PAPIO ANUBIS.

is no well-defined mantle as in P. hamadryas, the hair on the hind-quarters never having 
the shorn character of that species. The hair on the inner side of the thighs is greyish, 
but on the under surface of the body in the adult male it is banded in the same way as 
the upper surface ; on the thighs the basal dark colour becomes very pale and the 
black mottling is due to the terminal black tips. The face in the stuffed type is black 
and is practically nude on its upper surface, although a very few small hairs may be 
detected here and there, but on the sides of the muzzle they are somewhat more 
plentiful. On the front of the muzzle below the nostrils, along the lips, and on the 
chin there are bristly black hairs. On the area of the ascending ramus of the lower 
jaw, below the zygoma, the short backwardly-directed hairs are nearly white. The 
hands and feet are black, and the black extends up the limbs for a short way. The 
two terminal phalanges of the fingers are nude, with the exception of a few straggling 
long hairs on the upper surface, but the upper surfaces of the toes are thickly clad 
with long hairs. The tail is concolorous with the body, but the hairs on the sides of 
its base are longish, 50 to 60 mm.; the remainder are short, except those at the tip, 
which measure about 70 mm. long, so that it is slightly tufted. The nates are nearly 
black in the stuffed specimen; the hair below them is rather long and dense. The 
muzzle of the male in the stuffed specimen is rather long, and the ridge from the orbit 
to the premaxillaries is well marked. The ears are moderately pointed, nude or semi¬ 
nude externally and internally, but on the latter surface the inner margin of the conch 
is clad, but not densely, with moderately long annulated hairs. An immature female, 
No. 718, from the same locality as the male has all its essential features, but the hair 
on the inner side of the hind legs is greyish, and the hair on the upper surface of the 
hind feet instead of being black is annulated with greyish. 
The leading features of the skull of the male are its broad interorbital septum, the 
breadth of the muzzle at the base below the orbits and anteriorly at its termination, the 
prominent character of the maxillary ridge, and the extent to which the nasal bones rise 
as a central rounded ridge with a slight concavity on each side of them. The palate is 
broad, and the palatal bones in their mesial extent from the spine forwards equal nearly 
one-third of the length of the entire palate. The interval between the palatal foramen 
and the hinder curved border of the palate equals one-fifth of the length of the entire 
palate measured from the anterior osseous border of the posterior nares. 
In this skull the premaxillaries form only a very short suture with the nasal, but in 
the female the suture is considerably broader. 
The skull of the female is unfortunately much injured in its calvarium. Its 
third upper and lower molars are not yet visible, so that the specimen is that of a 
very young animal. But the bone covering the last molar of the right side of the 
lower jaw has been broken off, thus partially exposing the tooth, which is seen to 
have a well-defined third inner cusp, as in the adult female of P. doguera, but it
