The above description is taken frnin a type specimen received from Mr. 

 Audubon, and represent i l!>.e average si)ring plumage. Autumnal skins are 

 rather brighter, and there is occasionally an oclSaceous tinge on the white 

 of the under parts. 



This species at first siglit ajipears like a miniature of V. ffi/rii.9, the head 

 being almost; exactly similar. The back is, however, much brigiiter olive, 

 the sides and crissum deejjer yellow. The superciliary light strijie is sliorter.

 feet are entirely tlifl'erent in their projjortions.
