oleaginea as he understood that form, but Mr. Ridgway referred both these 

 and Santa Marta examples to the new race without hesitation, and we 

 agree in this conclusion. It is true that specimens from interior and 

 western Colombia differ from the Santa Marta series in being slightly 

 darker, both above and below, verging thus toward pallidiventris, with 

 which, however, the present form can not directly intergrade, since there 

 is a long stretch of country in northern Venezuela from which no form of 

 the group is at present known. 



A single specimen from La Colorada, Colombia, east of the Eastern 

 Andes, is referred here provisionally, but a series from this locality might 

 tell a different story. The present race is also sufficiently well contrasted 

 with the dull-colored Ecuador form. 



In Juvenal dress (illustrated by No. 97,812, Collection American Museum 

 of Natural History, Cacagualito, Colombia, May 12) the colors are all 

 duller, and the under parts more rufescent. In fresh plumage the colors 

 tend to be a little deeper in tone. Out of ninety-eight specimens examined 

 in this connection, only fourteen have the outer primaries sufficiently 

 narrowed at the tips to be noticeable. 



Dr. Stone describes a nest found by the late Mr. L. L. Jewel in the Canal 

 Zone as "a long pear-shaped structure with entrance on the side, made of 

 green moss and fine grasses. Eggs three, pure white, .58 x .78, .57 x .76, 

 and .56 X .75 in."
