The Secretary called the attention of the members to a new spe- 
cies of Monkey, allied to the green Cercopitheci, living at the So- 
ciety’s Menagerie. 
The Monkeys allied to Cercopithecus sabeus, observes Mr. Ogilby, 
are now so numerous, that they may be considered to form a sub- 
genus of themselves, at least for all the practical purposes of de- 
scriptive zoology. Four species have been already distinguished 
by M. Frederic Cuvier, C. sabeus, faunus, griseus, and pygarythrus. 
Colonel Sykes has described a fifth, C. albogularis, though it is cer- 
tainly less closely allied to the others than they are among them- 
selves; and there is now a fifth living in the Gardens. This species 
is most nearly related to C. sabeus and pygarythrus, between which 
it is intermediate in many of its characters. It may be described 
as follows :— 
CERCOPITHECUS TANTALUS. Cerc. supra saturate flavo-viridis, in 
artus cinerescens, subtus stramineus ; facie subnigrd, circa ocu- 
los lividd ; auriculis palmisque fuscis ; caudd fuscd ; apice caude, 
mystacibus et perineo flavis ; tenid frontali albd. 
Head, back and sides a mixture of yellowish brown and green, of 
* Lobus, a caruncle; vanellus, a Lapwing.
