Sp. Cii. —Upper parts bluish ash ; a ring round the eye, with a line running to the nostrils, and the whole under part (except 
the tail coverts, which are white,) bright yellow. Centres of the feathers in the anterior half of the crown, the cheeks, con¬ 
tinuous with a line on the side of the neck'to the breast, and a series of spots across the fore part of the breast, black. Tail 
feathers unspotted. Female similar, with the black of the head and breast less distinct. In the young, obsolete. 
Length, 5.34; wing, 2.67 ; tail, 2.50. 
Hah. —Eastern United States to the Mississippi ; south to Guatemala.

specimens the outer primary is edged with white. 
I cannot find any tangible difference between the young bird or female of this species and the 
M. bonapartii of Audubon. Thus, in No. 2438, (female in autumn,) there is no black on the 
head, and scarcely any light line over the eye ; the first primary is conspicuously edged with
