k on the Mammals of Thibet, so I will quote
Dr. Anderson's description from the types he examined: "The head,
the sides of the neck, the throat and upper part of the chest,
variegated with white, through which the rich maroon of the ground
colour is partially seen, and it forms a ring around the eye; the
hinder part of the back is yellow, and the tail, immediately beyond
its base, is also yellowish for a short way, fading into the deep
maroon of its latter two-thirds. It has no black tip. The feet are
concolorous with the body; the under parts are pale rich orange
yellow; the ears are large and moderately pointed."--'Anat. and Zool.
Res.,' p. 284.

SIZE.--Head and body, about 23 inches; tail, 16 inches.

NO. 302. PTEROMYS MAGNIFICUS.
_The Red-bellied Flying Squirrel_ (_Jerdon's No. 162_).

NATIVE NAME.--_Biyom_, Lepcha.

HABITAT.--South-eastern Himalayas, Nepal, Sikim, Bhotan; also in
the hill ranges of Assam.

DESCRIPTION.--Upper parts dark chestnut or a rich lustrous dark
maroon chestnut, with a golden yellow mesial line in some; the hairs
are black tipped, the dark portions of the back being finely but
obscurely punctulated with dark orange; the shoulders and thighs are
golden yellow, and the under-parts are orange fawn or orange red;
so is also the margin of the parachute; the ears are large, semi-nude,
sparsely clad with pale red hair externally, and bright red
posteriorly, the base of the upper surface being clad with long hair;
the sides of the face below the eyes are yellowish; there is a black
zone round the eyes; the chin and the feet are blackish; the tail
is orange red, tipped more or less broadly with black.

SIZE.--Head and body, about 16 inches; tail, 22 inches.

The young of this species have not the dorsal line, the head and neck
are concolorous with the body, as is also the tail at its base; the
under parts are pale yellowish-red. According to Dr. Anderson the
skulls of _Pteromys magnificus_ and _P. oral_ differ in the shorter
muzzle and the more elevated character of the inter-orbital
depression of the latter. This animal is occasionally found at
Darjeeling, and according to Jerdon it used to be more common there
before the station was so denuded of its fine trees. It frequents
the zone from 6000 to 9000 feet, and feeds on acorns, chestnuts and
other hard fruit; also on young leaves and shoots. There is a coloured
plate of this species in the 'Journal of the Asiatic Society of
Bengal,' vol
