The present notes are based upon a collection of Ma mm als made in Eastern and 

 Central Borneo 1914 — 1915 by the well-known Norwegian explorer Mr. Carl 

 Lumholtz. 



The collection was sent by Lumholtz to the Zoological Museum at Christiania, 

 and through the courtesy of its former Director Professor Dr. Theodor Odhner 

 the Mammal skins were forwarded to the present author for examination and deter- 

 mination. 



Mr. Lumholtz who still is in America has kindly sent me the following notes 

 about the geographical position of the localities where specimens of Mammals have 

 been obtained. 



Mr. Lumholtz vvrites as follovvs: 



»Kaboerau is a Dyak kampong on the Kayan or Boelongean river, on the 

 East coast of Dutch Borneo, at about Lat. N. 3°. It is about two days travel 

 (paddling) by boat up stream from Tandjong Selor. 



Mandurao is a creek, half a days journey further west. From here I struck 

 inland through the jungle perhaps 16 miles nortwards, camped for some time on 

 the top of a hill, which I called Camp Gunong (or camp 6), about 2,000 feet above 

 sea-level. A few miles further north is another hill, 2,622 feet above the sea, on 

 the top of which Camp 7 was established. 



Camps 3, 4 and 5 are situated between Camp 6 and the river. 



Long Pangian is a small Malay and Chinese settlement two or three days 

 travel by boat further west. 



Long Palabar is a kampong two days further west from Long Pangian and 

 on the same or Kahayan river. 



Pipoh is a small tributary, half a day further west. The country along this 

 river is quite uninhabited. 



Poeroeok Tjahoe is a small Malay and Chinese town in Central Borneo at the 

 Barito river. 



Toembang Maroeive is a D} ; ak kampong a couple of days journey east of Poe- 

 roeok Tjahoe.» 



The bulk of the collection has been obtained in a District of Dutch East 

 Borneo called Boelongean. This District has derived its name from the Boelongean
