LIST OF BIRDS COLLECTED AT DERBY, NORTH WEST 

 AUSTRALIA, BY THE LATE T. H. BOYER-BOWER, 

 Esq., with NOTES. 



By Dr. E. P. Ramsay, F.R.S.E., &c., &c. 



(Continued from Vol. I. (2nd ser.) p. 1100.) 



1. Gypoictinia melanosternon, Gould. 



One specimen similar to the eastern form of this species. 



2. Falco lunulatus, Latham. 



(Falco /rontattcs, Gould). 



One specimen is a rich slate-blue on the upper surface, and 

 below has a deeper orange rufous tint than I have observed in 

 any of the N.S. Wales examples. 



3. Circus assimilis, Jard. & Selb. 

 (Circus jardinii, Gould). 



4. Circus gouldii, Honp. 

 (Circus assimilis, Gould). 



5. AsTUR approximans, Vi(/. & Sots/. 

 Quite similar to the N. S. Wales examples. 



6. AsTUR CRUENTUS, Gould. 



These are the fii'st examples I have seen of this species, which 

 is undoubtedly a very distinct form from A. approximans; in 

 plumage it closely resembles Accipiter cirrhocephalus. 



Total length male 13-5 in., wing 9-3 in., tail 7 in., tarsus 2-7 in. ; 

 first joint of mid-toe 0-55 in. Female 15-5 in., wing 10 in., tail 

 8-5 in., tarsus 2*9 in. ; first joint of mid-toe 0*7 in.
