Description.—Above dark olive-green; head dark cinereous, slightly crested, with a large basal spot of bright yellow; lores and eye-region mixed with whitish; wings and tail ashy black, with slight margins of the same colour as the back; below pale cinereous; belly, crissum, and under wing-coverts sulphur-yellow; bill blackish; feet dark brown: whole length 5·0 inches, wing 2·5, tail 2·5. Female similar.
Hab. South America.
The Elainea grata, based by Dr. Cabanis upon specimens obtained by Herr Schulz in Tucuman, must, I think, be identical with Azara’s Contramaestre pardo verdoso, corona amarilla, upon which Vieillot established his Sylvia viridicata. It is certainly, in my opinion, the Muscicapara viridicata of d’Orbigny.
Herr Schulz met with this species in the province of Tucuman, in the month of December.
