280 MAMMALIA OF INDIA. 
No. 277. ScIURUS LOKRIAH. 
The Orange-bellied Grey Squirrel (Jerdon’s No. 153). 
Native Names.—Zckriah, Nepalese ; Zhamo, Bhotia, Kidd, or Kaldi- 
tingdong, Lepcha (/Jerdon). 
Hapirat. — Nepal, Sikim, Assam (Khasia Hills), and Burmah 
(Arakan). 
DESCRIPTION.—A deep ferruginous olive-brown, the hairs tipped with 
orange, soft and silky; the under-parts from chin to vent and the 
outside of the thighs a rich orange ; the tail is shorter than that of the 
next species, concolorous with the body above, but the banding of the 
hair is coarser, the apical black band being very broad, tipped with 
orange or white, generally the latter, the general hue being blackish 
washed with orange or white. In some the general hue is orange brown 
with obscure annuli; the arrangement of the hair is distichous or in 
two rows. 
S1zz,—Head and body, about 8 inches ; tail, 64 to 8 inches, including 
hair. 
There is some confusion between this and the next species, S. Zokroides, 
and the distinctive characteristics quoted by Jerdon and others, founded 
on colouring alone, are not to be depended upon, for colouring varies, 
but there is considerable difference in the skulls of the two, S. Zokriah 
having a smaller skull, with distinct peculiarities. The inter-orbital 
portion of the skull is narrower anteriorly and posteriorly, and the muzzle 
is narrow at the base, and of nearly equal breadth throughout. The 
nasals are long and narrow, and reach further back than in S. lokroides. 
These points, which are brought forward by Dr. Anderson, are sufficient 
to indicate that they are quite distinct species. As regards colouring 
S. lokriah has normally red thighs, but even this is absent at times. 
Dr. Anderson says: ‘“ Itis much more-richly coloured than SS. lokroides, 
with no rufous even on the thighs, and with generally a tuft of pure 
white hair behind the ear, by which it can be recognised, as it occurs 
in twenty instances out of twenty-five, and even when absent the hairs 
in that locality have a paler colour. As this whitish tuft lies backwards, 
it is only seen when the ear is carefully examined.” 
No. 278. ScIURUS LOKROIDES. 
The Hoary-bellied Grey Squirrel ( Jerdon's No. 154). 
Hapitat.—In the lower ranges of the South-eastern Himalayas, 
Nepal, Sikim, Assam, Tipperah and Arakan. 
DESCRIPTION.—This is a most difficult species to describe. Dr. 
Anderson writes: ‘‘I have before me sixty-two examples of various
