Also 7 species of bats, of 
which 5 are peculiar. 
The first — a large black ape — is itself an anomaly, since it is not 
closely allied to any other form of quadrumana. 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. 1 We have already seen reason 
to suppose that it has been carried to Batehian, and there is some 
doubt about the allied species or variety (C. niger) 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, but 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 Moluccas, introduced species. (5.) Anoa depressicor- 
nis. This is one of the peculiar Celebesian types; a small straight- 
horned wild-bull, anatomically allied to the buffaloes, and some- 
what resembling the bovine antelopes of Africa, but having no 
near allies in the Oriental region. (6.) Sus Celebensis ; a peculiar 
species of wild-pig. (7.) Babirusa alf urus ; another remarkable 
type, having no near allies. It differs in its dentition from the 
typical Suidte, and seems to approach the African Phaeochceridse. 
The manner in which the canines of the upper tasks 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 
Gymnomys, allied to Australian species. 10. Cuscus. This typical 
1 The general form of the skull agrees best with that of Cynocepkalui 
mormon, the largest and most typical of the African baboons ; while the 
position of the nostrils brings it nearer the macaques.
