I. — On the Raptorial Birds of the Malay Archipelago. 

 By Alfred R. Wallace, F.Z.S. &c. 



(Plate I.) 



In the ' Museum d'Histoire Naturelle des Pays-Bas/ the pub- 

 lication of which was commenced in 1862, Professor Schlegel 

 has given a complete enumeration, often accompanied by de- 

 scriptions and measurements, of all the specimens of Rap- 

 torial Birds contained in the Leyden Museum ; and in his more 

 recent work, ' Les Oiseaux des Indes Neerlandaises,' the third 

 monograph"^, published in 1866, contains figures and descrip- 

 tions of all the Falco7iida known to inhabit the Dutch East- 

 Indian possessions. Later still, in the * Proceedings of the 

 Zoological Society of London' for 1867, is a paper by Dr. 

 Kaup, " On the Nisi and Astures of the Indian Archipelago and 

 of New Holland,'' undoubtedly the most difl&cult group of the 

 Eastern Accipitres. It may fairly be asked, therefore, what 

 novelty or interest the present Catalogue possesses, to render it 

 worthy of publication in ' The Ibis.' 



My answer is, that Professor Schlegel's works above enume- 

 rated do not give a complete list of the Malayan Accipitres ; for 

 the first is a Museum Catalogue, the second a Colonial fauna ;
