Ornithology of Borneo. 235 



Oxford University Museum to prepare an account of a very 

 large consignment of birds presented to that institution by 

 Mr. W. H. Treacher, the present Acting Governor of La- 

 buan. Four large cases made up the latter^s collection ; and, 

 as in the case of that of Governor Ussher, every specimen 

 had the exact locality recorded ; so that we may now feel 

 certain that we have a very fair representation of the avi- 

 fauna of North-western Borneo. 



Mr. Treacher, after Governor Ussher's return to England, 

 obtained a great many birds from the Lawas river, as well 

 as from Lumbidan and from Brunei, together with a small 

 collection from tlie neighbourhood of Kina Balu. This last 

 I have deemed of sufficient importance to be the subject of a 

 separate paper. Mr. Burbidge has also submitted to me a few 

 birds from the Lawas river, which are likewise here noticed.

Brunei [coll. Ussher). 



The collections sent by Governor Ussher contained both 

 adult and young birds of this Harrier ; and on comparing the 

 young birds obtained by him with those collected by Mr. 

 Alfred Everett at Sibu icf. Sharpe, I.e.), it is evident that 

 the latter were properly identified by me, and that C. arugi- 

 nosus does not visit the Malay archipelago.
