ZOOIyOGICAIy RESULTS OF THE ABOR 

 EXPEDITION, 19 1 1— 19 1 2. 



Introduction. 



In accordance with a resolution passed at the Conference on 

 Museums and Archaeology held at Simla in July, 191 1, it was 

 arranged by the Trustees in consultation with the Military and 

 Education Departments of the Government of India that I should 

 accompany the Abor Expeditionary Force as Zoologist and 

 Anthropologist, and that Mr R. Hodgart, Zoological Collector in 

 the Indian Museum, should go with me as assistant. 



The present volume is devoted to the zoological results and 

 parts will be issued from time to time as reports become available 

 for publication. The issue of the usual annual volume of the 

 '' Records " will continue as heretofore. 



In addition to results obtained with the Abor Expeditionary 

 Force, in several groups the determinations of animals obtained 

 by Mr. F, H. Gravely in November and December, 1911, between 

 Moulmein and the Siamese frontier will be included. The fauna of 

 this area, at least of the Thaungyin Valley, is not very dis- 

 similar from that of the Abor country, and notice of specimens 

 from this area will be of interest from a comparative point of view. 



Mr. Hodgart and I left Calcutta on November 13th and 

 arrived back on April 3rd after having spent about four months in 

 the Abor country. 



On the outward journey we were detained for about a fort- 

 night before we could proceed to Kobo, the base camp of the 

 expedition, and this period was spent in making observations on 

 the fauna at Dibrugarh on the left bank of the Brahmaputra and 

 at Sadiya which lies on the right bank at the foot of the Mishmi 

 country. 



We reached Kobo on November 29th and remained until 

 December 13th; on the 14th we left by boat-convoy up the 

 Dihang River and arrived at Pasighat and Janakmukh on the 

 evening of the i6th, and leaving the latter camp on the 19th we 

 marched to Renging and Rotung, arriving on December 21st. 



I was unfortunate in being unable to join the party which left 

 Yembung, the head- quarter camp, on December 27th to explore 

 the course of the Dihang river and survey the country to the 

 north: shortage of transport compe led Major-General Bower to 

 refuse my application. My main object when I joined the ex- 

 pedition was to explore the practically unknown Himalayan fauna
