being barred with deep tawny and brown in about equal proportions, 

 as in JJ. ir/mtvits, in B. turcomanus these feathers are orange-buff, nar- 

 rowly crossed with about eight bars of brown. The same differences 

 are seen m the wing, the prevailing colour being orange-buff in the 

 quill-iining of 5. turcomanm ; in the under wing-coverts there is also 

 a ditterence, these being barred across in B. ignavm like the breast, 

 whereas in the Siberian Owl they are nearly uniform. The dif- 

 terences in the upper surface of the two birds chiefly consist in the 

 entirely paler colour of B. turcomam>s, the tawny buff colour predo- 

 minating. '■
