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 ren^retthat I led Mr. Sclater into an error by informing? him that 

 the Vireo subseciuently described by him as V. cobanenais was dill'er- 

 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. 



(18,972.) Type of V. eobanensU. (3.3,300.) Iris brown.
