BIRDS OF WESTERN COLOMBIA. 1129 



wings and tail, less developed crest, more rufescent brown colour 

 of the upper parts, and especially in having distinct, ochraceous- 

 buff apical edges to the greater wing-coverts. An unsexed bird 

 obtained at Santa Rita, W. Ecuador, by Buckley's collector 

 Yillagomez, and two skins, one marked " c? ," from Panama, 

 " McLeannan leg.," in the British Museum, are also immature. 

 They were erroneously referred by Dr. Sclater to the Peruvian 

 race C. s. minor, the type of which is likewise a young bird ! 



However, adult males from Chamicuros (the type locality of 

 C. minor) differ slightly from those of Western Ecuador and 

 Colombia (Remedios) in having both upper and under surfaces 

 ' rather paler brown. An adult male obtained on the Rio Purus, 

 W. Brazil, shows the same variation when compared with our 

 Choco series. Hence the name C. s. minor may well be 

 retained for the Amazonian race, though its (rather trifling) 

 characters should be confirmed by a better series of fresh skins. 



According to my views there are two very closely allied races : — 



(1) C. s. suhhrunneus Scl., ranging from S.W. Ecuador 



through Western Colombia to Panama. 



(2) C. s. minor Scl., ranging from Eastern Peru (Chami- 



curos) to W. Brazil (Rio Puriis). 



Their synonymy and ranges are as follows :-
