MONKEYS.

medium size, with long tails, small posterior callosities, and 
generally rather short crisp fur, nearly uniform in colour, natives 
of India, China, and the East-Indian Archipelago. The most 
striking species both in form and colour is the Proboscis Monkey 
(so called on account of the remarkable length of its nose) [Nasalis 
larvatiis) of Borneo, of which a fine male example is placed in the 
centre of the case. (2) The Culohi (Case 4), closely allied to the [Case 4.] 
last, but natives of Africa ; some are dull rufous or grey, and others 
finely marked with sharply contrasting black and white, with 
long tufted tails, noticeably the Guereza [Colohas guereza), which 
has on its side a peculiar fringe of long white hairs reaching quite 
down to the ground, and probably serving as a protection from the 
fierce African sun. (3) The long-tailed African Monkeys (Cerco- 
pithecus) (Cases 3 & 4), provided with cheek-pouches in which 
food can be temporarily stored, large posterior callosities, and 
extremely long tails ; many of them are brilliantly coloured, 
as for example the Mona Monkey [C. mono). (4) The Macaques, 
chiefly inhabitants of Southern Asia, one species {Macacus inuus) 
occurring in North Africa and leading a precarious existence on [Cases 5 
the rock of Gibraltar (Cases 5 & 6). (5) The Baboons [Cyno- 
cephalus), hideous animals with powerful teeth, projecting jaws, 
nearly equal fore and hind limbs, and dull-coloured fur, natives 
of Africa and Arabia (Case 6) : one species, the Mandrill {Papio 
maimon), has a short stumpy tail, and a perfectly naked face, the 
skin of which is brightly marked with blue and vermilion ; all the 
others are dull-coloured animals, with well-developed tails. 
All the species hitherto enumerated, from Man down to the 
Baboons, are classed together as one group, the Catarrhini^, or 
narrow-nosed,^^ distinguished by the very narrow division between 
their nostrils and by having only 32 teeth; they are entirely re- 
stricted to the Old World. The Monkeys following form the 
group of Platyrrhini, or “ broad-nosed Monkeys, peculiar to 
America, and characterized by their widely separated nostrils, 
frequently prehensile tails, less perfectly opposable thumbs, &c. 
The first family of this group is the CeUdce, comprising : — (1) The [Cases 7 
Spider-Monkeys {Ateles) (Cases 7 & 8), remarkable for their ex- 
tremely long and slender limbs — of which, alone among the Platyr-
