We must take it that R. pyrsonota differs from the latter not so 
much in the colour of the feet as in the markedly annulated and 
ochraceous upper surface. 
According to Mr. Bonhote, who last reviewed the squirrels of 
the Prevostii group (A. and M. N. H., 7, vii, 1901, p. 169), we have 
only two forms inhabiting the Peninsula: Sciwrus prevostii typicus, 
in which the lateral white stripe runs unbroken from top of 
nose to heel of hind foot (extending also down the outer side of the 
fore limb), and S. p. hume7, which has the shoulders fulvous-red, the 
colour of the fore limb extending upwards until it meets the black of the 
back. iS. p. typieus appears to be confined to the southern extremity 
of the Peninsula ranging to Malacca, with perhaps Negri Sembilan, 
and the southern half of Pahang: I have examined Pahang examples 
from Tras, Liang and from the lower course of the Pabang River 
(Lebeh Tua). Examples of S. p. humei, Bonh., are known to me 
from Southern Perak (Blanja and Sunekai) and from localities through- 
out Selangor. 
Two individuals of this group from Lipis and others from elsewhere 
fit with neither of these descriptions. From the first, they differ in 
having a variable degree of fulvous wash on the shoulders, and from 
the scoot in that the colouring of the shoulders is never so intense or 
so large in extent. Their area ic distribution seems to surround the 
red-shouldered form on the north and east, and I propose that in- 
dividuals of this appearance should be known as :

Typr.—Adult male (skin and skull), No. 1,330/10, Selangor Museum. 
Collected at ae Kuala Lipis, Pahang, llth May, 1910, by 
C. Boden Kloss. Original No. 3,261. 
CuaractEers.—-Resembles Sciuwrus prevostii, Desm., but has the 
shoulders washed with the fulvous colour of the fore legs: differs from 
S. p. humei, Bonhote, in that the colouring of the cHouldevs is much 
less intense and frequently falls short of the black of the back. 
Cotour.—Above deep shining black. Below, including the entire 
fore limbs to elbows and the hind feet, a rich fulvous, deepest on the 
abdomen. On either side from back of shoulders to heel of hind feet 
a creamy white stripe broadening on the outer sides of the thighs. 
The fulvous hairs of the abdomen between shoulder and thigh adjoin- 
ing this stripe have black bases. Sides of muzzle, chin, cheeks and 
sides of neck running up behind the ears chalky-white somewhat 
evizzled, the region below the eyes being darkest. Shoulders pale 
fulvous white, gradually deepening into tke colour of the fore legs. 
Tail blackish below and grizzled at base, bleaching on the upper 
surface to a deep brown with a pale tip. 
SkuLy anp Tretu.—Skull and teeth do not in any way differ from 
those of the related forms,
