CHAP, siii.] THE AUSTRALIAN REGION. 427 



Celebes as far as at present known, though many small species 

 may yet be discovered. 



1. Cynopithecus nigrescens. 7. Barbirusa alfiirus. 



2. Tarsius spectrum. 8. Sciurus (5 peculiar sp.) 



3. Viverra tangalunga. 9. Mus (2 peculiar sp.) 



4. Cervus hippelaphus. 10. Cuscus (2 peculiar sp.) 



5. Anoa depressicornis Also 7 species of bats, of 



6. Sus celebensis. which 5 are peculiar. 



The first — a hxrge black ape — is itself an anomaly, since it is not 

 closely allied to any other form of cpiadrumana. Its flat projecting 

 muzzle, large superciliary crests and maxillary ridges, with the form 

 and appearance of its teeth, separate it altogether from the genus 

 Macacus, as represented in the Indo-Malay islands, and ally it 

 closely to the baboons of Africa.^ "We have already seen reason 

 to suppose that it has been carried to Batchian, and there is some 

 doubt about the allied species or variety {C. nigcr) of the Philip- 

 pines being really indigenous there ; in which case this interesting- 

 form will remain absolutely confined to Celebes. (2.) The tarsier 

 is a truly Malayan species, Imt it is said to occur in a small island 

 at the northern extremity of Celebes. It might possibly have been 

 introduced there. (3) and (4) — a civet and a deer — are, almost cer- 

 tainly, as in the INIoluccas, introduced species. (5.) Anoa depressicor- 

 nis. Tliis is one of the peculiar Celebesian types; a small straight- 

 horned wild-bull, anatomically allied to the buffaloes, and some- 

 what reseml)ling the bovine antelopes of Africa, but having no 

 near allies in the Oriental region. (G.) Sus Celebensis ; a peculiar 

 species of wild-pig. (7.) Bidnrusa alfurus ; another remarkable 

 type, having no near allies. It differs in its dentition from the 

 typical Suidiie, and seems to approach the African Phacochreridte. 

 The manner in which the canines of the upper tusks are reversed, 

 and grow directly upwards in a spiral curve over the eyes, is 

 unique among mammalia. (8.) Five squirrels inhabit Celebes, and 

 all are peculiar species. (9.) These are forest rats of the sub-genus~ 

 (T?/?n%o?n?/.s, allied to Australian species. 10. Cuscus. This typical 



^ The general form of the skull agrees best with that of Cynocephalus 

 mormon, the largest and most typical of the African baboons ; while the 

 position of the nostrils brings it nearer the macaques.
