Median portion of rump feathers 

 Bill horn-color above, pale below. Legs plum- 



vlit'; the sides, axillars, and crissum pale yellow (sides of lower, neck 

 ;..! 1 of breast glossed with olivaceous), faintest on the longer feathers of the 

 latter. Two rather nar- 

 row bands on the wing 

 coverts, and the outer 

 edges of innermost se- 

 condaries white ; the 

 other quills edged with 

 faded olivaceous. Inner 

 edges of quills whitish. 

 Tail feathers brown, ]-, 



edged externally with 

 o:ive; internally fading into paler brown, 

 concealed pale yellowish, 

 beous. " Iris brown." 



First quill spurious ; not quite half the 2d, which is about equal to the 8th ; 

 3il and 4th quills longest ; 5th scarcely shorter. Tail nearly even, or a little 

 rounded, the feathers narrow. 



(No. 1,926.) Total length, 4.20; wing, 2.18; tail, 1.90; exposed portion 

 of 1st primary .60, of 2d, 1.32, of longest, 3d (measured from exposed base 

 of 1st primary), 1.60 ; length of bill from forehead, .51, from nostril, .28, along 

 gape, .60 ; tarsus, .75 ; middle toe and claw, .54; hind toe and claw, .42. 



The above description is taken from a type specimen received from 

 Mr. Audubon, and represents the average spring plumage. Autum- 

 nal skins are rather brighter, and there is occasionally an ochraceous 

 tinge on the white of the under parts. 



This species at first sight appears like a miniature of V. gilvus, 

 the head being almost exactly similar. The back is, however, much 

 brighter olive, the sides and crissum deeper yellow. The superciliary 

 light stripe is shorter. The white markings of the wings are want- 

 ing in gilvus. The wing, tail, and feet are entirely different in their 

 proportions.
