VERTEBRATA. 
THE DIADEM MONKEY. 
this sad experience was lost upon her, as the next day, if tempted in the same manner, she was 
sure to commit the same foolish act. 
" When she was first purchased, the character of this animal was very mild. She had been in 
captivity three years, and as she grew old, it was easy to see that she became mischievous and 
cruel. She made a poor cat that belonged in the house with her, the victim of her cruelty. She 
carried or dogged her round everywhere she Aveut, caressing and beating her by turns. She 
would sometimes fill her mouth with raisins and pieces of apple, and by means of blows and vio- 
lence forced poor pussy to swallow a nourishment that was distasteful to her. In short, she at 
length caused her death by abuse and violence. After that time she was not permitted to tyran- 
nize over any other living animal." 
The White-eyelid Monkey. — This animal is doubtless of the genus Cercopithecus, though 
Bufibn called it a Mangabey, and M. Geoff'roy St, Hilaire denominates it Cercocehus fuliginosus. It 
is probably a native of Western Africa, Its general color is a grayish black. It is not deficient 
in intelligence, and can be taught various tricks. It is petulant and capricious in captivity, but 
otherwise is well-behaved. A specimen in the London Zoological Gardens was remarkably active, 
and caused great amusement by its grimaces, to which its countenance gave peculiar effect. 
The Collared White-eyelid Monkey, C. Ethiops of Geoffroy, resembles the preceding in its 
character and in its general color, though it is marked with chestnut brown upon the upper part 
of the head, and the fore part of the neck is crossed with a band of pure white. It has also long 
white mustaches. It appears to be a native of Western Africa. 
The Talapoin, C. tala-poin^ is a well-known species from Western Africa, and is a favorite, on 
account of its gentle character, its intelligence, and its small size. The general color of the body 
is green above and white below. 
The Diadem Monkey, C. diadematus, is nearly black, the lower parts being mottled with 
green. It is marked with a circular white spot upon the forehead, from which it derives its name.
