G RIVET, GREEN MONKEY, AND VERVET 
The first glance at one of these monkeys will detect a peculiar sheen of the fnr, that bewilders 
the eye and conceals the precise color. If, however, the hairs are examined separately, each 
hair will be found to be varied in color several times, black and yellow being the principal 
colors. First the hair will be black for a part of its length, then yellow, then black again, and 
so on to the tip. As the black has something of a bluish tinge in it, the mixture of the yellow 
and blue gives an undefined greenish Hue, as to cause the name of Green Monkey to be given 
to the animal. 
The Cercopitheci are remarkable for the singularly large development of the cheek pouches, 
which seem to possess an illimitable 
power of extension, and to accumu- 
late a strange medley of articles. 
Supply one of these monkeys with 
nuts or biscuit, and he will contrive 
to put the greater part of the food 
into his cheek pouches, only eating 
a small portion at the time. 
I never knew but one instance 
when the pouches were quite full, 
and even then the monkey was a 
small one, and the nuts were large. 
The little creature was liberally 
gifted with nuts, with the special 
purpose of ascertaining the capabil- 
ities of the pouches, and after dilat- 
ing its cheeks to a wonderful extent 
with large “ cob ” nuts, it was at last 
compelled to empty them into its 
hands. 
These pouches have been aptly 
compared to the stomach of a rumh 
nant animal, and are employed in 
much the same manner. By meana 
of the possession of these natural 
cupboards, the monkey is enabled to. 
make little incursions, to eat as 
much food as hunger demands, and 
to carry away sufficient nourishment 
for one or two meals more, without

It is worth notice that the word “ monkey ” is derived from the name of this group, the 
Mona. The diminutive of Mona is Monikin, the transition from which word to our “monkey” 
is sufficiently evident. 
The GrBivET, or Tota, as it is called by some writers, is of a sombre green color ; the green 
being produced, as has been already mentioned, by the black and yellow hair. The limbs and 
tail are of a grayer tint than the rest of the body, the yellow portion of the hair being changed 
to a dull white. The inside of the limbs and the abdomen are slightly tinged with white. In 
the male animal the canine teeth are rather protuberant, showing themselves beyond the lips. 
The naked skin of the face, ears, and palms, is black, dashed with that deep violet hue that is 
found in so many of the monkeys. At each side of the head, the white hairs stand out boldly, 
whisker fashion, and give a very lively character to the head. It is an African animal, and. 
common in Abyssinia. 
The Green Monkey, is sometimes called the Callithrix, or Beautiful-haired Monkey, on 
account of the exquisitely delicate marking of each separate hair, The inside of the limbs is
