Sp. Ch. — Above uniform olive green ; the middle of the back streaked with brownish red. Under parts and sides of the 
head, including a broad superciliary line from the nostrils to a little behind the eye, bright yellow, brightest anteriorly. A well 
defined narrow stripe from the commissure of the mouth through the eye, and another from the same point curving gently 
below it, also a series of streaks on each side of the body, extending from tho throat to the flanks, black. Quills and tail feathers 
brown, edged with white ; the terminal half of the inner web of the first and second tail feathers white. Two yellowish bands 
on the wings. Female similar, but duller. The dorsal streaks indistinct. Length, 4.86 ; wing, 2.25 ; tail, 2.10. 
Hub. — Atlantic States, as far north as New York. 
The streaks on the hack appear to he in four series. There is a yellow crescent under the 
eye, and helow this the black one already mentioned. After a slight interval the stripes on the 
side of the throat begin, in one series on each side ; two, however, starting on the breast. The 
yellow superciliary stripe extends to the base of the hill, although those of opposite sides do 
not coalesce. Sometimes there is a black line, bordering the olivaceous of the crown, anteriorly. 
In this species the second, third, and fourth quills are longest ; the first rather longer than 
the fifth. The tail is considerably rounded, in fact, almost graduated. The bill is dark brown.
