DOG-TAILED BABOON. 7 



The Vaulting or Lesser White -nosed Monkey. 



Cercopithecus petaurista, Geoff., Zool. Gard. vi. 137. 

 This very elegant little species is seldom seen in our 

 menageries. Two, however, have been at different 

 times in the possession of the Zoological Society, and 

 have been thus described. The Blanc Nez, or white- 

 nosed monkey, is one of the smallest, and at the same 

 time one of the most curiously marked, among its own 

 tribe. It may always be recognised at the first glance 

 by the white patch which occupies the extremity of its 

 nose, and which occurs only in one other species, the 

 C. nictitans, or white-nosed monkey of Pennant. In 

 manners and disposition it is lively, active, and gene- 

 rally good tempered : it was, however, by no means 

 familiar, and appeared to be particularly anxious to 

 conceal its face ; crying out and kicking with all its 

 might, when handled for the purpose of inspection. It 

 is a native of Guinea, and seems to be pecuharly sus- 

 ceptible of cold ; seldom bearing, for any length of time, 

 the rigour of a European climate. 



The Dog-tailed Baboon.

 faced Baboon, Shaw, i. 32. Auduh. Hist. 4. § 2. f. 5. Mal- 

 brouck, Griff. Cuv. i. 266. 



This animal, called by the French the Malbrouck, is 

 sometimes seen in our menageries, although neither his 

 appearance nor disposition place him in competition 

 with the more elegant and docile species of this family. 

 The length of the hinder limbs evinces the peculiar 

 adaption of his structure for climbing and living among 

 trees ; this disproportion of hands and feet, while it 

 renders his progress upon the ground slow and awkward, 

 is no impediment in climbing, but imparts, on the con- 

 trary, a wonderful degree of agility in leaping from 

 branch to branch, and from tree to tree. In a state of 

 nature, these animals congregate in large troops, and Uve 

 in the thick virgin forests of Tropical Asia. They are 

 said to annoy the traveller both by the petulance of their
