ng entirely absent on the
outside of the thigh.

"It is, however, worthy of note that those squirrels which have a
rufous tinge in the inguinal region rarely, if ever, have the outside
of the thigh bright red, and that the squirrels distinguished by
white on their thighs are from Bhutan, Assam, and the Garo hills.
But I do not see that these latter differ in any other respect from
the squirrels sent by Hodgson as specimens of _S. lokroides_, with
and without red thighs. Moreover, one of Hodgson's specimens of _S.
lokroides_ shows a tendency in the thigh to become white" ('Anat.
and Zool. Researches,' pp. 247, 248).

The difficulty in laying down precise rules for colouring is here
evident, but in general I may say that the upper parts are rufescent
olive brown, the hair being grizzled or banded black and yellow,
commencing with greyish-black at the base, then yellow, black,
yellow with a dark brown or black tip; the lower parts are rufous
hoary or grey, tinged with rufous, or the latter shade may be
restricted to the groin or inguinal parts. The fur is coarser and
more broadly ringed than in _S. lokriah_, and the ventral surface
is never tinged with orange, as in that species; the tail is
concolorous with the back; the hair more coarsely annulated; there
is no white tuft behind the ears, as in the last species.

SIZE.--About the same as the last, or Dr. Anderson says: "In the form
referable to _S. Blythii_, a white spot occurs on the inguinal region
of the thigh in the position in which the rufous of the so-called
red-legged squirrels is developed. The groin in some of these
squirrels shows also a decided rufous tinge, while the remainder of
the belly is sullied grey white. If these forms were without the white
thigh-spot, they would exactly conform to the type of _S. Assamensis_.
A squirrel in the British Museum, labelled _S. Tytleri_ (Verreau,
'Indes Orientales'), agrees with _S. Blythii_" ('A. and Z. Res.',
p. 249).

Blyth has seen a squirrel of this species renewing its coat, and
assuming a variegated appearance during its transition to the
breeding dress.

A jet-black squirrel of the same proportion occurs in Sylhet and
Cachar, which Dr. Anderson is inclined to think belongs also to this
species.

We may, therefore, regard the following as being the same as _S.
lokroides_, viz., _S. Assamensis_, _S. Blythii_, _S. similis_, and
the black one, which has apparently not been named.

Jerdon states that these
