meets with the Siberian Great Horued Owl, Ust-Urt, Russian 

 and Eastern Turkestan, and the Pamir. Skins of jB. turcomanus 

 obtained near Irkutsk and Kultuk were received by us from 

 the late Mr. Shvedov. It is probably the same species of 

 Great Horned Owl which inhabits Tibet and the highlands 

 of Persia. 



The north-western limit of the breeding-range of Bubo 

 turcomanus , between the Lower Volga and Upper Ural, is 

 still unknown. Probably the ranges of the two species 

 overlap in that country. 



Scops giu. 



The Scops Owl is commonly distributed in South-eastern 

 Russia ; it is rare in the southern and south-western portions 

 and is very local in the central governments. 



It breeds commonly in the forests of the Southern Ural, 

 and in the outlying spurs between the Sakmara and Tandyk 

 rivers ; it is not uncommon in the forests near the Ural 

 river and the Lower Volga, but is very rare near Astrakhan, 

 where it is said to be a resident. 



We do not know any thing of its distribution in the 

 Governments of Ekaterinoslav and Kherson, nor of its breed 

 ing-range in the Governments of Kursk, Chernigov, and 

 Smolensk ; but it is a very common resident in the 

 Crimea, and it breeds in Bessarabia, the Government of 

 Kiev, the Government of Orel, the southern portion of 

 the Government of Tula, and probably in the district 

 of Laraisk in the Government of Riazan. According to 

 Mr. Taczanowsky it is a rare resident in Poland and Li- 

 thuania. 



During migration this bird is very common near Guriev 

 (at the mouth of the Ural river).
