96 THE GEOGRAPHY OF MAMMALS 



the six Ethiopian families three are not found elsewhere, 

 and one of the others only extends into the Palsearctic 

 Region as far as Northern Africa. This is the family of 

 elephant-shrews (Macroscelidse). 



The Bats of this Region present few particular features 

 of interest, belonging nearly all to widely spread genera 

 of widely spread families. Among those that are peculiar 

 the most important is Epomophorus, containing eight or 

 ten species of large fruit-eating bats, with long rather 

 horse-like heads, and expansible and peculiarly folded 

 lips. The Epomophori seem to take the place, in Africa, 

 of the genus Pteropus, which, although represented by 

 several species in Madagascar, and even in the Comoros 

 (which are separated from the mainland by only a com- 

 paratively narrow strait), is entirely absent from the 

 African mainland itself. 



Among the Lemurs we have two families, one con- 

 taining only a single species {Chiromyidx) confined to 

 Madagascar, the other {Lemuridm) containing a large 

 number of genera, of which ten are confined to Mada- 

 gascar, two are found on the mainland of Africa, and 

 the other two in the Oriental Region. 



The Quadrumana of the Ethiopian Region, which are 

 entirely absent from Madagascar, belong to two families, 

 both of them shared with the Oriental. The genera, 

 however, six in number, are all without exception con- 

 fined to this Region. In the first place this Region is the 

 only home of the Gorilla and Chimpanzee (Fig. 18, p. 97), 

 two of the Apes most nearly allied to Man in structure, 

 and usually placed at the apex of the mammalian series. 

 The Colobs, or Thumbless Monkeys (Colobus), represent 

 the Langurs (Semnopithecus) of the Oriental Region in
