the South American birds examined (including, besides those above 

 specified, a series from various localities in Venezuela and other sec- 

 tions of Colombia) certainly represent a form subspecifically distinct, 

 differing as they do in their much paler, duller yellow under parts, 

 grayer breasts, etc. Assuming that Brazilian and Colombian birds are 

 the same, von Pelzeln's name albivertex may be retained for this 

 southern form. 



The specimens from Minca, taken in June, are much duller than 

 those from Pueblo Viejo, shot in March; the difference is of course 

 entirely seasonal. But not even the freshest specirflens are as brightly 

 yellow below as the Costa Rican series. 



A rare bird in the lowlands, but common between 1,200 and 2,500 

 feet, wherever open or cultivated lands are found, preferring savannas 

 dotted with low trees. Mr. Brown secured one specimen at Chirua, at 

 " 7,000 feet," but the altitude here assigned is clearly a mistake. Like 

 all of the genus, this species is largely a fruit-eater.

Eighteen specimens : Bonda, Minca, Cincinnati, La Tigrera, Tierra 

 Nueva, and Fundacion. 



These agree with specimens from other parts of the range of the 

 species in northern South America, and run through the same varia- 

 tions in color according to season, worn breeding birds always being 

 duller than those in fresh plumage. 



This Elcenia ranges from near sea-level up to 4,000 feet, but is 

 more common between 1,000 and 2,500 feet. Its haunts and habits are 

 practically the same as those of E. chiriquensis albivertex. Dr. Allen
