Brewster on Kennicotf s Owl and some of its Allies . 29 
margined with black. Secondaries and inner webs of primaries crossed by 
from six to seven bars of pale reddish-brown. Outer webs of primaries 
with broad, quadrate spots of brownish-white. Tail regularly but faintly 
barred with light reddish-brown. Feathers of the sides of head and neck 
thickly but minutely mottled with dusky upon a lighter ground. Lores 
nearly pure white. A somewhat broken facial-circle of black or chestnut 
spots and blotches. Beneath ashy-white, lightest on the abdomen, with 
numerous fine, regular, transverse bars of black and coarse shaft-stripes 
of the same color; the only immaculate space being that along the middle 
of the abdomen. Lining of wings and concealed silky plumage of sides 
under the wings, pale ochraceous. Tarsi, dull chestnut. Wing, 7.10; cul- 
men, .61; tarsus, 1.77; tail, 4.10; middle toe, .75; ear-tufts, 1.45. 
The above description is of a specimen representing the extreme 
grayish phase so far as shown by the series before me. Six oth- 
ers from the same locality vary a good deal in color and mark- 
ings, some of them being very dark with coarse shaft-stripes, 
both above and below, while one or two have the dorsal surface 
nearly like that of asio in its corresponding condition. In all, 
however, the plumage of the under parts is somewhat different 
from that of asio , the transverse bars being usually much finer 
and more regular and the ground color ashy instead of clear white. 
These differences seem to be most strongly marked in the purely 
gray specimens which otherwise afford the nearest approaches to 
asio. 
Among the darker birds are three which may be considered as 
about intermediate between the extreme brown and gray phases. 
The first, from Mr. Henshaw’s collection (Fort Walla Walla, 
Nov. 7, 1880, Capt. Bendire) has the dorsal plumage dark brown 
with an umber cast, while the tibise, lining of wings, outer webs 
of scapulars, and numerous pairs of rounded spots forming a 
band or collar across the nape, are tawny-ochraceous of nearly 
as deep a shade as in typical brown birds. The dark shaft- 
stripes in this specimen are broader and blacker than in any of the 
others and the usual ashy cast beneath is replaced by an ochra- 
ceous one. The remaining two birds are similarly characterized 
but to a less marked degree. All three combine the gray and 
brown coloring of the respective extreme phases, precisely as do 
many of the eastern specimens before me, the gray and red condi- 
tions of S. asio. 
The Portland specimen already mentioned, although in some 
respects an intermediate, is on the whole nearer the gray than
