MACAQUES.

(C. pyrrhonotus), variegated with differently 

 distributed coloured spots, and mostly also 

 furnished with curious pencils of hair, beards, 

 and tufts like the Semnopitheci. These are 

 the chief typical species. The last-mentioned 

 species, a native of Nubia and Darfur, is 

 common in our zoological gardens, and is 

 agreeable in its ways when young, but sullen 

 and tiresome when old. The Diana monkey 

 (C. diana] is a pretty little creature of a slate- 

 gray colour, which becomes darker on the back 

 and inclines to brown ; its face has a triangular 

 white border, which ends in a long pointed 

 beard, and is continued clown the neck, 

 breast and arms to the fore-arm ; its legs 

 are white on the inside, and it is provided 

 with a long tail without a terminal tuft. 

 It belongs to West Africa, and is often 

 found along with the mona in our 

 zoological gardens and monkey-houses. 

 From the mona, which is similarly 

 marked, it is distinguished by the pos- 

 session of a long beard. In its behaviour ' 

 it makes itself a favourite by its good- 

 nature. 



The Green Guenon (C. sabczus) is a 

 creature of more powerful frame, ap- 

 proaching more nearly to the macaques; 

 olive-green on the back, with a blackish 

 cap on the crown. On Plate IV. a 

 troop of this species is represented 

 surprised in the plundering of a maize- 

 field. The alarmed animals are trying 

 to save their booty and their young by 

 a hasty flight, while their leader on 

 the fence keeps watch for the threaten- 

 ing danger. 



All the guenons live in troops, often count- 

 ing more than a hundred head. They are 

 cunning thieves, and subordinate themselves 

 in all their movements to the old male which 

 acts as their leader. Like most other mon- 

 keys they have manifestly a means of com- 

 municating with one another through the 

 modulation of their throat-tones. On account 

 of their depredations they are thoroughly 



detested by the natives, who catch them 

 chiefly with nets under which they place 

 fruits as bait. They are extremely fond of 

 eggs, but do not despise insects. 



Macaques (Macaais). 



With a solitary exception Asiatic monkeys, with a rather 

 thickset frame, protruding muzzle, tolerably powerful jaws, 

 simple stomach, cheek-pouches, and a tail which never 

 grows longer than the whole body. 



According to the degree of development 

 of the tail several sub-genera have been estab- 

 lished under this genus also: first, those with

long tail, to which belong the Java Monkey 

 (M. cynomolgtts) and the Malbruk or Bonnet- 

 monkey of Malabar ; next those with only 

 a moderately long tail, such as the Wanderoo 

 (M. silenus) and the Boonder (M. rhesus); 

 and lastly the Magot or Barbary Ape (Inuus 

 or M. ecaudatus}, with a short skinny stump, 

 found in Algeria, Morocco, and on the rock 

 of Gibraltar.
