1096 LIST OF WESTERN AUSTRALIAN BIRDS, 



64. Threskiornis strictipennis, Gould. 



65. ARDEA NOViE-HOLLANDljE, Lath. 



66. Tadorna rad j ah, Gamot. 

 None of these differ from eastern individuals of the same species. 



Part II. 

 Mr. T. H. Boyer-Bower's Collection. 



In addition to the 66 species just enumerated, I have been per- 

 mitted to examine a fine collection made by T. H. Boyer-Bower, Esq., 

 in the viciDity of Derby. All the specimens were obtained within 

 twenty-five miles of the coast, and although this collection contains 

 a larger number of species than that made by Mr. Cairn, we miss 

 the rare forms apparently characteristic of the interior. This 

 want is somewhat compensated by the additional species which we 

 are enabled to enumerate. 



67. Circus assimilis, Jard. & Selb. 



{Circus Jardinii, Gould, Birds of Aust. fol. Vol. I. pi. 27.) 

 A very highly coloured individual in full plumage. 



68. Haliastur sphenurus, Vieill. 

 69. Milvus affinis, Gould. 



70. Falco lunulatus, Lath. 

 71. Tinnunculus cenchroides, Vig. & Ilorsf. 



(1. bis) Astur approximans, Vig. & Ilorsf. 



Mr. Boyer-Bower's collection contained a large series of this last- 

 named species in different stages of plumage, none of which, how- 

 ever, can be considered identical with Gould's Astur cruentus.
