St. Ch. — Above uniform olive green ; tVie 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 tlie 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 the 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 back ai>pear to be in four series. There is a yellow crescent under the 

 eye, and below 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 bill, 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.
