 lars, tertials, rump feathers, and upper tail -coverts, the tips also) 

 brownish gray, becoming browner (on some feathers, especially wing-

 brownish, the darker centers to feathers mostly concealed; edge of 

 wing light yellow; tail brownish dusky, the feathers edged with 

 lighter; lores, narrow orbital ring, malar stripe, chin, throat, and

^ Three specimens. 



^ Two adult males in the collection of Messrs. Salvin and Godman from El Yolcan, 

 Chirtandega, Nicaragua (April 28), 1 refer somewhat doubtfully to this form. They 

 are larger and slightly different in color, but this may result from the fact that both 

 are in very good plumage, while the type, from Huatusco, and all the Palenque 

 specimens are decidedly worn. Measurements are as follows:
