THE ORIENTAL REGION 147 



sentatives of the marsupials characteristic of the Australian 

 Region. Those consist of two species of Phalcmger, which 

 differ from those of the Australian islands only in slight 

 particulars. 



The next interesting animal of this fauna is the 

 Babirussa, a wild pig remarkable for the enormous size 

 of its upper and lower canine teeth, which form, as it 

 were, two pairs of horns on the upper side of the head. 

 Another peculiar Ungulate, now generally referred to 

 the widespread genus Bos, is the Anoa. which shows 

 many primitive characters, and is entirely confined to 

 the island. 



The Mice and Squirrels of Celebes are fairly numerous., 

 and most of the species are peculiar to the island : one rat 

 forms a special genus. 



Carnivores are very scarce in Celebes : Insectivores 

 have not been recorded at all. The Bats,, which are 

 numerous,, comprise a considerable number of Australian 

 forms, and one peculiar genus. 



Among the Primates. Ta/rsius of the other Malayan 

 islands is also found in this Sub-region, and one Monkey, 

 Macacu8 mawrus, seems to be restricted to it. Finally, 

 one of the most remarkable of the animals of the island 

 is the Black Ape of Celebes, belonging to a genus (Gyno- 

 piihecus) intermediate between the Macaques and the 

 Baboons. Gynopithecus appears to have found its way 

 from Celebes into the adjoining island of Batchian. which 

 belongs to the Australian Region.

 region arranged in a form like those of the other 

 Sub-regions : —
