Sp. Char. (229, Salvin collection.) Head and body above black, the feathers with olive-green edges, especially on the back, obscuring the ground-color; rump clear black. Entire side of head (extending to nostrils and on lower jaw), and the partially concealed bases of the feathers on the median line of the forehead, yellow, with a narrow black line
from lores, through the eye, widening behind, but not crossing through the yellow.

Feathers of crissum with black centres. Wings above ashy, with two white bands across the coverts, the scapulars streaked with blackish; first quill edged externally with white, the rest with gray. Tail-feathers blackish, edged externally with ashy, the lateral with white at the base. Outer tail-feather white on the inner web, except a stripe along the shaft near the end; second similar, but the white not reaching so far towards the base; third with a short patch of white in the end. Bill and legs brownish-black. Bill unusually thick. Length, 4.50; wing, 2.50; tail, 2.40; tarsus, 2.75.
Hab. Vera Paz, Guatemala; San Antonio, and Medina River, Texas. (Heermann and Dresser.)
The capture of specimens of this species at San Antonio, Texas, by Dr. Heermann, and on the Medina River by Mr. Dresser, entitles it to a place in our fauna. The specimen described above is Mr. Salvin’s type.
Habits. A single specimen is said to have been taken near San Antonio, Texas, by Dr. Heermann. It is thought to be probably a bird belonging to the fauna of Arizona and New Mexico, and is given hypothetically by Dr. Cooper among the birds of California. In its appearance it resembles D. virens, D. townsendii, and D. occidentalis. It was originally described by Salvin from a single specimen obtained in Guatemala. Another pair was afterward obtained by Mr. Salvin on the highest point of the road between Salama and Tactic. In regard to its habits, nothing is on record.
