1917.] Chapman, Distribution of Bird-life in Colombia. 449 



Char, suhsp. — In general coloration most nearly resembling M. o. hederaceus 

 Bangs, but with less yellow in the plumage, the back, therefore, bluer green, the 

 breast-streaks whiter, the belly paler. 



Known only from two specimens collected at Buena Vista. 



(2892) Pipromorpha oleaginea oleaginea (Licht.). 

 Muscicapa oleaginea Light., Verz. Doubl., 1823, p. 55 (Bahia). 



Specimens from Florencia and Villavicencio agree and represent the 

 dark-bellied, Brazilian form which is markedly different from the more 

 northern parca. I have, however, no topotypical Bahian birds for com- 

 parison. Suapure, Venezuela, birds agree with those from eastern Colom- 

 bia, but Trinidad examples appear to be intermediate. 



Villavicencio, 2; Florencia, 2. 



'■ ' (2892a) Pipromorpha oleaginea parca (Bangs). 



Mionecies oleagineus parous Bangs, Proe. N. E. Zool. Club, 1900, p. 20 (Panama). 



Mionectes oleagineus ScL. & Saiv., P. Z. S., 1879, p. 512 (Remedios); Allen, 



Bull. A. M. N. H., XIII, 1900, p. 149 (Bonda; Minca; Cacagualito; Santa Marta). 



Specimens from the Lower Cauca and Magdalena Valleys agree with 

 those from Panama and Santa Marta, and are much paler, especially below, 

 than those from the eastern base of the Andes which are referable to true 

 oleaginea. 



Puerto Valdivia, 2; Honda, 1; Chicoral, 2; Andalucia, 1. 



(2896) Leptopogon superciliaris poliocephalus Cab. & Hein. 



Leptopogon poliocephalus Cab. & Hein., Mus. Hein., II, 1859, p. 55 (Bogota). 

 Leptopogon superciliaris poliocephalus Hellm., P. Z. S., 1911, p. 1132 (N6vita; 

 San Pablo, 4500 ft.). 



Occurs in all three ranges and in both Tropical and Subtropical Zones, 

 but our material does not satisfactorily determine its zonal distribution. 

 In default of topotypical (Peruvian) specimens, I follow von Berlepsch 

 (Int. Orn. Cong., 1907, p. 492) in recognizing the Colombian bird as sub- 

 specifically distinct. From a Yungas, Bolivia, example, our Colombian 

 birds differ in being much brighter yellow throughout, the belly being canary 

 instead of yellowish gray. Two birds from Guacharo, northeast Venezuela, 

 agree with Colombian specimens, but two Guatemalan specimens are much 

 smaller. 



Alto Bonito, 1; Dabeiba, 2; Peque, 1; Cocal, 1; Miraflores, 2; Buena 

 Vista, 2; Villavicencio, 2.
