color and brownish silvery gray between the hind legs. The exterior 
of the hind legs is blackish, but the annulations of white, though not 
prominent, are perceptible. In a small area on the undex side of the 
base of the tail and about the anus the hair is cinnamon red. There 
is a tinge of this color in the same region in the adults, but it is not 
conspicuous. 
The skull of the largest specimen, compared with a skull of C. mond, 
shows many differences. The nasal region is much higher and more 
prominent. The anterior nares are much larger. The nasal bones 
themselves are longer and broader. The orbits are higher than broad, 
which is not the case in-C. mona. The palate is longer and narrower, 
and the posterior palatine foramina, in this specimen at least, are situ- 
ated opposite the posterior margin of the last molar, and not that of the 
penultumate molar, as in C. mona. The dimensions of this skull are as 
follows:

This skull indicates that the individual to which it belongs is not 
young. The occipito-sphenoidal suture is closed and that between the 
squamosal and parietal bones is partially obliterated. The teeth are 
worn nearly to the roots in an irregular manner.

Cercopithecus sabzus (Linn.). 
The collection contains one young specimen from Taveta. It is 
apparently a male. It presents no peculiarities of coloration, except 
that the tail is dusky at the end rather than whitish, but it appears to 
have been injured during life, and has not its full length. The ears are 
clothed within with long whitish hairs, which extend beyond the margin 
of the ear. 
The skull shows the milk dentition. All the sutures are open, except
