Bihos bantetig (Raffles). 



Skull of an adult female. 

 Horns of an adult specimen. 

 Horns of a young individual. 



Dr. Nieuwenhuis relates that the animal is living along 

 the upper and middle Mahakkam, Batang, Badjang and 

 Upper Silat. It frequents in small troops principally young 

 bush and shrubs; the Baham-men hunt it very seldom as 

 they do not like its flesh as a meat ; the Malay however 

 are more fond of it. 



The indigenous men (so Dr. Nieuwenhuis reported) dis- 

 tinguish two varieties : a large black one and a smaller red 

 form. The photo (plate 2) and the skull belong to spe- 

 cimens of the black variety. It is well known that the 

 adult female is more reddish , not so dark colored as the 

 adult male. According to Dr. S. Muller the Dajaks along 

 the Doeson-river call the (black-colored) adult animal 

 Roempoe and the (red-colored) calf Banteng — and by 

 that way I explain Dr. Nieuwenhuis' black and red varieties.
