The skull of this remarkable animal is distinguished from the skulls of the
other Semnopitheci, by its highly arched, but rather narrow, retreating forehead;
by the great breadth of its orbits, the little marked prominence or arching of the
interorbital space compared with that of the other crested species in which it is
narrower than in S. frontatus ,* by its broad but short and truncated facial portion;
and by the more retreating character and less depth of the symphysis of the
lower jaw. ,
■ This species is a t once recognised by the bare, milky-coloured, nude area on its
forehead, by its remarkable, blunt-shaped crest, and by the long dependent tufts
from the forehead and sides of the face.
Inhabits Borneo.

Upper surface of the body and sides greyish, passing into blackish on the forehead,
and into black on the base of the neck, front of the breast, shoulder, brachium,
thighs, hands and fe e t; the anti-brachium white, and the lower half of the hind
limb red or reddish brown. A large area on the rump immediately above the tail
involving its base and passing round to the groin, white, all the tail being similarly
coloured. Head brown, with a narrow band of chestnut passing under the ears
backwards, and a broader band of the same colour, margined with black, posteriorly
passing over the chest from shoulder to shoulder; the whiskers long, white, and
directed backwards. The face naked and lemon-coloured; the callosities, palms, and
soles yellow. The hairs of the trunk are annulated with from 10 to 12 rings of
white and blackish.

Both sexes in this beautiful monkey, and in its near ally, S. nigripes, are alike
in colour, and the young differ but little from the adult.
The skull has the forehead rather low and the interorbital space rather broad.
The facial portion is broad at the base, but rounded anteriorly.
As is now well known, this animal presents all the structural features of
Semnopithecus.
Inhabits the northern portion of Cochin China. The naturalists of the
* Bonite ’ encountered it in numerous troops near Tourane.

In S. nigripes the posterior extremities are uniformly blackish from the origin
of the tail downwards, while in S. nemaeus the lower half of the limb is brown.
The anterior limbs are greyish black, uniformly speckled with white, whereas in
S. nemaeus the anti-brachium is white. The same general distribution of colour
prevails as in the last-mentioned species. The face is nude and appears to be
yellow as in the douc, and there is a frontal band of black hairs directed a little
forwards, but which, however, in S. nemaeus is less intense and more backwardly
recumbent. I t also resembles the douc in having the base of the neck and front
of the breast surrounded by a black collar which is bordered with red, b u t the
whiskers of S. nigripes are black and shorter.
The back, the flanks, and the belly are covered with clear brilliant grey hairs,
tending to fawn, and finely annulated with deep grey, often black. The precaudal
area is pure white, and contracts towards the tail, which is entirely white and very
long.
The proportions between the skeleton of S. nigripes and S. nemaeus appear to
be very different, the limbs of the former being more elongated than those of the
latter. The skull is relatively much smaller and the brain-case is more depressed and
