I VI THE GEOGRAPHY OF MAMMALS 



whereas in Java they are replaced l>y slightly different 

 forms. The Philippines, though connected with Borneo l>y 

 two chains <>f islands, so that the straits separating the 

 group from Borneo are nowhere rery wi<l<!, contain it poor 

 mammal fauna as compared with Borneo. Only about 

 fourteen genera, exclusive of bats, have reached these 

 islands, and, with one exception, these are all widespread. 

 But ii must be recollected that the Mammal-fauna of the 

 Philippines is still very imperfectly known. 



The following table gives the figures relating to the 

 distribution of the genera within the Sub-region (excluding 

 bats): —

As regards the Philippines, the total number of mammal 

 genera (exolusive of bats) is fourteen, thirteen of which 

 ooouralsoin the Malay Peninsula and islands; one is oon- 

 fined to the Philippines alone; in addition five Malayan 

 genera reach Palawan, a Large island Lying between Borneo 

 and the Philippines. 1 



Although the Malayan Sub-region does not contain any 

 endemic genera of Ungulates, there is one form the dis- 

 tribution of whioh is so remarkable that special attention 

 must be drawn to it. This is the Tapir, one species of
