The Vervet Monkey ( Cercopithecus lalandii ), the Green 
Monkey ( Cercopithecus callitrichus ), the Pat as or Red Mon¬ 
key ( Cercopithecus ruber), the Lesser White-nosed Monkey 
{Cercopithecuspetaurista), the Mozambique Monkey ( Cerco¬ 
pithecus rufo-viridis ), the beautiful Diana Monkey {Cercopith¬ 
ecus diana ), and the Mangabey {Cercocebus fuliginosus), are 
all natives of south and west Africa. 
The Macaques form a large genus of monkeys, some of 
them of large and powerful build, and, for the most part, of 
savage and treacherous dispositions. They are all natives of 
Asia and the adjacent islands. Among them are the Common 
Macaque {Macacus cynomolgus), the Pig-tailed Macaque 
{Macacus nemestrinus), the Rhesus Monkey {Macacus ery- 
thrceus), the Toque {Macacus pileatus ), the Bonnet Ma¬ 
caque {Macacus radiatus), the Moor Macaque {Macacus 
maurus ), and the Ashy-black MAcaque {Macacus ocreatus). 
The Black Ape ( Cynopithecus niger ), from the Philippine 
Islands, is related to the last genus. 
The genus Cynocephalus, or Dog-headed Monkeys, form the 
group known as Baboons, among which are some of the largest 
and most fierce of the order. The Chacma {Cynocephalus 
porcarius), the Guinea Baboon {Cynocephalus sphinx ), the 
Mandrill {Cynocephalus mormon ), the Drill {Cynocephalus 
leucophceus ), and the Anubis Baboon {Cynocephalus anubis ), 
are natives of Africa. They can all be recognized by their 
long, dog-like noses, in some cases projecting beyond the 
lips. 
Although these monkeys are coarse and brutal in their be¬ 
havior towards man, they are capable of a high degree of at¬ 
tachment among themselves. 
A remarkable instance of this is given by Brehm, an African 
traveler of undoubted veracity, who once saw a troop of Ba¬ 
boons crossing a valley,—while so doing they were attacked 
by his dogs, and fled up the hills, leaving behind one young 
one, which, unable to run away, had climbed a rock in the 
middle of the valley. Those on the hillside deliberated for 
a time, and finally a large male returned to the spot, drove 
off the dogs, picked up the young one, and retreated with it 
in safety. 
The American monkeys differ in many respects from the 
preceding group; in dentition, which in the Cebidce , includ¬ 
ing all but the Marmosets, has one pre-molar tooth added on
