Sp. Ch. — Two black stripes on the crown separated by a median one of white. A broad supercili.ary stripe from the base of 

 the mandible to the occiput, yellow as far as the middle of the eye and white behind this. A broad black streak on the side of 

 the head from behind the eye. Chin white, abruptly defined against the dark ash of the sides of the head and upper part of 

 the breast, fadmg into white on the belly, and margined by a narrow black maxillary line. Edge of wing and axillaries 

 yellow. Back and edges of secondaries rufous brown, the former streaked with dark brown. Two narrow white bands across 

 the wing coverts. Length, 7 inches ; wing, 3.10 ; tail, 3.20. 



Ilah. — Eastern United States to the Missouri. 



Female smaller, and the colors rather duller. Immature and winter specimens have the 

 white chin patch less abruptly defined ; the white markings on the top and sides of the head 

 tinged with brown. Some specimens, apparently mature, show quite distinct streaks on the 

 brea.st and sides of throat and body. 



As Brisson's nomenclature is not binomial, and hi.s names merely literal translations into 

 Latin from the French vernacular, consisting usually of three or more words, rather than two, I 

 have followed Cabanis, Bonaparte, and most modern authors in rejecting them altogether.
