BIRDS OF WESTERX COLOMBIA. 1119 



Observations. As already stated by Dr. Sclater and more 

 recently by Salvadovi and^Festa, birds from Eastern Ecuador 

 are easily recognizable by the reddLsh-orange shoulder- .spot and 

 the dai-k brownish-olive colour of the upper parts. From the 

 remarks of Berlepsch and Taczanow.ski it is evident that the 

 specimens from Huambo. X. Peru, belong to the same race.
