Sp. Ch. — Upper parts and cheeks olive green, brightest on the rump ; the wings, tail, and upper tail coverts, in part, bluish 

 gray. An intensely black patch from the blue-black bill to the eye, continued a short distance behind it. Crown, except 

 behind, and the under parts generally, rich orange yellow. The inner wing and under tail coverts white. Eyelids, and a short 

 line above and behind the eye, brighter yellow. Wing with two white bands. Two outer tail feathers with most of the inner 

 web, third one with a spot at the end while. Female and young similar, duller, with more olivaceous on the crown. 

 Length, 4.50 ; wing, 2.40 ; tail, 2.10. 



Hab. — Eastern United States to the Missouri ; south to Guatemala. 



The bill in this species is conical and very acute, shorter than the head. The <irst four quills 

 are nearly equal and considerably longest. The tail is emarginate and slightly rounded. 



This species is somewhat like Froionotaria citrea, though much smaller. The yellow of the 

 head is limited to the fore part of the crown. The black band to the eye and the white on the 

 ■wing are not found in the other species. 



The summer or autumnal plumage of this species agrees quite well with the description of 

 Sylvia inontana of Wilson, in everything but the streaks on the sides of the body. 



As this species is unquestionably Certhia pimis of Linnaeus, it becomes necessary to restore 

 his specific name, instead of using solitaria of Wilson.
