REVIEW OF AMERICAN BIRDS. 



[part I. 



longer than the 5th, not shorter. The quills are more broadly 

 margined than in that species, and all the colors more brilliant. The 

 entirely red head will readily distinguish it however. The reddish 

 streaks in the feathers of the chin, and a tinge of the same in the 

 lores, will distinguish the female bird from all others. 



The preceding remarks were based upon the types of D. vieilloti 

 (all from Lt. Michler's collection), as described by Mr. Cassin. 

 Since then I have had the opportunity of examining specimens from 

 other localities. A series from Mazatlan exhibits some differences, 

 but the specimens are all moulting, and it is impossible to determine 

 their true characters. It is, however, quite in accordance with the 

 general rule in the distribution of American birds, that a species 

 inhabiting the main land of South America should be replaced 

 farther north, especially so far as Mazatlan, by a second, closely 

 allied to it. To which form, if there be two, the ruficeps of Cabanis 

 belongs, it is difficult to say, as his description refers equally to 

 specimens before him from Carthagena, Costa Rica, and Mexico ; 

 most probably, however, to the former, and as such true synonyms 

 of D. vieilloti.
