THE GEOGRAPHY OF MAMMALS 



outside the limits of this Sub-region. A fifth endemic 

 genus of rodents is Ellobius, which is thoroughly adapted to 

 a subterranean life, having very short limbs and tail, and 

 rudimentary external ears. The only two known species of 

 this genus are restricted to the Eremian Sub-region. 



The Eremian Carnivora, as is usually the case with this 

 group, are mostly widespread, and this is also the case with 

 the Bats. The Insectivora are not very numerous, but one 

 genus is peculiar to the Sub-region ; this is Diplomesodon, 

 a little shrew-like animal of terrestrial habits found in 

 the Kirghiz steppes. Another genus, Macroscelides (the 

 Elephant-shrew), though typically Ethiopian, has one species 

 that extends into this Sub-region in Algeria and Tunis. 



The Monkeys are represented in the Eremian Sub- 

 region by one species only, the well-known Barbary Ape, 

 (Macacus inuus), which is found in Algeria and Morocco. 



The genera that occur in the Eremian Sub-region are 

 shown in the following table, which may be compared with 

 the corresponding table appended to the Europasian Sub- 

 region : —
