JilolacUla riificapilla of Gmelin very probably refers to the same plumage of D. aestiva. At 

 any rate, it cannot interfere with MotaciUa palinarum, which has priority, and is undoubtedly 

 the present bird.

Sp. Ch.— Upper parts uniform grayish blue. Chin and throat orange yellow ; under parts white. Forehead and sometimes 

 most of crown, lore and cheeks, sides of the throat, and numerous streaks on the sides of the breast, black. A stripe from the 

 nostrils over and behind the eye, a crescent on the lower eyelid, the sides of the neck beliind the black clieek patch, and two 

 conspicuous bands on the wings, white. Terminal half of the outer webs of the outer two, and terminal third of the third tail 

 feathers, white. Female similar, but duller. Length, 5.10 ; wing, 2.60 ; tail, 2.30, (3322.) 



Hab. — Eastern United States as far as Pennsylvania and Ohio to the Missouri ; south to Mexico. 



This species appears subject to considerable variation. The bill varies greatly in length, 

 curve, and proportion, as does the size of body. Sometimes the forehead alone is black, at 

 others, as in 2386, 2913, almost the entire crown is black. The whole superciliary line is often 

 yellow anterior to the eye ; the forehead is sometimes divided by a short whitish line. In one 

 specimen from Washington, the black of the forehead is wanting ; the upper parts have a 

 brownish shade ; the under surface tinged with brown behind. It is considerably larger than 

 any other I have seen. 



As a general rule in the specimens before me, those from Georgia have the superciliary stripe 

 anterior to the eye yellow instead of white, as is the case in those from Ohio and Illinois.
