hue ou these parts, darker and richer in tone than in M. rhesus, and beooming almost
hlaok on the hands. Below the ear and on the sides of the face the hair is long
and more or less annulated, hut of a greyish tint. As in M. rhesus, and the generality
of Macaques, there is a line of hlaok scattered hairs along the supraorbital
ridges and a patch over the orbital angle of the malar. The chin, throat, and chest
and of the fore-limbs are greyish, washed with pale rufous above the wrists,
while the abdomen and inside of the hind-legs are greyish, suffused with pale
orange-red, the fur being silky. The hair on the vertex is not radiated, and
the ear does not appear to be more thickly clad with hair than in M. assamerms.
The skin around the callosities is described by Dr. Gray as crimson, and the
face he characterises as pale flesh-coloured. The area around the callosities is
well clad Dr. Gray also describes a small naked red spot at the outer angle
of each eye, which is occasionally feebly developed in M. rhesus, and which occurs
also in M. leomnrn, Blyth.
A. M.-Edwards, in the Beoh. des Mammifères,1 states th a t he is disposed to
regard M. lasiotis and M. tcheliensis as of the same specific type, if the normal
dimensions of the tall are the same in both. In M. tcheliensis the tail only equals
nearly the length of the hind-foot, and is also distinguished from the tail of
3f. rhesus by being clothed with thick long hair. The skull of M. tcheltensts,
which I have examined, so agrees with the skull of M. lasiotis that, making
due allowance for the difference of sex, there seems to he every probability that
A M-Edwards’ supposition is correct. He desoribes M. tcheliensis as having
the hair thick and rather long, soft, and silky. The general colour is a brilliant
reddish fawn, especially on the hinder parts, becoming greyish on the
shoulders and on the sides of the cheeks, where the yellow is lost. The hands
and feet are greyish fawn, the under parts are almost grey, and the tail is con-
colorons with the hack.
I t will be observed that A. M.-Edwards makes no mention of the ears of
M tcheliensis, hut these organs in M. lasiotis have been described by Dr. Gray
as ovate, prominent, exposed, and covered with hair. T h e s e characters, however,
cannot now be detected in the dried skin, any more than they can he in the type of
M. tcheliensis. «.
The skull of M. lasiotis (figs. 9 and 10) is distinguished from the skull of
M. rhesus by its more massive character, greater rotundity, shorter, deeper, and
more vertical muzzle, and greater facial breadth. The frontal area lying behind the
supraorbital ridges is much more expanded than in Ai. rhesus, n d f c occipital
region is broader. A comparison of the measurement of the skull of the male
M. rhesus (fff. oinops) which I have given under M. assamemis with.the measurements
in the following table proves th a t there is very little relative difference
between the dimensions of the two skulls, while the accompanying woodcut will
i L . c., pp. 227-229,
show clearly wherein they differ. The principal difference lies in the much greater
transverse breadth of the base of the skull of M. lasiotis, which is 3 inches to

of the latter 5*23, the two then being of nearly equal length. But the circum
