 BY MR. CAIRN, AND MR. W. H. BOYER-BOWER, 

 AT DERBY AND ITS VICINITY, WITH REMARKS 

 ON THE SPECIES.

Part I. 



Mr. Cairn's Collection. 



The Australian Museum has recently become enriched by a fine 

 collection of Birds from Western Australia, obtained at Derby 

 and its vicinity by Mr. Cairn, who, it will be remembed, made some 

 important zoological collections during 1882-3 in New Guinea. 



The following is a list of the species which have already come to 

 hand, for, unfortunately, two boxes containing a large portion of the 

 collection are still missing. 



1. Astur approximans, Vig. & Horsf. 



Although Gould has given the name of Astur cruentus to the 

 western species I have not yet seen any specimens that can be 

 distinguished from the birds known to us from Eastern Australia. 



Salvadori (Orn. Pap. et Molucc. I. p. 60), places Gould's A. 

 cruentus with Cuvier's Falco (Urospizias) torquatus, and my 

 Astur sharpei and others ; but in this I cannot concur. 



Gould's A. cruentus, may be the same as the Timor bird, but it 

 is certainly not identical with A. sliarpei. The figures of A. 

 approximans, given by Gould, (fol. Yol. I. pi. 17), have been 

 taken from immature birds ; when fullv adult the bars in the 

 under surface of the body are of a rich vinous red. Younger 

 specimens closely resemble Accipiter torquatus in plumage (p. 1096).
