Two skins from Aver Kring, Negri Sembilan, on the
eastern watershed of the Peninsula (Nos. 239, 240/12) are
typical, but a third has the speckled markings on the feet well
developed, while there is a tendency to the same change on
the hands. (No. 241/121.
But of seven skins from Triang, about 20 miles north from
Ayer Kring, three, Nos. 475. 477, 480/12 are typical, though the
feet are somewhat paler chestnut, while the others showmarked
variations.
One No. 479/12 has the hands and feet almost entirely
white, the colour of the hands soiled with chestnut and the
feet with a narrow ring of chestnut near the ankle. The bases
of the hairs throughout black.
Another, No. 478/12 has the hands dull chestnut, intermixed
with many black and silvery white hairs and the feet
silvery, dark maroon towards the ankle. The point of the
shoulder blackish and the shoulder above much sprinkled with
blackish hairs so that the white lateral stripe appears partially
interrupted. No. 476/12 is more nearly normal but has the
feet decidedly paler chestnut and the feet dirty whitish on the
distal phalanges, chestnut on the proximal. No. 481/12 differs
in the greater extension of white down the forearm towards
the fingers, which are orange, and in the paler tint of the feet,
which are clad with buffy golden hairs towards their
extremities.
These variations all occurring in specimens from one
localitv and which are not correlated apparently either with
the age of the individual or with that of the pelage, which is
fairly fresh and uniform in the whole series, appears to indicate
a state of unstable equilibrium in the species, parallel to
but on a smaller and less striking sc;:l
