116 Brisuop, New Birds from Alaska. Aca 
nostril, .38-46 (average .41); width of bill at base, .28-33 (average .31) 
inches. 
Measurements of fifteen specimens of Sayornis saya.— Wing, 3.67-4.27 
(average 4.08); tail, 3.03-3.59 (average 3.27); culmen, .75-.83 (average 
80); bill from nostril .42-48 (average .45); width of bill at base .27-.34 
(average .30) inches. 
Remarks. — Sayornis saya (Bonap.) is separable into two well- 
marked races, as described above: saya, a paler, rather scorched 
appearing bird with shorter tail and longer bill, living in Calli- 
fornia, Lower California, Nevada, Utah, Arizona, Colorado, New 
Mexico, Mexico and north to Fort Laramie, Wyoming, from all 
of which localities specimens in the above measured series have 
been selected; and yuwkonensis, a darker, clearer gray bird, with 
longer tail and shorter bill, of which besides our Yukon series of 
eleven specimens, only two of them adults, and winter birds from 
Texas, I have only seen one typical bird, which was taken at Fort 
Klamath, Oregon, September 20, 1882, by Captain Bendire. A 
specimen in Mr. Brewster’s collection taken at Haywards, Cali- 
fornia, February 23, one from Laredo, Texas, January, and a 
young from Big Bend of the Musselshell River, Montana, August 
25, in the U. S. Nat. Mus., are intermediate. Specimen of saya 
from Lower California and Arizona are the palest, those from 
Colorado — the type locality — the most-scorched. 
Yukonensis in juvenal plumage differs from saya in that plumage 
even more than do the adults; the rusty suffusion of the upper 
parts, particularly pronounced on the lower back and rump of 
the latter, being hardly perceptible in the former, and the throat 
and chest of ywkonensis being much darker.
