BORNEON MAMMIFERS. 485 



whether it belongs to the two-horned species of Sumatra, 

 or the one-horned species found in Java ; the Leopard of 

 Borneo appears to be the Felis macrocelis, although the 

 existence of a much larger carnivorous quadruped may 

 be inferred from the long sharp canine teeth worn in the 

 ears of the Orang Sagai, and which appeared to me to 

 have belonged to an animal nearly as large as the Royal 

 Tiger, a variety of which, indeed, is found both in Java 

 and Sumatra. The Dyaks, in explaining their mode of 

 killing this tiger by surrounding him in great numbers, 

 and then shooting him with sumpits or poisoned arrows, 

 described him as being large and fierce, and living among 

 the mountains. Mr. Brooke has ascertained the exist- 

 ence of three species of Orang Utans in Borneo; namely, 

 the Simla Wurmbii or Mias Pappan, the Simia Morio or 

 the Mias Kassar, and the Mias Rambi, which he states is 

 either the Simia Abelii, or a fourth species ; he observes, 

 moreover, that " the existence of the Sumatran Orang in 

 Borneo is by no means impossible." The Wou-Wou of 

 Borneo is of a darker colour than the Javanese species, 

 and has been named Hylobates concolor or H. Harlanii; 

 it is represented in India by the Great Gibbon or Hylo- 

 bates albimanus. Among other quadrumanous animals 

 peculiar to this great island, may be mentioned the 

 Semnopithecus nasicm or Proboscis Monkey, the Semn. 

 auratus and Semn. cristatus, and the Inuus nemestrinus; 

 Borneo swarms, however, with monkeys, among which 

 doubtless are many undescribed species. The Tarsius 

 or the Didelphis macrolarsus of Gmelin, is an inhabitant 

 of this island, thereby connecting it to the Fauna of 

 the Moluccas ; and Sciurus bicolor, S. niyromttatus, S.
