General colour of the body pale yellow, washed with ashy grey or brownish on
the nape and back, and with a darker tint of the same colour on the shoulders
and the outside of the limbs. A strong line of black supraorbital hairs, as in
all its Indian allies: no crest. Hands and feet and their under surfaces and the
skin of the face and ears black. The tail is concolorous with the back, but paling
towards its tip : it is about one-fourth longer than the body.
This form is most nearly allied to 8. schistaceus, but I have observed individuals
which in their bright colours approached closely to the allied form occurring
in Assam, viz. S. pileatus. A consideration of the types of 8. schistaceus, S.pileatus,
8. hypoleucus, and S. priamus, in conjunction with a large series of S. entellus, leads
me to believe that in the following synopsis of the group we have the species
arranged according to their affinities. I have examined the entelloid monkeys which
Colonel Sykes obtained in the Deccan, and which I do not consider to differ specifically
from this species. Sir Walter Elliot was inclined to regard the entelloid monkey
from Southern and Central India as belonging to a distinct form which he named
8. anchises, and an example of which in the shape of a skin was sent to Blyth at
Calcutta, who considered it to be S. entellus. Unfortunately this skin no longer
exists in the Indian Museum, and there are no materials at present available for
the settlement of this point; but having every reliance on Blyth’s judgment in such
a matter, I accept his views regarding S. anchises.
The characters of the skull of this species I enumerate under 8. schistaceus.
This species appears to range from the Deccan northwards to the right bank of
the Ganges, but what are the limits of its distribution to the west and north-west is
not accurately known, but it reaches to the seaboard to the east, and in the Himalayas
is replaced by S. schistaceus, to the south-east by S. hypoleucus, and to the
south-west by. S. priamus. In Assam it is represented by S. pileatus.
The food of the entelloid monkey appears to consist very largely of the leaves
of forest trees.

General colour of the upper parts, except the head, dark slaty, darkest on the
outside of the fore-limbs; dark on the thighs, but paling towards the an k le ; hands
and feet concolorous with the limbs. Head pale yellow, nearly white; chin,
throat, chest, and under parts and inside of limbs yellowish. The tail is concolorous
with the back, darkening towards its tip. The ears, palms, and soles are black.
The fur long, wavy, and profuse.
In old individuals the general colour is paler, inclining to grey and even to
white on the head, while in the young and adolescents the feet are occasionally
darker than in adults.

The skulls of S. entellus and 8. schistaceus present certain features by which they
can be separated the one from the other, and the differences tha t exist between them
are greater than those which subsist between S. entellus and S. priamus. The skull
of 8. schistaceus is somewhat larger than tha t of S. entellus. The supraorbital!
ridge of 8. schistaceus does not form so thick and wide a pent roof as it does in S.
entellus, and it is less forwardly projected. But the most marked distinction is to
be observed in the much longer facial portion of the skull of S. schistaceus, i.e., in
the interspace existing between the middle of the supraorbital ridge to the extremity
(alveolar) of the premaxillaries, an interval which is considerably longer f.ba.n in
8. entellus. When the skulls of the two forms are placed in natural position, it is
observed that the supraorbital ridges of 8. entellus are projected more anteriorly to
the lower margin of the orbit than in S. schistaceus. This character is brought out
when a line is produced from the middle of the supraorbital ridge to the tip of the
premaxillaries. In S. entellus the line rests against the supraorbital margin, and
may either touch or not touch the distal ends of the nasals and the extremities of
the premaxillaries, thus including two well-marked concavities, one the fronto-nasal
and the other the naso-premaxillary, the latter being the larger and the best
defined of the two concavities. In 8. schistaceus the line does not touch the extremity
of the premaxillaries, but owing to the almost straightforward projection of the
nasals passes a long way anterior to the alveolar margin of the premaxillaries, and
if it were not that the supraorbital ridge is swollen, the line would be almost
wholly in contact with the nasals. This forward projection of these bones gives
rise to a much greater breadth of the maxillae, between the inner border of the orbit
and the nasal portion of the premaxillary, than occurs in 8. entellus. The external
nasal orifice, owing to the forward projection of the facial bones to a much greater
