NOTE VI. 



ON A COLLECTION OF MAMMALS FROM 

 EAST-SUMATRA. 



Dr. P. A. JENTINK. 



November 1888. 



Dr. B. Hagen , the well known passionate naturalist , 

 lived several years in Tandjong-Morawa , later in Medau 

 East-Sumatra, Deli. He published in »DasAusland, 1881"

Up to the investigations made by Dr. Hagen about no- 

 thing was known concerning the Mammals of the eastern 

 part of Sumatra , and so I think that a review of his col- 

 lections will be very wellcome to naturalists, the more as 

 the Fauna of Sumatra is one of the bases upon which 

 Wallace built his wide-stretching speculations. 



Wallace (the Malay Archipelago, 1869) made inquiries 

 about the Orang-ütan (not Orang-Outang as Blanford 

 writes , see the Fauna of British India , a. s. o. , Mamma- 

 lia, Part I, 1888, p. 4), but none of the natives had 

 ever heard of such an animal , nor could he find any of 

 the Dutch officials who knew anything about it. He con- 

 cluded therefore , that it does not inhabit the great forest 

 plains in the East of Sumatra, but is probably confined 

 to a limited region in the north-west. Von Rosenberg 

 (Der Malayische Archipel, 1878) related: »der Orang-
