pl. 20 [Illustration] PICUS Braziliensis. _Brazilian Woodpecker._ * * * * * GENERIC CHARACTER.--See Pl. 14. * * * * * SPECIFIC CHARACTER. _P. olivaceus, subtus fulvus, nigrescente-fasciatus; capite subcristato, supra rubro, utrinque lineis olivaceis, fulvis, et rubris._ Olive Woodpecker: beneath fulvous, with transverse blackish bands.

It was, I believe, first described in a paper I sent to the Wernerian Society some time ago: the figure is less than the natural size.
