Mr. R. B. Sharpc on the Genus Strix. 325 



sification of the genus Strix; for his Striges auriculatoi an- 

 swer to the genus Ash. Thus the suborder Striges, as deter- 

 mined by Linnaeus and Brisson, is as follows : — 



Genus Asio^ Briss. 



1. Asio bubo (L.) ; 2. Asio scandiaca (L.) ; 3. Asia asio 



(L.) ; 4. Asio otus (L.) {Asio, Briss.) ; 5. Asio scops (L.). 



Genus Strix, Linn, (partim). 



In this would come all the Owls mentioned above, viz. 

 Nos. 6. to 12. 



Beyond the pubhcation of numerous other species by Sco- 

 poli, Latham, Gmelin, and others, no additions to the generic 

 nomenclature of the Owls appear to have been made till 1799, 

 when Cuvier, in his ' Le9ons d^ Anatomic comparee ^ (table ii.), 

 divid(;d them into Hibous {Otus) and Chouettes {Strix). 

 No types are indicated ; and it is evident that this is a revival 

 of the old Brissonian arrangement, so that Otus of Cuvier 

 is merely a synonym of Asio of Brisson. 



In 1806 Dumeril published his ' Zoologie Analytique •/ and 

 here the arrangement is affected by the removal of the Hawk 

 Owls (Nos. 10, 11, Linn.) to the genus Surnia. His genus 

 Bubo, of which he is so often quoted as the proposer, is a 

 nominal one only, and is said by him to contain the Horned 

 Owls of Linnaeus. Thus Bubo of J)\xviie,x'A^= Asio of Brisson. 

 Before considering the revolution worked by Savigny, it may 

 be well to set down the exact state of the classification of 

 Owls after DumeriFs modification : — 



1. Asio, Briss. {Otus, Cuv. j Bubo, Dura.) 



1. A, bubo (L.) ; 2. A. scandiaca (L.) ; 3. A. asio (L.) ; 

 4. A. otus (L.) ; 5. A. scops (L.). 



2. Strix, Linn. {Sti'ix, Briss., Cuv.) 



6. S, nyctea, L. ; 7. S. aluco (L. : stridula, L.) ; 8. S.jlam- 

 mea, L. ; 9. *S^. passerina. 



3. SuRNiA, Dumeril. 

 10. /8. idula (L.) ; 11. S.funerea (L.).
