Geograpliical (listribiitioii of tlie Birds collected by the Expedition. 



According to its position on the bouiidary between the Indo-Chinese and the 

 Indo-Malayan Subregions, Siarn is a veiy interesting country for the study of the 

 geographical distribution of animals and in the following pages I will give some 

 tables about the distribution of the birds, found by the Expedition. 



Siarn generally belongs to the Indo-Chinese Subregion, which also embraces 

 China south of the Yangtze river, the Burmese provinces and Cambodia. But some 

 parts of the country also belong to the Indo-Malayan Subregion, which includes the 

 low lands of the Malayan Peninsula and the Indo-Malayan Islands east to the »Wal- 

 lace line», which passes through the deep sea of the strait of Lombok and is sepa- 

 rating the Australian Region from the Indian Region. 



As seen by the tables given belovv several of the Siamese birds also occur in 

 some parts of the Indian Peninsula while several also are inhabiting countries be- 

 longing to the Indian Peninsular-, the Indo-Chinese- and the Indo-Malayan Subregions,
