1917.] Chapman, Distribution of Bird-life in Colombia. 387 



Inhabits the Tropical Zone at the eastern base of the Eastern Andes. 

 There is much variation in the width of the frontal band of the male and 

 in the intensity of color in the female, but on the whole I can see no racial 

 differences in our series of thirty-five specimens, including examples from 

 Bolivia, eastern Ecuador, and the upper and lower Orinoco. A specimen 

 from the delta of the Orinoco has the frontal band narrow, but no narrower 

 than in one from Villavicencio. I have seen no British Guiana specimens.

 Hypocnemis elegans Sol., P. Z. S., 1857, p. 47 (Bogotd). 



Found by us only in the Tropical Zone of Amazonian Colombia. Our 

 females agree with an old ' Bogota ' skin. I have seen no topotypical speci- 

 mens of M. m. myiotherimis.

Inhabits the Tropical Zone of Amazonian Colombia. One of our two 

 females is brighter, the other agrees with two essentially topotypical fe- 

 males from Zamora, Ecuador.

 Javari). 



Found by us only in the Tropical Zone of Amazonian Colombia. Two 

 males differ from two others from La Union on the Lower Orinoco, in having 

 the head grayer, the lores black, instead of white, and the throat solid 

 black instead of white or black marked with white.
