NO. 1271. RE \ 'IE W OF THE HORNED LA RKS—OBERHOLSER. 817 
This form i.s one of the best marked of all the races of Otocorls 
(ilpedri.s^ ditfei'iiig- from the typical subspecies in its very much paler 
upper surface, more pinkish nape, upper tail-coverts and bend of wing, 
as well as in the pure white of throat and eyebrow. Comparisons 
with other forms are elsewhere made, so need not be repeated here. 
This is the race to which, through misapprehension of the identity 
of Dr. (Joues' type, the name Jeueolaeina has, by common consent, been 
applied. Examination of the rediscovered type, however, proves it 
to belong to another race, as fully explained under its proper heading, 
and leaves the present subspecies without a name. So far as definite data 
are concerned, the Ijreeding range of arctlcola must be restricted to 
Alaska and the valley of the Yukon River. How far south it extends, 
or where it intergrades with niei'rlUl does not appear from the speci- 
mens at hand. It remains in oven southern British Columbia until 
into May, and a male from Sumas Prairie, British Columbia, possibly 
represents the form breeding in the mountains not far to the north- 
w^ard of the valley of the Fraser River. 
In autumn and winter arcticola occurs in the northern United 
States, principally west of the Rocky Mountains, there taking to a 
great extent the place of the more eastern hoytl. No specimens have 
been examined from farther east than Fort Shaw, Montana; and the 
southernmost records are Fort Klamath, Oregon, and Salt Lake City, 
Utah. 
This form is usually without yellow anywhere, though in winter 
there is not infrequently a faint wash of this color on the throat. 
The breeding specimens available are quite uniform, with the excep- 
tion of a male from St. Michael, Alaska, which is noticeably more 
reddish on the upper parts. Even in winter there seems to be less 
individual variation than exists in many of the other subspecies. 
Of this race 38 specimens have been examined, representing the 
following localities: 
.lA^sZv/. — Fort Yukon;* St. Michael.*

Root Valley.
