338 CLASS MAMMALIA. 



count he has been designated by travellers as the pig-tailed 

 or rat-tailed monkey. On this subject we refer our readers 

 to what has been already said in that part of our supple- 

 ment relating to the baboons. 



Finally, the Count proceeds to the monkeys of the New- 

 World, which he thinks with reason, have been very inju- 

 diciously confounded, under the generic names belonging 

 to those of the ancient Continents. On the first discovery 

 of America, it was never suspected that these immense re- 

 gions contained none of the animals peculiar to Africa and 

 India. Creatures were found there with four hands and 

 with fingers, and this relation was deemed sufficient to en- 

 title them to the appellations of apes and monkeys. After 

 noticing the different characters which separate them from 

 the monkeys of the old world, Buffon divides them into two 

 genera, distinguished from each other by the prehensile, 

 and the non-prehensile tail. These are the Sapajous and 

 Sagoins; of the former he admits six or seven species; of 

 the latter six only, which he deems for the most part 

 varieties. 



On the whole, he reduces the monkeys to thirty species : 

 viz., three apes, and one intermediate between the apes and 

 baboons ; three baboons, and one intermediate between the 

 baboons and guenons; nine Guenons, seven Sapajous, and 

 six Sagoins. Any of the rest known at the period in which 

 he wrote, he considers as merely varieties. Such, in brief, 

 is Buffon's arrangement of the Quadrumana, Lemurs ex- 

 cepted, respecting which we deem it unnecessary to add any 

 thing from him, or any one else, in addition to what we 

 have already given. 



The general divisions of this arrangement do not differ 

 materially from the Linnasan, the principal deviations being 

 allocation of some of the species. 



The critical observations of Buffon on the nomenclature 

 of the monkeys, and the methodical distribution which he
