io8 NATURAL SCIENCE. Aug.. 1893. 



natural sub-region seems to be the Himalo-Malayan Sub-Region, 

 which includes the high mountains of Burma, the Malayan Penin- 

 sula, Sumatra, Java, and Borneo. A representative form would be 

 Psarisomus. The Indian Region would, therefore, be divided as 

 follows : — 



1. Indian Peninsular Sub-Region. 



2. Indo-Malayan Sub-Region. 



3. Indo-Chinese Sub-Region. 



4. Himalo-Malayan Sub-Region. 



5. Himalo-Chinese Sub-Region. The high mountain portion 



of the Indo-Chinese Sub-Region. 

 In the Australian Region, east of Wallace's line, I think that the 

 following sub-regions can be fairly well recognised : — 

 I. Celebean Sub-Region. 

 II. Moluccan Sub-Region. 



III. Papuan Sub-Region, which should include North Eastern 



Australia with its Casuarius and Tanysiptera. 



IV. Australian Sub-Region. 

 V. New Zealand Sub-Region. 



VI. Fijian Sub-Region. 

 VII. Hawaiian Sub-Region.
