pale, the latter smaller, and the claws more curved than in any other known species; crown with a pale rufous tinge. Length, 7.50; wings, 3.50; tail, 4.00; tarsus, .90; middle toe and claw the same; hinder toe, .65. Rather smaller than maculata.”

Pipilo albicollis, Sclater. Above uniform olivaceous-brown; the cap not differently colored. Lores, chin, and throat white, the two last bordered and defined by dusky spots; jugulum and breast white, the former clouded with olivaceous, and with a dusky blotch in middle; middle of throat crossed by an olivaceous band which curves round on each side under the ear-coverts; sides grayish. Flanks behind, anal region, and crissum, rufous. Middle wing-coverts with a whitish bar across their tips. Fourth and fifth quills longest; first shorter than ninth and secondaries. Length, 7.00; wing, 3.30; tail, 3.70. Bill and legs light. Hab. Central Mexico.
This “species” may fairly be considered as one extreme of the series of which P. crissalis is the other; and differs from the rest merely in a greater amount of white, and the absence of rufous tinge on top of head. The fulvous of throat is concentrated in a band across its middle portion, leaving chin and lower throat white; this, however, is foreshadowed in the paler chin of mesoleucus, and the whitish lower throat of albigula. The uniformity of coloring above is nearly equalled by that of P. crissalis. The whitish band across the middle wing-coverts is the most positive character.

A specimen from Cleveland, Ohio (7,429 ♀, April 1, Dr. Kirtland), and one from Washington, D. C. (28,246 ♂, Feb.), have nearly as distinct streaks above, but the white of lower parts is without any tinge of yellow.
