Sciurus Prevostit Hume, subsp. n. 
Sciurus Prevostii, Desm., Thos. P. Z. 5. 1886, p. 76. 
Differs from the preceding form in the red of the under- 
parts covering the whole of the fore limbs and spreading 
upwards over the shoulders till it meets the black of the back. 
The cheeks are grizzled, but behind and below the ear is a 
pure white patch. The hind feet are of a morc brilliant and 
purer chestnut than in S. P. typicus, and the black sublateral 
stripe is not always present. 
Dimensions similar to the last.

Sciurus Prevostit sarawakensis, Gray. 
Macroxus sarawakensis, Gray, Ann. & Mag. Nat. Hist. xx. 1867, p. 277. 
This race, of which only two specimens are known, is very 
distinct from the preceding forms. One of the chief features 
(common to this and the next) is the tail, the hairs of which 
have long light fulvous tips, which, though sometimes worn, 
are always to be seen. The black of the back is somewhat 
restricted ; it narrows down to a stripe over the shoulders, and, 
broadening out over the back, narrows again over the thighs 
to astripe about the width of the tail. The lateral stripe, 
which is narrow and of a dirty white between the limbs, 
broadens out to cover the whole of the thighs, where it is of 
a light fulvous, each hair being black at its base. The whole 
of the underparts, shoulders, sides of neck, face, and limbs 
are of a deep chestnut, slightly tinged with fulvous over the 
shoulders, and with a tendency to being grizzled on the cheeks, 
There is no sign of the sublateral black stripe. 
Dimensions as in Se. Prevostit typtcus.

Sciurus Prevostit kuchingensis, subsp. n. 
Very similar to Sciurus Prevostit sarawakensis, but differs 
in the lateral stripe being pure white, in having a much 
Jarger extent of black on the neck and back, and in the ful- 
yous tips to the hairs of the thighs being small, so that the
