brought together. Western females have the parts which are of 

 an ashen color in the Eastern bird of a yellowish brown ; and this 

 striking difference pertains to all Western birds, as well as to 

 those from Mexico. I am unable to detect any marked difference 

 between specimens from British Columbia and the northwestern 

 United States, and those from the Valley of Mexico and the high- 

 lands of Vera Cruz. Specimens before me from British Colum- 

 bia, Washington, Oregon, California, Utah, Arizona, New Mexico, 

 Valley of Mexico, and Mirador (near Vera Cruz), are all exam- 

 ples of the western subspecies, which must be called montana, 

 that name having been applied by Mr. Ridgway to the Evening 

 Grosbeak inhabiting the southern Rocky Mountains of the United 

 States and thence southward through the highlands of Mexico 

 into Central America, although none of the characters assigned by 

 him are adequate to separate the Western bird from that of the 

 Great Lake region, the diagnosis having been based on the char- 

 acters of the male, and the describer's intention having been 

 to separate from the northern bird at large that inhabiting 

 Mexico and the southern Rocky Mountain region, as shown by 

 his assignment of habitats to the two forms: "Hab. (Var. 

 vespertina) : Pacific coast to Rocky Mountains ; northern 

 America east to Lake Superior. ( Var. tnontana ) : Southern 

 Rocky Mountains of United States into Mexico ; Orizaba ! 

 (Sclater, i860, 251) ; Vera Cruz (alpine regions, breeding) 

 Sumichrast, Pr. Bost. Soc, I, 550; Guatemala, Salvin." As 

 the subspecies montana has been dropped, not appearing in the 

 A. O. U. Check-List nor in Mr. Ridgway's Manual of North 

 American Birds, the characters on which it was based having 

 been shown to be inconstant, I have enumerated it in the present 

 article as new, since here first described, retaining Mr. Ridgway's 

 name, his type, from Cantonment Burgwin, New Mexico, being 

 an example of the new subspecies. 



Adult Male (Type, No. 11,960, U. S. National Museum, collected by 

 W. W. Anderson, at Cantonment Burgwin, New Mexico, June 3, 1S59) '-~~ 

 Indistinguishable from northeastern specimens of true C vespertina. 



AcTult Female (Type, No. 4163, Coll. E. A. Mearns, Oak Creek, near 

 Fort Verde, Yavapai County, Arizona, August 14, 1SS5) : — Pattern of 

 markings as in C. vespertina, but the color of most of the body is brown, 

 mixed with olive yellow, and tinged with gray, instead of being wholly 

 grayish as in vespertina. The black stripe at each side of the throat and
