stiff hairs along the sides of its feet and tail, which are 

 doubtless of great assistance to it in swimming. Another 

 shrew, Nectogale, found only in Tibet, is still better pro- 

 vided for an aquatic existence, as it has webs between the 

 toes of both fore and hind limbs. The most remarkable 

 endemic representative of the family of Moles in the 

 Palrearctic Region is the Desman, Myogale, of which there 

 are two species, one found in the Pyrenees, and the other 

 in the streams and lakes of South-Eastern Russia. The 

 external appearance of these animals, however, resembles 

 much more that of a Shrew than that of a Mole. 



Considering that the whole of this Region lies within 

 the temperate zone, the number of its Bats is considerable, 

 although they mostly belong to widespread genera. The 

 Monkeys are represented in the Palsearctic Region by out- 

 lying species of two genera, Macacus and Semnopithecus, 

 which are both abundant in the Oriental Region. To 

 the former of these belongs the well-known Barbary ape 

 (Macacus inuus), which inhabits the Rock of Gibraltar and 

 the Barbary States of Northern Africa, as well as several 

 species of Eastern Asia. Another Macaque (M. tcheliensis) 

 is enabled by its thickened fur to endure the extremely 

 severe climate of the mountains north of Pekin, and is 

 probably the most northern monkey now living.

 Region 



The sub-divisions of the Palsearctic Region recognized 

 by Wallace are four in number; these are — First, the 

 European Sub-region, which includes Europe north of the
