Eab. Central regions of the United States, to Mexico. Cape St. Lucas. Not 

 recorded from Pacific slope. 



Mexican specimens seem to differ in having the under tail coverts 

 more distinctly and broadly banded ; the outer primary half the 

 longest, instead of being considerably less than half. My materials, 

 however (two skins), are not suflBcient to decide whether these differ- 

 ences are characteristic, and accompanied by any others. 



Young birds, fully grown, differ from adults in the entire absence 

 of any marking on the under surface, not even on the crissum. 



A specimen from Cape St. Lucas is decidedly smaller than the 

 more northern ones. 



No specimens have been received from the Pacific slope of Cali- 

 fornia, excepting from Fort Tejon, which is near the dividing line. 

 Dr. Heermann speaks of its being common throughout California.
