412 Dr. C. W- Andrews on a new Baboon from 
of the skull preserved is an imperfect right maxilla (fig. 3) 
of a rather younger individual with the true molars in an 
excellent state of preservation. 
The portion of the face beneath the orbits is short and 
considerably deeper than in Papio, Theropithecus, and in the 
female Macacus, the skulls most nearly resembling the fossil 
in this respect being those of males of Macacus and Cerco- 
cebus; this deepening of the face is consequent upon the 
large size of the maxilla, which, again, seems to be correlated 
with the relatively large size of the cheek-teeth. The outer 
face of the maxillais, on the whole, gentiy convex from above 
downwards, there being only a very slight concavity on the 
side of the face in front of the base of the zygomatic arch, as 
in Macacus. In the type-specimen of Papio subhimalayanus, 
Meyer, sp., this depression is likewise wanting, but here the 
depth of the maxillary region is much less. In Papio and 
Theropithecus this depression is well developed, and in the 
males may form a sharply defined fossa. 
The nasals are entirely wanting, but it can be seen that 
they were. small and that possibly the maxille met in 
the middle line above them; it is not possible to be certain 
what were their relations to the facial processes of the 
premaxille, which are the only portions of those bones 
remaining. These processes are short and probably only 
just overlapped the lower ends of the nasals, a condition 
resembling that seen in Theropithecus. In Papio, Macacus, 
and Cercocebus, on the other hand, the posterior ends of 
the premaxillze extend considerably between the nasals and 
maxillze behind the level of the posterior border of the narial 
opening. 
The facial suture between the maxilla and jugal com- 
mences at about the inner third of the lower border of the 
orbits, and runs outwards and downwards on to the base 
of the zygomatic process, the lower edge of which is in part 
formed by the maxilla. he anterior face of the jugal, which 
is relatively large and massive, is gently convex ; it looks 
more directly forwards and less upwards, and stands out 
farther than in Papio or, to a less degree, Macacus, in this 
last respect even surpassing Theropithecus, where also it is 
very prominent. The nearly vertical position of the jugal is 
correlated with the shortness of the face, the backward slope 
being especially marked in the long-snouted Papio. One 
consequence of this backward slope is that in Papio the orbit 
lies considerably behind the level of the last molar ; in 
Macacus the lower border of the orbit is over mp, while in the 
present specimen it is about over the anterior lobe of m3.
