DISTRIBUTION OF MONKEYS AND LEMURS 223 



ferocity of the Gorilla are based on fact seems to be still 

 quite doubtful. The few specimens of this animal that 

 have reached Europe alive have not given much support 

 to the stories told about it. 



The genus Anthropopithecus, therefore, with its two, or 

 perhaps three, species, may be regarded as one of the most 

 characteristic forms of the mammal-life of the Ethiopian 

 Region to which it is absolutely confined. 



Passing on to the next genus of Anthropoid Apes, we 

 find that the Orangs {Simia) are in like manner one 

 of the most characteristic mammal-forms of the Indian 

 Region, to which they exclusively belong. As in the case 

 of the Chimpanzee, there has been the same difference of 

 opinion among naturalists as to whether there is only 

 one or several species of Orangs. The Orang is found 

 only in the dense forests of Borneo and Sumatra. The 

 forms met with in these islands respectively have been 

 treated as specifically distinct, and the Bornean form has 

 also been divided into several species. But, on the whole, 

 the prevalent opinion of modern writers is that there is 

 only one variable species of Orang, which we call by Lin- 

 naeus' name Simia satyrus. In Sumatra this Ape is mainly 

 found in the lowlands of the eastern coasts of the island, 

 in the districts of Palembang and Jambe. In Borneo it 

 is more numerous, and has a wider range, extending all 

 over the low forest-covered swamps between the coasts 

 and the mountains of the interior, but in some places 

 ascending to a considerable height in the lower hills. 



The third and only remaining genus of Anthropoid 

 Apes contains the Gibbons, or Long-armed Apes (Hylobates), 

 which are likewise restricted to the Oriental Region, but 

 have a much wider distribution than the Orang. The
