Rt-ad 7th May, 1914. 



^^ 1 HE experience of the Exjiedition sent by the British Ornithologists' Lcioii in 



1910-11 to New Guinea proved that it Avas not possible to reach the central rangi 

 ^ Snow Mountains (Nassau Range) by way of the Mimika River. It appeared tha 

 23 Utakwa Uiver, about 50 miles to the east, offered a better prospect of success, and JVii. 



E. R. Wollaston, who. had been a member of the first expedition, proposed to conduct 



; another and to enter the country by that river. The Committee of the British 



Ornithologists' Union Expedition genei'ously handed over to him the balance of their 



^ fund, and through the generosity of certain subscribers he was enabled to return in 



V 1912. The object of this second expedition, which was organised and conducted by 



Mr. Wollaston, was to collect animals and plants, study the ethnology of the natives and 



explore, so far as possible, the geography of the part of the Nassau range drained by the 



Utakwa River. Mr. Wollaston was fortunate in securing the services of Mr. C. Boden 



Kloss, Assistant Director of the Museum at Kuala Lumpur, Federated Malay States, ibr 



the supervision of the zoological and botanical collections and the photographic work. 



The transport work was carried out by 71 Dyaks from Borneo, whilst five collectors, 



natives of SaraAvak, were employed in collecting botanical specimens. The party was 



accompanied by an escort provided by the Netherlands East Indian Government, under
