164 FAMILY SIMIAD^E. MONKEYS AND BABOONS. 



distinguish it. These Monkeys have cheek-pouches, callosities, 

 well-developed thumbs on their hands, and long tails ; and they 

 are further known by the annulated or ringed character of their 

 fur, which gives them a speckled appearance. They are slender 

 in their structure, and light and agile in their movements ; and 

 their characters display vivacity, impetuosity, and restlessness, 

 with occasional caprice and petulance. They are a pre-eminently 

 sylvan race, never abandoning the forests, and living chiefly 

 upon wild fruits and the seeds and buds of trees, with an occa- 

 sional intermixture of insects and birds 1 eggs. The true Cerco- 

 pitheci are confined to Africa ; but there are a few species of 

 Monkeys in Asia (commonly included among the Macaques)^ 

 which approach the Baboons in their general characters, but 

 which are probably to be united with this genus, as they agree 

 in its essential characters, except in having a shorter tail; 

 and by these we should make a natural transition to the next 

 tribe. 



154. The Baboons are distinguished from the other Quadru- 

 mana, not only by the peculiar distinctive characters which have 

 been already mentioned ( 147) ; but also by certain obvious, 

 though less easily defined, characters. The body is much more 

 massive, and the strength is increased in even greater proportion. 

 The projection of the muzzle, at the ends of which the nostrils 

 are situated, gives to the face much more of the aspect of the 

 Carnivora; and they move much more exclusively upon all- 

 fours, than do any of the other SIMIADJS. Their temper is 

 gloomy and sullen ; and they exhibit a considerable degree of 

 ferocity when they are attacked, together with a large amount 

 of malice and revengeful feeling when they are offended. These 

 characters, however, are not exhibited in an equal degree by the 

 two genera of which the tribe consists, Papio and Cynocephalus; 

 for in the animals belonging to the former group, they are 

 softened down, as it were, so that the line of separation between 

 them and the Monkeys is by no means distinct ; whilst in those 

 of the latter, they are manifested in their highest degree. It is 

 an interesting circumstance, that these two genera should be 

 restricted to different quarters of the globe, the Papios being
