of a Zoological Collection made in Sumatra, 241 



Part I. MAMMALIA. 



SIMIA. 



Of this genus nine or ten species are known to the natives of 

 these islands, the greater part of which are in the collection. 

 The first is the well known 



SIMIA Satyrus Linn. 

 Orang Utan of the Malays, ^y, cJ 



Of this a living specimen from Borneo was sent to the Mena- 

 gerie at Calcutta in 1819. Native information gives reason to 

 believe that it also exists in Sumatra ; it is there known by the 

 name of Orang Pandak (Pygmy), and the accounts given of it 

 agree exactly with the Orang Utan of Borneo- It is frequently 

 confounded with the Orang Kubu and Orang Gugu described by 

 Mr. Marsden, which, though often the subject of fable and exag- 

 geration, appear to exist on the island as a distinct race of men, 

 almost as hairy and wild as the real Orang Utan. 



The observation of Linnaeus, that the nail of the thumb is 

 wanting on the hind-feet, is confirmed by the above specimen, 

 and is probably correct in all the true Orang Utans. 



SIMIA SYNDACTYIA.

This new species of Gibbon is abundant in the forests near 

 Bencoolen, where they are seen in large companies, making the 

 woods echo with their loud and peculiar cry. 



It is of a jet-black colour throughout ; is upwards of three feet 



in height, and of a robust and muscular frame. It agrees with
