the head and nape of neck. At this season the face and sides of the head

brown, gradually passing into the dark brown of the body ; nctfdistinct
dorsal streak ; caudal disk very large and pure white, with a narrow dark
line crossing it to join, the dark tail ; a darker streak on the flanks, below
which the under-parts are pure white and sharply defined from the dark
area ; front and part of sides of legs very dark blackish-brown, and the
remainder white.
This race is typified by an adult mounted male from the Liard river in
the British Museum, partially described by Col. J. Biddulph on pp. 679
and 680 of the Proceedings of the Zoological Society for 1885. It is in the
winter pelage, and appears to be nearly allied to the north-western race,
but is as Targe as the typical representative of the species. Unfortunately
the north-western race is described from specimens believed to be in the
Summer pelage, and it is therefore by no means- improbable that in winter
they might develop a similar mane, and display equal lightness in the
colour of the face, as compared with that o f the body. Even, however, if
such were the case, the present form would apparently be differentiated by
its larger size, and.since it inhabits an area lying between that of typica and
stonei, it may at least provisionally be allowed to rank as a separate race.
Distribution.—Typically the neighbourhood of Liard river, near the
northern extremityiljf the Rjflky Mountains/ in about latitude 590 N.

Character.i^^HTie original description of the adult male, apparently in
thejiummer pelage, runs . as follows Above gray, formed by an
intimate mixture of whitish and blackish-brown ; face, ears, and sides of
neck lighter and more whitish, being much less varied with blackish-
brown ; whole posterior area and lower-parts from hinder part of back
downward and forward, including the posterior aspect of thighHand the
abdomen,, white, the white area narrowing anteriorly and terminating in
a V-shaped point on the middle of the chest ; also a broad sharply-defined
band of white |j|n the posterior surface of both fore- and hind-limbs,
extending from the body to the hoofs, and above including also the inner
surface; front-'iSf neck, from base o f lower jaw posteriorly to, the white
