THE MAMMALS OF EGYPT. 
of the limb being rich dark brown, but a short way above the wrist the yellow annuli 
again appear mixed with the dark brown. The hind limb generally in its lower portion 
is almost uniform yellow, owing to the absence of the black tips, but the dorsum of the 
hind foot is dark reddish brown speckled with yellow. The first half of the tail is 
concolorous with the back, but the remainder is rich yellowish, concolorous with the 
lower parts of the hind limbs. The under parts are annulated like the upper, whilst 
the inner surfaces of the limbs conform to the general colouring of the under surface.

There is a skull from Muanza, on the southern shore of Victoria Nyanza, which 
belongs to the P. anuhis group, but which Mr. Matschie at first thought was the adult 
male of the species from Unguru, named by him C. langheldi from the skin of a female 
which is preserved in the Hamburg Museum along with its skull. The latter specimen 
was afterwards referred correctly to the East Coast baboon, P. cynocephalus of this work, 
while for the Muanza baboon he proposed to retain the term P. langheldi ; but as that 
name was undoubtedly bestowed on the animal from Unguru, it must relapse into a 
synonym of P. cynocephalus. 
The measurements of this Muanza skull (Berlin Mus. 8386) I have given on p. 40, 
no. 9. Unfortunately the basioccipital and greater part of the basisphenoid have been 
destroyed. While all the teeth are through, the condition of the premaxillary and 
some of the other sutures indicates that only a slight capacity for growth still existed. 
Besides this skull, I examined three other adult male skulls from Muanza, exactly 
similar, but unfortunately not one of them is accompanied by a skin. They vary 
remarkably in orbital breadth and in the breadth of the muzzle. Thus in 8386 the 
transorbital breadth is 91 mm., and in 8387, 80 mm. At the base of the muzzle of- 
8386 the breadth is 51 mm., and in 8387, 39 mm. The breadth across the muzzle 
opposite to the end of the nasals in the former is 43 and in the latter 40 mm. 
A skull from Samui collected by Werther' is that of an immature male; the third 
molars are not through the jaw, and the canines only partially so. Its forehead, more¬ 
over, has the broad character of youth. The extreme length of this skull is 120 mm. 
It is distinguished from the foregoing adult skull by its larger teeth. Thus the second 
lower molar of skull 8386 measures 12-5 mm., whereas the corresponding tooth of 
this skull is 14-2 mm. The upper incisors are wanting in 8386, but the incisors are 
present in the lower jaws of the two skulls. In the former a mesial incisor is 7 mm. 
broad and in the latter 9 mm. The upper incisors of this young skull are as large as 
the incisors of the baboon from Dar Eertit collected by Schweinfurth.
