to the base of the middle claw ; the outer falling short of it. Second and third quills longest. 

 Tail much as in (Jolumha. 



Dark slaty blue. Top of the head white. Sides of neck with golden green scales. Bill 



dusky in the skin P. leucocephalus. 



The sub-genus Columba, as characterized above, includes the C. livia, or domestic pigeon, the 

 differences between it and the American forms being very slight. Reichenbach and Bonaparte 

 separate the North American birds from Columba, under the name of Chloroenas.

Sp. Ch. — Above olivaceous tinged with ash, changing on the wing coverts to bluish ash, of which color are the hinder part 

 of the back, rump, and basal portion of the tail. The terminal third of the tail is whitish brown, with a tinge of ash, succeeding 

 a narrow bar of dusky. Head all round, sides of neck and under parts, including tibia, purplish violet; the middle of the 

 abdomen, anal region, and crissum, whitish. Tibia and throat tinged with blue. Quills brown, narrowly margined with 

 white. A conspicuous narrow half collar of white on the nape ; the feathers below this to the upper part of the back metallic 

 golden green. Bill and feet yellow ; the former black at tip. 



Female similar, with less purple ; the nucbal collar of white, obsolete or wanting. 



Length about 15 inches; wing, 8.80 ; tail, 6.10. 



Hab. — From Rocky mountains to Pacific coast ; south to New Leon, Mexico. 



There is a strong tinge of bluish in the purplish violet around the base of the bill. The 

 sides of body and inside of the wings are bluish ash like the rump. The outer edges of the greater 

 wing coverts change to whitish. The subterminal band of blackish on the tail is about an inch 

 wide, and some two inches from the tip. It is scarcely appreciable on the under surface. The 

 whitish ash at the end of the tail is often much soiled with brownish. 



The female sometimes has a distinct nuchal collar, but without extending as far round the neck. 



This species was at one time supposed to occur in Chile, but it is there represented by a distinct 

 though closely allied species.
