to observe the animal use them for any particular purpose. 

 I am inclined to believe that they are only useful to the 

 animal when fighting ; the tusks of the lower jaw being 

 most valuable weapons of offence, and those of the upper 

 jaw, by protecting the eyes and the fore part of the head, 

 serve as excellent weapons of defence. The babirusa 

 has only been found on the seaward slopes of the Klabat 

 and ' Two Sisters ' hills of North Celebes, but I was informed 

 by Mr. Eijkschroeff that it is also to be met with on the 

 Kelelonde and Saputan mountains of the interior. It is 

 also stated that it may be found in the island of Buru. It 

 is a very shy animal, and never comes near any of the 

 native villages and huts (25), but is nevertheless active 

 and ferocious. 



Of the Anoa depressicornis Wallace says : ' The sapi-utan, 

 or wild cow, of the Malays is an animal which has been 

 the cause of much controversy as to whether it should be 

 classed as ox, buffalo, or antelope. It is smaller than any 

 other wild cattle, and in many respects seems to approach 

 some of the ox-like antelopes of Africa. It is found only 

 in the mountains, and is said never to inhabit places where 

 there are deer. It is somewhat smaller than a small High- 

 land cow, and has long straight horns, which are ringed 

 at the base and slope backwards over the neck ' (83). It is 

 fairly common on the slopes of the Batu Angus in Wallace 

 Bay, and also lives on the more desolate slopes of the moun- 

 tains of the interior. 



A jet-black baboon (Cynopithcais uigrescens) (fig. 11), 

 with small red ischial callosities and a stumpy tail, is as 

 common in the forests of Talisse as it is upon the mainland. 

 A full-grown male measures twenty-three inches from the 

 tip of the nose to the tip of the tail, eighteen inches from 

 the hips to the tips of the toes, and has a span of sixty- four 

 inches. If it were to stand erect, therefore, it would be a
