Distinguishing Characters. — Bill slightly decurved; c? with the forehead, 

 throat, or, at least, chin yellow, the breast "black ; ? with forehead more or less 

 tinged with yellow, the feathers of the crown wholly gray. The young 5, with

 entirely gray crown- feathers, and white crissum; while the Tennessee Warbler 

 is greener above with the head the same color as the back. The t? apparently 

 does not acquire mature plumage until the second year. Length (skin), 4.40;
