204 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. vieillote 
(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.
