Cercopithecus rufo-viridis, 1. Geoffr. St. Hilaire, Compt. Rend. 
xv. p. 1038; Arch. Mus. ii. p. 564. pl. 4. 
In June 1859 we received a Monkey, obtained, living, by Com- 
mander Bedingfield, R.N., in the mouth of the Zambesi River when 
in company with Dr. Livingstone’s expedition. It agrees so nearly 
with the description and figure of M. St. Hilaire’s Cercopithecus 
rufo-viridis, that I have no doubt of its belonging to that species. 
The feet of our specimen are rather darker-grey in colouring, which 
is really almost the only difference I can make out. As the typical 
example of this species at Paris was the only one previously known, 
it is of much interest to possess a second, coming from a determinate 
locality. Referring to Dr. Peters’s ‘Zoology of the Mozambique,’ 
we find no species indicated as likely to be intended for the present, 
though the true C. pygerythrus (a species generally confounded 
with the South African C. delalandit) is said to occur in that coun- 
try. The nearest ally of C. rufo-viridis is the Grivet (C. griseo- 
viridis, Desm.) of Eastern Africa. 
4. CynocepHatus anusis, F. Cuv. & St. Hil. 
The Society have lately purchased of Mr. W. C. Finlason a fine 
young male example of a Cynocephalus, which that gentleman brought 
home with him from Lagos in the Bight of Benin, on the west coast 
of Africa. It was captured when quite young, about midway be- 
tween Lagos and Abbeokuta. 
Mr. Finlason informs me that it is very seldom that these animals 
can be obtained, the natives having a fearful horror of their strength 
and ferocity when attacked. 
This Cynocephalus seems to be the Anubis, as figured in F, Cu- 
vier and G. St. Hilaire’s ‘ Mammiféres ’ (livr. 50), a species not ge- 
nerally recognized by systematists. It agrees perfectly with the 
example lately in the Society’s collection, but now in the British 
Museum, which was named Cynocephalus anubis by Mr. Water- 
house*, and with other similar specimens, which all bear the same 
name, in our National Collection. It is very different from Cynoce- 
phalus babuin of Eastern Africa, of which Wagner+ has made the 
C. anubis a variety, and is more like C. sphinz of Senegal. The Cyno- 
cephalus olivaceus of Geoffroy St. Hilaire’s Catalogue of the French 
National Collections is undoubtedly of this same species, our speci- 
men agreeing perfectly with the characters there given, and being 
from the same locality. The most noticeable points in this Cyno- 
cephalus are the very elongated black face, and the uniform dark 
olive-green fur, traversed below the surface with annellations of 
yellow and black. 
I may take this opportunity of remarking that Mr. Ogilby’s Cy- 
nocephalus thotht, of which the type specimen is now also in the 
* See ‘Catalogue of the Mammalia preserved in the Museum of the Zoological 
Society of London,’ ed. 2, 1838, p- 8, sp. 51 A.
