Bill shorter than the head. Above reddish-brown, darker towards the head, brighter on the rump. The feathers everywhere, except on the head and neck, barred with dusky; obscurely so on the back, and still less on the rump. All the tail-feathers barred from the base; the contrast more vivid on the exterior one. Beneath pale fulvous-white, tinged with light brownish across the breast; the posterior parts rather dark brown, obscurely banded. Under tail-coverts whitish, with dusky bars. An indistinct line over the eye, eyelids, and loral region, whitish. Cheeks brown, streaked with whitish. Length, 4.90; wing, 2.08; tail, 2.00. HAB. Eastern Province of the United States, from Atlantic to the Missouri River. In the Review of American Birds (p. 139), I have established a variety, _aztecus_, to embrace specimens from Mexico paler than _ædon_, and with a brownish tinge on the breast, and smaller size. There can scarcely be any doubt that the _T. americanus_ of Audubon is nothing more than this species in dark, accidentally soiled plumage (from charcoal of burnt trees, etc.).
