Though during my journey in Siarn from the end of 1911 

 to May 1912 the greatest time was devoted to studying the 

 bird fauna about which a report has already been published 

 (Kungl. Svenska Vetenskapsakademiens Handlingar Bd. 50 

 N:r 8), I also made a small collection of mammals, and in 

 the following pages I will give a list together with some short 

 notes of the mammals collected, or observed by the Expe- 

 dition. 



The first collecting was begun in January 1912 when I 

 had my camp near the small Laos village of Sakerat in 

 Eastern Siarn. During the whole month I explored zoologi- 

 cally the environs of Sakerat and Non Luum, this last-men- 

 tioned place also a small village on the Korat plateau. This 

 part of the great Korat plateau is chiefly overgrown with 

 dry laterite forests, but here and there some great swamps 

 are also to be found. As a rule the vegetation on the 

 Korat plateau is not so thick and impenetrable as several 

 parts of Northern Siarn with its great primeval forests. 



When I had finished my researches at Sakerat I went to 

 Korat, the most important town in this part of Siarn, and 

 from there I went by rail to the North and stopped for a 

 few months at Bång Hue Horn, a place situated in the middle
