ZOOGBOGRAPHICAL REGIONS 219 



going description, but some further details may be 

 added. The region is almost equally characterized by 

 the forms which are present, and by those which are 

 absent. Among the Primates it possesses the gorUla 

 and the chimpanzee, two pecuhar forms confined, as 

 we have seen, to a relatively small part of the con- 

 tinent. Monkeys are represented by five peculiar 

 genera with many species, lemurs by two or three 

 genera and some eight species. Pruit-bats are fewer 

 thain in India. Insectivores are peculiar and primitive. 

 Thus we have jumping-shrews, the aquatic potamogale 

 and the golden mole, the latter beKeved to be allied 

 to the curious tailless hedgehog or tenrec of Madagascar. 

 Among the carnivores an interesting feature is the 

 presence of two peculiar dogs, belonging to the two 

 genera of Lycaon and Otocyon, the latter having very 

 primitive teeth. We have already spoken of the 

 absence of bears, and it is noticeable that the weasel 

 aUiance is scantily represented. 



So much has been already said of the ungulates (p. 129 

 et seq.) that a few general statements may suffice. 

 Goats and sheep are practically absent, and with one 

 exception so are true pigs of the genus Sus, though wart 

 hogs, bush pigs, river hogs, and the hippopotamus occur. 

 There is no tapir and no camel, but rhinoceroses, 

 elephants, chevrotains, and several kinds of horses 

 occur, as well as the curious hyrax and peculiar forms 

 like the girafEe and okapi ; antelopes are abundant. 



In regard to the rodents a peculiar feature is the 

 absence of the true flying squirrels and their replace- 

 ment by the peculiar family of Anomaluridae (cf . p. 109). 

 The Edentates are represented by the curious aard-vark 

 (Orycteropus), as weU as by pangolins. 



The birds are not so abundant nor so beautiful as
