instead of six incisors. There are, according to the Count, 

 nine species of Guenons : 1. The Macaques; 2. the Patas; 

 3. the Malbroucs; 4. the Mangabeys; 5. the Mone; 6. the 

 Callitrix; 7. the Moustac; 8. the Talapoin ; 9. the Douc. 

 The imperfectness of this enumeration we need not ad- 

 vert to. 



The ancient Greeks knew but two of these Guenons, the 

 Mone and the Callitrix, which were originally natives of 

 Arabia, and the northern part of Africa. The others, which 

 belong to the southern provinces of Africa and India, were 

 of course entirely unknown in the time of Aristotle. The 

 generic name of Kebos was given to the Mone, by that 

 great philosopher and others, from the variety of colours 

 which it exhibited. 



Two or three ages after Aristotle, we find two new names 

 in Greek writers, callithrix and cercopithecos, both relative 

 to the Guenons or long-tailed monkeys. In proportion as 

 the earth was discovered, and advances were made towards 

 the southern regions of Africa or Asia, new tribes of ani- 

 mals were found, and other specific varieties of the monkey 

 race observed. As the majority of these last were not con- 

 spicuous like the Kebos for variety of colours, the Greeks 

 gave to them the general epithet of Cercopithecos, simply 

 to designate them as having long tails. But having re- 

 marked among them, a Guenon of a greenish fur, and 

 lively colour, they bestowed upon it the name of Calli- 

 thrix which means " beautiful hair." This animal, in fact, 

 is found in the southern parts of the ancient Mauritania, 

 and in the countries near the Cape de Verde. 



The Count fills the" 1 interval between the baboons and 

 guenons with the Maimon as an intermediate species. He 

 has a general resemblance to the Guenons, says this writer, 

 ut with the large muzzle and short tail of the baboons : is 



native of Sumatra, and is the only monkey of either of 

 these families, whose tail is destitute of hair; on this ac-
