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 

 larvatus) of Borneo, of which a fine male example is placed in the 

 centre of the case. (2) The Colobi (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 (Colobus 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- and 6 ^ 

 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 3> 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 Cebida, 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-
