ASG£ 
Specimens vary somewhat in purity of tints, and especially in in- 
tensity of yellow of under parts, which color is deeper in autumnal 
skins. 
I regret that I led Mr. Sclater into an error by informing him that 
the Vireo subsequently described by him as V. cobanensis was differ- 
ent from V. philadelphica. The skin forwarded for examination by 
him appeared to differ in some noticeable points, but those subse- 
quently received from Mr. Salvin and other sources agree exactly 
with specimens from Wisconsin and Hudson’s Bay.
