 much reduced; wings elongated, pointed, much longer than the tail; the first quill 

 nearly or quite the longest; tail very slightly rounded; tail feathers acuminate, 

 pointed ; the under coverts reaching to within less than half an inch of their tip ; 

 tarsi elongated, longer than the head; claws large, the hinder one as long as its digit,

DESCRIPTION. 



Upper parts and sides of the body uniform olive-green, very slightly tinged with 

 ash on the crown; sides of the head ash, tinged with dusky beneath the eye (entire 

 head sometimes ash); chin and throat grayish-ash, gradually becoming darker to 

 the upper part ot the breast, where it becomes tinged with dark-ash ; sides of the 

 neck, breast, and body olive, like the back; rest of under parts light-yellow; a 

 broad, continuous white ring round the eye; wings and tail feathers olive (especially 

 the latter), without any trace of bars or spots ; bill brown above ; feet yellow. 



Length, six inches ; wing, three ; tail, two and twenty-five one-hundredths. 



This is another very rare bird in New England, and I 

 have never met with a specimen that was taken north of 

 Massachusetts. In West Roxbury, of this State, in a large 

 tract of pine forest, two or three specimens have been taken 

 within as many years. So far as I can learn, this species 

 has all the habits and motions of the two preceding. It 

 has no song, but utters the note queet often, and in a 

 sprightly tone, as it searches among the shrubbery for its 

 favorite food of spiders and small caterpillars. 



ICTERIA, VIEILLOT. 



Icteria, VIEILLOT, Ois. Am. Sept. I., (1790) 85. 



Bill shorter than the head ; broad at the base, but rapidly becoming compressed 

 or much higher than broad, with the ridge elevated and sharp from the very base 

 of the bill; the upper outline much curved throughout; the commissure less curved,
