extent than prevails in S. entellm, is much longer than in th a t species, and the
depth of the face from the distal extremity of the nasals to the alveolar border is
much greater. The premaxUlaries also-are more anteriorly rounded and produced
than in S. entellm, thus conferring greater length on the muzzle. Associated with
the shorter muzzle of S. entellm and its more downwardly compressed face is a
considerable concavity immediately below the orbit, at the base of the muzzle,
external to the maxillo-malar suture, but little marked in S. schistaeem. The
transverse breadth of the face is proportionally greater than in S. sehistaceus,
which is also true of the zygomatic breadth, so that the head of S, entellm is more
rounded than in the mountain species. The palate of S. sehistaceus is relatively
n a r r o w e r and deeper, and its alveolar borders are more parallel. The teeth of S'.
sehistaceus are somewhat larger than in A. enlellus, and the palate, therefore, is
somewhat longer. The petrous bones, also, are not so prominent in the former
as in the latter. The symphysis of the lower jaw is considerably longer and
broader than in S. entellm, and the lower jaw itself is generally more massive
and deep.

The animal is brownish grey on the body, and more or less yellowish on the
h e ad : the anterior extremities are tawny grey and the hind limbs sullied white,
the tail is greyish or brownish, and the under parts of the body axe whitish.
The face is black, the hair on the head towards the occiput -is raised into a kind
of short tuft, which is prolonged backwards to near the nape as a small median
crest, hut it is possible that this may he artificially produced.

This species, the types of which I have examined in Paris, has all the
characters of the entelloid group of Senmopitheei, and notwithstanding its wide
separation geographically from the race of S. enlellus which has been designated
S. priamus and afterwards S. paUipes hy Blyth, it is most closely allied to it,—so
much so th a t Gray has regarded the latter as synonymous with S. albipes, but
Is. Geoff. St.-Hilaire has distinctly stated that this species is peculiar to Manilla.
In its rudimentary crest he saw in it an affinity to the crested Malayan species,
but I agree with A. M.-Edwaxds that Is. Geoff. St.-Hilaire attaohed too much
importance to the radiation of the hair on the vertex. Had it not been
distinctly stated that S. albipes is an inhabitant of Manilla, I should have followed
Hr. Gray’s example and regarded the two as identical.

Pale ashy grey on the upper parts, darkest on the back. The sides of the head,
nape, lower half of the thigh, and the hands and feet yellowish. The outside of
the fore-limb and the remainder of the thigh are pale ashy like the trunk. The
under parts and the inside of the limbs are yellowish. The tail is concolorous
with the hack, but paler towards its somewhat tufted extremity. The face, ears,
and under surface of the feet black.
Such are the characters of specimens from the Coromandel Coast.
Those from Ceylon are much darker, being of a pale vinaceous brown on the
upper parts, except on the sides and front of the head, and on the nape and back
of thighs which are yellowish. The vertex, the outside of the limbs, and the
tail are also vinaceous brown. The under parts and the inside of the limbs are
yellowish.
Blyth described S. priamus as having a compressed, high, vertical crest, but as
one of the specimens in the Indian Museum referred by Blyth to S. priamus shows
no sign of a crest, and as Blyth states that this individual did not possess a crest
in life, I removed the skulls of the two types of S. priamus (No. 30 A & B of
Blyth’s Cat. of Mamm.), and in A, which has a short erect crest, I found that
the skin on the vertex had been cut open and cotton-wool introduced between
the skull and the skin, and that where the cotton-wool was, there the crest existed.
In the other specimen, B, the short crest occurred exactly over the point of a
wire which perforated the skull and pressed against the skin. Therefore, until
the crest has been observed in the living animal, I am inclined to believe that
it had been produced in these stuffed specimens by the bad preparation of the
skins in mounting them.
The type of S. thersites was from Ceylon, and does not differ in any essentials
from the Ceylon individual referred by Blyth to S. priamus.
The skull of S. pria/mm in its adult condition is considerably smaller than
that of S. entellm; the vertical depth of its face is relatively less than in that
speoies, while, on the other hand, it is proportionately broader across the orbits.
