Hab. Cordilleras Mountains, on the Kiver Truando,New Granada. Discov- 

 ered by Mr. W. S. Wood, Jr., and Mr. C. J. Wood, attached to U. S. Expedition 

 for surveying the River Atrato, in command of Lieut. N. Michler, U. S. Topog. 

 Engineers. Spec, in Nat. Mus., Washington. 



This is a curious bird and has not a little puzzled the present writer. My 

 impression is that it is an undescribed genus related to Icteria and more so to 

 Orthogonys and not unlike some species of Pyranga. At present I rate it as an 

 Orlhogonys to which it quite as much belongs as Pyranga cyanictera of authors 

 at least, of which there are several specimens in the Academy collection. 



Mr. C. J. Wood states that this bird inhabits low trees and bushes in the 

 Cordilleras, on the Rio Truando, and could be constantly heard at some local- 

 ities, though not so easily seen. Its notes are loud and much varied, bearing a 

 general resemblance to those of the Chat of North America {Icteria viridis). It 

 appeared to be very active and lively, constantly flying about the bushes and 

 changing its position.
