Reading edition
Geothlypis poliocephala, var. caninucha, Ridgway.
The G. speciosa, Scl. (P. Z. 1858, 447; and Baird, Rev. 1864, p. 223), from Mexico, and G. semiflavus, Scl. (P. Z. S. 1860, 273, 291.—Baird, Rev. I, 1864, 223), from Ecuador, are species allied to G. trichas, and possibly referable to it. The original descriptions afford no tangible distinctive characters. It is barely possible, however, that they are distinct.
