124 PROCEEDINGS OP THE ACADEMY OF [1890. 



CATALOGUE OF THE OWLS IN THE COLLECTION OF THE 

 ACADEMY OF NATURAL SCIENCES OF PHILADELPHIA. 



BY WITHER STONE. 



In the following list I have not followed Mr. Sharpe's Catalogue 

 of Birds in the arrangement of the genera and species as was done 

 in the Catalogue of the Muscicapidre (Proc. Phila. Acad. 1889, p. 

 146), since his work seems to differ in this respect from most of the 

 recent works on the subject. But, having adopted the names and 

 arrangement of the North American species, as given in the A. 0. U. 

 Check List, I have endeavored to interpolate the foreign genera 

 and species in their proper places, and to make the nomenclature 

 conform, as nearly as possible, to the code of the American Orni- 

 thologists' Union. 



The total number of species and subspecies of Striges seems to be 

 somewhat over 200 and of these the Academy collection contains 

 113, represented by 525 specimens including the types of 14 species. 

 The principal individual collections to which the specimens be- 

 long are as follows : 



Massena collection, covering the whole world. 



Gould collection, Australia. 



Boys collection, India. 



DuChaillu collection. West Africa. 



Prince Momfanoi collection, Siam. 



Pease and D'Oca collections, Mexico. 



Townsend collection. Western N. A. and Sandwich Islands. 



Cassin and Krider collections, mainly N. A. 



Abbott collection of skins, North America and West Indies. 

 The majority of these were contained in the private collection of 

 Dr. Thomas B. Wilson and w'ere presented by him to the Academy. 

 After each species are given the localities from which the Academy
