Found by us only on the subtropical slopes arising from the Magda- 

 lena Valley. Our specimens average considerably darker and more oli- 

 vaceous below and have smaller caps than four from Zaruma, Ecuador.

Inhabits the Subtropical Zone of the Western Andes. An immature 

 bird from Ricaurte has the middle pair of tail feathers chiefly of the 

 color of the back and, therefore, approaches the Ecuadorian erythrops, of 

 which I have no specimens. This specimen is in the plumage of the type 

 of S. e. rufigenis, having the superciliary, sides of the head and underparts 

 rich ochraceous.

Inhabits the subtropical slopes above the Magdalena Valley. A speci- 

 men from La Palma is decidedly more fulvous below than one from Fusu- 

 gasuga and two Bogota skins. Doubtless this interesting little species will 

 some day be generically separated from Siptornis.

Char, suhsp. — Similar to S. f. flammulata (Jard.) of Ecuador but upperparts 

 browner, the front part of the crown richer and deeper in tone, hazel rather than 

 ochraoeous-tawny, with, as a rule, the shaft-streaks broader, the margins corre-
