lorous with the back from the basal
third, then gradually less grizzled; the terminal half black;
whiskers black. Pallas describes the black of the tail as passing
upwards in a mesial line.

SIZE.--Head and body, about 9 to 10 inches; tail with hair, from 11
to 12 inches.

NO. 285. SCIURUS GORDONI.
_Gordon's Squirrel_.

HABITAT.--Upper Burmah.

DESCRIPTION.--Dr. Anderson, who first named this species, describes
it as follows: "_S. Gordoni_ has the upper surface and a narrow line
from between the fore-limbs along the middle of the body grizzled
olive-brown or greyish, with a variable rufous tint; the annulations
are not so fine as in _S. erythraeus_. The chin and sides of the throat
are paler grizzled than on the back and the lower part of the throat;
the chest, belly, and inside of the limbs are either pale yellow or
rich orange-yellow, or passing into pale chestnut in the Assam
variety, in which the belly is rarely lineated. The ears are feebly
pencilled; the tail has the same proportion as in _S. erythraeus_
and _S. castaneoventris_[20] but it is more persistently and
uniformly concolorous with the body than in these species, and is
finely ringed with black and yellow, the rings being most distinct
on the latter fourth; the tip is generally washed with orange yellow"
('Anat. and Zool. Res.').

Hainau.--R. A. S.]

SIZE.--Head and body, 9 inches; tail, 7 inches.

NO. 286. SCIURUS HIPPURUS.
_The Chestnut-bellied Assam Squirrel_.

HABITAT.--Assam; also in the Malayan peninsula.

DESCRIPTION.--Upper parts of the body, with base of tail
yellowish-rufous, punctulated with yellow and black; the lower parts
deep ruddy ferruginous or chestnut; feet, tail (which is bushy) and
whiskers black.

Dr. Anderson, however, mentions several varieties. He writes: "The
specimen in the British Museum referred by Dr. Gray to _S.
rufogaster_, var. _Borneoensis_ differs from Malayan specimens in
having portions of the upper parts unannulated and of a deep rich
chestnut, which embraces the upper surface of the base of the tail,
and is concolorous with the chestnut of the under parts. This,
however, is evidently not a persistent form, because I have seen a
specimen from the same island in which the red portion of the upper
parts is grizzled and much of the same tint as Malayan individuals,
except in the mesial line of the neck and back, where the colour is
rich red-
