Chalybura urochrysa Hbllm., P. Z. S., 1911, p. 1184 (Sipi; N6vita; Condoto; 

 Rio Cajon). 



Occurs throughout the Tropical Zone of the Pacific coast and eastward 

 into Antioquia. While our specimens from Alto Bonito show no approach 

 toward C. isauroe, of which we have a large series from eastern Panama 

 (21) the latter appears to be the Panama representative of the Colombian 

 bird. This probability added to the absence of authentic specimens from 

 Panama makes it doubtful if urochrysa is found north of Colombia.

Found by us only in open places in the Subtropical Zone. With the 

 exception of a male from Cerro Munchique, all our specimens are from the 

 Central Andes. The presence or absence of a violet or purple tinge on the 

 abdomen, appears to be individual and is possibly due to age. The under 

 tail-coverts, in our series, average more buffy than in a series from Merida, 

 Venezuela. However, in some Colombian specimens the buff is reduced to a 

 minimum, while, on the other hand, the specimen which has the huffiest 

 under tail-coverts can be essentially matched by a Merida specimen. I can- 

 not feel, therefore, that, so far as our series is concerned, this character is of 

 diagnostic value. I am unable to appreciate the validity of the characters 

 assigned to the Costa Rican bird "Petasophora cahanidis Heine" and thus 

 agree with Ridgway (Bull. U. S. N. M., 50, p. 484).
