The Secretary called the attention of the members to a new spe- 

 cies of Monkey, allied to the green Cercopitheci, living at the So- 

 ciet\^'s Menagerie. 



The Monkeys allied to Cercopithecus sabaus, 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 zoolog}^ Four species have been already distinguished 

 by M. Frederic Cuvier, C. sabaus, fuunus, 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. sabceus and pygarythrus, between which 

 it is intermediate in many of its characters. It may be described 

 as follows : — 



Cercopithecus tantalus. Cere, suprcl saturate flavo-viridis, in 

 artus cinerescens, subtus stramineus ; facie subnigrd, circa ocu- 

 los lividd ; auriculis palmisque fuscis ; caudd fused; apice caudce, 

 mystacibus et perinceo flavis ; tcenid frontali albd. 



Head, back and sides a mixture of yellowish brown and green, of 

 the same mtense shade as that which prevails on the upper parts of 

 the allied species, C. sabceus and pygarythrus ; outer surface of the 

 limbs of a clearer ashy grey colour ; whiskers, throat, breast, belly, 

 and inside of the limbs yellowish white ; tail brown at the root, light 

 grey at the tip ; backs of the hands and feet light grey ; face covered 

 with very short hairs, black on the nose and cheeks, livid flesh-colour 



* Lolus, a caruncle ; vanellus, a Lapwing.
