deep black. There are no parietal whorls; but the hair on the head is long and
directed baokwards, and originates in a peak as far down as the glabella, and is
smoothed down on the top of the head from the occipital crest backwards, and is
whitish with a yellowish tint. On the back of the neek and between the shoulders
the colour tends to ashy hrown, and thereat of the body posteriorly is somewhat
paler than the sides. The tail is ooncolorous with the hind part of the back and
much longer than the body, but not tufted. The under parts and inside of the
limbs and outside of the thighs are of a slightly paler tin t than the upper parts.
The mouth and eyelids are whitish, but the rest of the face is black. The newly-
born young is bright fulvous, but the fur soon changes, and in specimens with the
body 11-80 inches in length, the fur is dark ashy brown, very faintly paler on the top
of the head, which tends to grey. The hairahove the orbits and pn the sides of
the cheeks is hlaok, which is also the colour of the hands and feet. The rufous
colour of the voung is most slow to disappear from the head, throat, flanks, thighs,
and the terminal half of the tafl. Length of the adult male hody 1 foot 9 inches,
tail 2 feet 8 inches. Although there is a somewhat strong resemblance between the
colouring of this species, exeluding the pale hairs on the head, and that of S. namenm
which is associated with it in Malacca, as is proved by Cantor’s catalogue and specimens,
yet the S. namenm (S. altocmerem, Cantor), in the presence of its crest is
more Closely allied to S. mitratue, of which it appears to he the continental representative.
S. obscwme, on the other hand, presents some general characters which
affine it to the somewhat similarly coloured species on the opposite side of the Bay
of Bengal, viz., S. johnii. # . , ,
The skull of S. obscurus is distinguished from that ot S. siamenm by the
narrower character of its face, the less outward projection of the external orbital
process of the frontal, and by its less capacious orbits. The frontal region also is
much narrower than th a t of S. smmensis, in, which the area between the temporal
ridges is broad and expanded, whereas it is much more limited in this species. The
orbital septum anteriorly is longer and broader than in S. « a— I t differ,
also from the skull of true S. maurus, by the greater flattening and expansion of
the occipital region and .the longer and less obtuse character of the bram-case
and the greater breadth of its base. , . , B H I
This species occurs in Siam and the Malayan peninsula, and is n o t ^ f r e quently
offered for sale in the Singapore market. I have examined H B |
S. obscurus, S. lemeomytax, and S. halonifer, all of which m no way differ from one
“ 0 tc Intor has doubtfully referred the Simia mama, Baffles, to this species, and
explains the Circumstance that Baffles described the face as black on the gm H
th a t he had never seen S. maura alive; but the typical example m
Museum, London, is a monkey in no way resembling this species and constitutes the
type of S. femoralis, Horsfield, a specimen of which from Cantor exists in the
same Museum, and is in no way separable from S. sumatranm, Muller and
Schlegel.
S e m n o p it h e c u s h o l o t e p h r e u s , n . s .
Uniform dark slaty gray passing into black on the fore-arm and hands, and also
on the feet. Under parts and inside of front limb and thighs pale-yellowish grey.
Head slightly crested over vertex, but only with a feeble tendency to lateral
compression. Supraorbital hairs moderately long and black. Whiskers rather
long, directed backwards and outwards, hiding the ears in front. Eace bluish black;
area around the eyes and the lips white.
The nasal region of tbe skull is rather prominent, nearly straight, and
moderately broad, with the orifice narrow and rather long. Supraorbital ridges
are well developed, and the orbits are nearly round and of moderate size. The
premaxillaries form a slightly expanded suture with the nasals. The last-mentioned
bones are about half the lateral length of the premaxillaries. The palate
has moderately broad margins, very slightly posteriorly convergent.

The pelage of the types of this species is pale silvery grey on a darkish background
which passes into deep black on the hands and feet. There is a strong
supraorbital line of black hairs which, however, project outwards and backwards,
and the cheeks are covered with long grey hairs. The hairs on the flanks are long,
silky and grey. The under parts are greyish. The tail is longer than the body
and grey. The young is bright orange-yellow, except on the top of the head, the
antibrachium and feet, which are blackish. The colour of the face in life is not
known.
Habitat.—Cochin China.
