Remark. — Rather larger in all its measurements than 0. Virginia 

 ana. From the general appearance of this bird, Mr. Gould is led to 

 believe that it may hereafter prove to be a variety of some other 

 species, probably of 0. Virginiana ; at the same time its markings are 

 so diff^erent and so decided in character that he has deemed it best 

 to describe it provisionally, under a distinct appellation.
