A series of specimens of this species exhibits considerable diversities. Some skins from Mirador, Mex., not far from Vera Cruz, perhaps best represent the species as first described by Wagler. In these the head and neck are sooty-brown, becoming lighter on the jugulum and on the back. The wings and tail show a trace of dull bluish. In No. 23,915 the under parts are sooty-gray, the bill and legs black; in 23,916 the colors are similar,

with a fulvous tinge on the breast, the bill and feet yellow. In both the under surface of tail is brown to the end. In 23,917 the under parts, from breast to crissum inclusive, with the tibiæ, are brownish-white, the tail-feathers (excepting the two median) tipped with white for over an inch, the bill and feet black. This one also has an obscure dull bluish wash or patch along the feathers of the ramus of lower jaw not observed in other specimens.
