is quite distinct in colour from its parents, being pale 
yellow. 
Sometimes associated with these is another Semnote 
of a very pale sandy yellow colour, with a distinct crest 
which is more or less tipped with blackish, and hence this 
species is known as 5. melalophus , and it inhabits the 
island of Sumatra. There is also another Semnote occa¬ 
sionally exhibited, viz., the Purple-faced monkey of Ceylon, 
S', cephaloptenis , so named on account of its prominent 
white whiskers. 
That beautiful African species, Cercopithecus diana , or 
the Diana Monkey, occupies a small cage in this house. 
It is a native of Western Africa. 
The Marmosets, some of which are exhibited in a 
small cage, constitute one of the Divisions of the 
American monkeys, distinguished by having 32 teeth, 
the same number as in man, and by their tails not being 
prehensile. They are the smallest of the monkey kind, 
and are generally characterized by small round heads, 
and by their hands and feet more resembling the paws 
of a bear than the hands and feet of an ordinary monkey : 
hence they are sometimes called the Bear Monkeys. It will 
be observed that the nose conforms to the Platyr- 
rhine type. Unlike other monkeys they are insectivor¬ 
ous, or even carnivorous in their diet, and have been known 
to catch fish and eat them. They are not credited with 
much intelligence, but their affection to one another is very 
great, and the parents bestow every care on their off¬ 
spring, carrying them about, clinging on to their bodies, 
nestling in the thick warm fur. These pretty little 
animals are the size of small squirrels and jump about 
like them from bough to bough of the tallest trees.
