This well-marked species approaches S. erythrieus in size. The lower parts
and inside of the limbs are deep ruddy ferruginous ; the head, sides of neok, shoulder,
outside of fore limb, thigh and outside of hind limb, being minutely speckled
with white on a blackish ground ; feet black, the rest of the upper parts of the body
with the base of the tail yellowish-rnfous, punctulated with yellow and black ; tail
bushy and black ; whiskers blaok. The specimen in the British Museum referred by
Dr. Gray to S. rufogaster var. iorneoensis, differs from Malayan specimens in having
portions of the upper parts unannulated and of deep rich chestnut, whioh embraces
the upper surface of the base of the tail and is ooncolorous 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-brown, extending along
the dorsum of the tail for about three inches.
Müller and Schlegel mention a variety that I have not seen, and of which they
state that the red colour of thè under parts extends to the heel, the fore foot and
the toes, while the colour of the upper parts passes into a uniform, lustrous black.
They also remark, however, that the hack not unfrequently assumes a pale yellowish-
brown tint.
In the skull the orbit is rather large, and the muzzle is so contracted at its base
that the extremity is hut little narrower.
This species was stated by Is. Geoffioy to have been described from a speoimen
obtained in Java by Diard, and this type I have examined. I t also occurs in the
Malayan peninsula and Sumatra, but Schlegel and Müller likewise record it from
Canton. #
The squirrel observed in Assam by M'Clelland, and referred by him to this
species, was another allied form, 8. erythrceus. Blyth was inclined .to regard
the S. castaneoventris, Gray, as the young of S. hvpput'us, but in this he was
mistaken, as the two are quite distinct.

This species equals 8. gordoni in size, to which it is closely related, but from
which, as far as our present knowledge goes, it is distinguished by its orange-red head
and feet, and by the bright brick-red tip to its tail; the colour of its under parts is
the same as in S. gordoni, and they are concolorous with the head and feet. No
ventral, grizzled line. The upper parts are grizzled rufous-olive and the annulation is
fine, and the fur of moderate length; the forehead, face, chin, throat, belly, and inside
of limbs, front of thighs, lower half of fore limbs, and the head and feet, are rich
orange-red. The tail is rather bushy, as long as the body without the neck and
head; it is concolorous with the upper surface of the body, but slightly more rufous,
with a bright chestnut-red tip.

I obtained this species at Thigyain in Upper Burma.
The skull of S. sladeni has a rather short muzzle with considerable breadth
across its base superiorly, and it is a shorter and broader skull than the s k u l l s of
squirrels referred to S. blcmfordii. Compared with the skull of the red-headed
specimen of S. erythrceus from Bhutan, there is a decided resemblance between
the two, the chief distinction being the less breadth of the base of the muzzle
of the latter; but the teeth of this specimen show it to be young, while the teeth
of S. sladeni are much worn by use.

The following squirrels which have been described from Burma and Siam and
from some of the small islands which lie off the latter country, appear to me to be
only varieties of one and the same species. They are S, Jmlaysoni, 8, ferrugineus,
