Our specimens of this seemingly not common species are from the Sub- 

 tropical Zone of the Western and Eastern Andes. We lack topotypical 

 specimens.

Pipreola riefferi ScL. & Salv., P. Z. S., 1879, p. 519 (Retire; Medellin; Sta. 

 Elena). 



Found in the Subtropical Zone of the Eastern and north Central Andes. 

 Specimens from the Bogota region are topotypical. Two males from El 

 Eden, on the east slope of the Central Andes, and three from Sta. Elena 

 are intermediate but nearer to riefferi than to occidentalis. I cannot place 

 a female from Salento but the form of that locality is probably occidentalis.

Euchlornis riefferi occidentalis Chapm., Bull. A. M. N. H., XXXIII, 1914, p. 630 

 (San Antonio, Col.). 



Char, suhsp. — Similar to E. r. riefferi but head, throat and breast blacker, the 

 black of the head more sharply defined from the green back; closely resembling E. r. 

 melanolcema in the color of the parts named but the wing-coverts and tertials less 

 conspicuously tipped, black areas of these feathers less clearly defined and differently 

 shaped. 



Common in the Subtropical Zone of the Western Andes but apparently 

 less numerous in the Central Andes. Females from Almaguer and Salento 

 doubtless should be referred to this race.
