Mr. li. B. Sliarpe un the Gtnus Strix. 327 



when Cuvier published the first edition of the 'Regne Animal;' 

 for there he distinctly separates the genera Bubo and Otus, 

 reserving to the former the Great Horned Owl [Strix bubo) 

 as its type. His genns Otus contains both the Bubones of 

 Savigny's work. 



In 1822 Fleming {' Philosophy of Zoology/ ii. p. 236) sepa- 

 rates the Barn-OAvl off as Aluco ; but this species having been 

 defined by Savigny as the type of Strix, the genus Aluco is 

 but a synonym of the latter. 



The year 1826 brings the last modifications of the Linneean 

 Owls, when Stephens proposed the genus Nyctea for the 

 Snowy Owl {Strix nyctea, Linn.), to which, as recently de- 

 monstrated by Professor Newton, is also referable Linnseus's 

 name oi scandiaca. The genus Asio is therefore left with 

 the Long-eared Owl, Asio otus (L.), which consequently be- 

 comes its t}']pe, while the sole unappropriated survivor of the 

 genus Strix, viz. ;S^. passer i?ia, is in this same year seized by 

 Boie and made the type of his genus Glaucidiurn. A final 

 revision of the Linnsean genus Strix, in the year 1826, gives 

 the following distribution of his species : — 



1. Asio, Briss. 1760. 

 1. Asio otus (L.). 



2. Strix, Linn. 1766. 

 1. Strix flammea, L. 



3. SuRNiA, Dum. 1806. 



1. Surnia ulula (L.) ; 2. Surnia funerea (L.). 



4. Scops, Savign. 1809. 



1. Scops giu (Scop.) [ = Strix scops , L.) ; 2. Scops asio (L.). 



5. Syrnium, Savign. 1809. 

 1. Syrnium aluco (L.) {Strix aluco, L., et Strix stridula, L.) . 



6. Bubo, Cuvier, 1817. 

 1. Bubo ignavus, Forst. {Strix bubo, L.).
