northern bird are rather brilliantly ruddy are of more restricted size
and of a dull tone, and there is extension of black and grayish areas.
It seems likely that these two birds represent two different subspecies.

There are no adult females of Lagopus runestris dixont available,
and but two summer males (nos. 371, 372, Port Frederick, Chichagof
Island, July 30, 1907). Two summer males from Atlin, British
Columbia, loaned by the Provincial Museum, Victoria (no. 2566, June
26, 1914; no. 2589, July 1, 1914), are quite unlike dixoni, sufficiently
so to make it seem improbable that dixonz is a southern race of general
occurrence on the mainland as well as on the Alaskan islands.

The Nine-mile Mountain female possesses one feature worthy of
comment. The six outer tail feathers on each side are white basally,
the total white area covering more than half the tail. On the inner
rectrices the white extends over about the basal three-fourths; it
decreases on the inner web of the outer feathers, though extending far
toward the tip on the outer web (see fig. A). This is exactly the
character ascribed to Lagopus hyperboreas Sundevall, of Spitzbergen
(see Dresser, 1871, p. 179, col. pl. no. 482, text fig.; Ogilvie-Grant,
1893, p. 51). The white tail was not peculiar to the one specimen
collected, for other females were seen on Nine-mile Mountain which
had the same marking. It was conspicuous in flight. No male was
noted with this character; in fact no male rupestris was positively
recognized.

The two chicks collected are readily distinguished from young
lewcurus by their generally browner color. Young leucurus is dis-
tinetly gray. The young of /agopus is more ruddy throughout.

Lagopus leucurus leucurus (Swainson). White-tailed Ptarmigan

Found only on the eastern ridge of Nine-mile Mountain. Four
specimens collected, two adult females and two chicks (nos. 42036—
42039). The young birds, taken on July 26 and August 1, respec-
tively, have some natal down about the head; otherwise they are in
juvenal plumage. Three broods of white-tailed ptarmigan were seen,
one of two chicks, one of three, and one of twelve.

Circus hudsonius (Linnaeus). Marsh Hawk

An adult male was seen repeatedly during parts of June and July
about the same locality in Kispiox Valley. At the end of the summer
the first migrant was seen September 10, and a few others were noted
at later dates.
