ends of primaries. It is possible that this may be an extraneous 

 feature, as it has somewhat the appearance of a stain, and is not 

 mentioned by Sclater. The chin and throat are rather more yellow- 

 ish. There is, as far as I can see, no specific difference between 

 this specimen and the others, the yellow of under parts, if anything, 

 being there the deepest. The original description and figure, from 

 an Ecuador (Pallatanga) series, represent the under parts as much 

 whiter than in the present specimens, and it is barely possible that 

 two species may be involved. 



This species is markedly different from any other, and scarcely 

 needs comparison. The proportions of quills are quite peculiar, and 

 the brown cap, with the olive back is decidedly unicpie. In general 

 form it constitutes a transition from V. gilva to V. noveboracensis.
