Motacilla ruficapilla of Gmelin very probably refers to tbe same plumage of D. aestiva. At 
any rate, it cannot interfere with. Motacilla palmarum, 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 behind the black cheek 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.
