Its fronto-nasal depth also is less than in S. entellus, the nasals being short and
broad, and the nasal opening considerably shorter than in that species. A line
drawn through the centre of the face, from the alveolar border of the premaxillaries
to the supraorbital ridge, does not touch the distal ends of the nasals, these bones
being rather flattened and broad and slightly concave. These differences in the
details of the configuration must confer on S. priamm a very different visage
from th a t of S. entellus. There is not much difference in the teeth of the two
forms, but in S. priamm they are relatively larger than in S. entellus, except the
canines, which are smaller. The palate has the general characters of that of
S. entellus, and, like it, is of variable depth. The differences in the relative sizes of
these two skulls are indioated in the following measurements ■

' Prom the foregoing measurements it will be observed that the lower jaw of
S. seMstaeem is characterised by great depth and breadth of symphysis, and that
S priamus resembles it in having a symphysis relatively broader than S. entellus.
This species inhabits the Eastern Gh&ts of India, and Northern Ceylon.

Brown from the shoulders to the root of the tail, darkest on the middle of the
back paler on tbe sides and tbe posterior half of the outside of the thighs. Anti-
brachium front of the thighs and lower half of leg black, and light brownish on the
front of the tibia; hands and feet black. Head, throat, under parts, and mmde
of brachium and thighs yellow, and especially bright on the chest and belly. Tail
black, brownish towards its tip. Hair of head semi-erect and backwardly directed.
A few black hairs before the ears, which, like the face and under surface of hands
and feet, are black.
The skull of S. hypoleucm has the general features of S. priamm, but it is
smaller and characterised by much less prominent supraorbital ridges, and by considerably
less interorbital breadth, with narrow, rather compressed nasals, in this
respect conforming to the female of S. priamm. A mature male skull taken from
the type of Blyth’s S. hypoleucm resembles in its size and frontal ridges an
adolescent male of S. priamm, cutting its permanent canines and last molar ;
the teeth of this example of S. priamm being considerably larger than those
of S. hypoleucus. The skull of the type is entire, with the exception of the occipital
and basi-occipital portion, and its length from the premaxillaries to the lambdoidal
ridge is 4-26 ; the palate measures T73. The fronto-malar and greatest
zygomatic breadth are respectively 2-55 and 3-30. These measurements show that
this is the smallest of all these species. The lower jaw has a similar symphysis
to S. priamm, only a little narrower, and the coronoid process has much the
same proportion.
This species inhabits the forests of the Malabar Goast, and does not extend
to Ceylon.
