j^pes and their Allies. ^X^ 



"adjoined Table, q. v., one will suffice for illustration. The 

 collared and un collared mangabeys are instances of two species, 

 each consisting of varieties dependent on trifling and often 

 transitory marks. These two species are much more inti- 

 mately allied than either of them to the Rolowai or the Mal- 

 brouk, these forming the true genus Cercopithecus^ as those 

 Cercocebus, would commonly be called subsections of a sub- 

 genus, contained in one of the sections of the genus Simia. 

 Again, the Mangabeys [or genus Cercocebus] are more closely 

 connected to the Malbrouks [or genus Cercopithecus] than 

 either of them to the Apes, Baboons, or Howlers; which 

 further alliance, by distinguishing the true monkeys from their 

 associates, has been called a subgenus ; in fact, it is the dis- 

 tinction of a kind, and indicated by the termination, dco or idtp, 

 affixed to the names of the most important or most familiar, 

 I. <?., the normal genus, — in this case Cercopithecus, — and 

 hence the group is called Cercopithecidse, or Cercopithedae, 

 i. e.y Monkeys, or the monkey kind. But as apes, baboons, 

 monkeys, &c., are more nearly allied than either to the Titidae 

 (Ouistidse,) or Lemuridae, (the genera Ouistitis and Lemur, 

 of Cuvier and Linnaeus,) they form together the Pithecatae 

 [the Ape or Monkey race] : and these three races, i. e., the 

 genera Simia and Lemur of Linnaeus, with the Ouistitis of 

 Cuvier, are connected as a district or type, by their all possess- 

 ing hand-like feet, [their indicative character,] under the name 

 Quadrumana, four-handed; or rather Manupeda, hand- footed 

 beasts : thus entirely avoiding that intricacy of genera and sub- 

 genera, sections and subsections, which inevitably occurred 

 when the whole of these animals were considered as belonging 

 to only two genera, viz., Simia and Lemur. 



To define the species and genera, or even to enumerate the 

 whole, would be without my plan, (which is to give merely an 

 outline or prodromus,) and for these I must at present refer to 

 the works of Pennant, Shaw, Audebert, GeofTroy, Cuvier, Illi- 

 ger, and others ; my object now is to condense into a prac- 

 tical form, to draw as it were into a focus, those general views 

 which must be sought in several languages, and are spread 

 through many volumes: some few, however, of the characters 

 of the type, races, and kinds, must not be omitted.
