" Iris ; First quill spurious ; not quite half the 2d, which is about equal to the 8th ; 3d and 4th quills longest; 5th scarcely shorter. Tail nearly even, or a little rounded, the feathers narrow.

Total length, ; wing, ; tail, ; exposed portion of 1st primary ..60, of 2d, , of longest, 3d (measured from exposed base of 1st primary), ; 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.
