portions of the quills. The bill is considerably stouter than in C. erythrophtlialmus. There 
is no difference between the sexes, except that of size. It goes as far north in summer as 
Labrador, according to Mr. Audubon, and stragglers have been occasionally taken in Europe. 
Although Townsend says it occurs west of the Rocky mountains, it has not been collected by 
any of the recent expeditions.

Erythrophrys erythrophtlialmus, Bon. List, 1838. 
Coccyzus dominions (Lath.) Nutt. Man. I, 1832, 556, (not of Latham, which belongs rather to C. americanus, on 
account of the red qnills and white edge of outer tail feather.) 
Sp. Ch. — Bill entirely black. Upper parts generally of a metallic greenish olive, ashy towards the base of the bill; 
beneath pure white, with a brownish yellow tinge on the throat. Inner webs of the quills tinged with cinnamon. Under 
surface of all the tail feathers hoary ash gray. All, except the central on either side, suffused with darker to the short, bluish- 
white, and not well denned tip. A naked, red skin round the eye. Length about 12 inches ; wing, 5 ; tail, 6.50. 
Hab. — United States to the Missouri plains. 
This species differs from the C. americanus in the black bill, and the absence of black on the tail 
feathers, the white tips of which are much shorter and less abruptly defined. One specimen 
(5253) from the Upper Missouri has a much stronger tinge of yellowish cinnamon on the inner 
webs of the quills than the others. The sexes are quite similar.
