Obs. Pallas (op. cit., p. 356) is mistaken in calling it in Bashkir 

 £ak targe, as this name belongs to Nydale. According to a 

 Zirian from Ijma, Circus aeruginosus occurs on the Volga, and 

 is called there Outka-varesh* 



if Ma barbata, Pall. I never saw this bird here, but according to 

 Martin it was found by him about 30 versts from the Poleff works. 

 According to Mejakoff (I.e.) it breeds in the Vologda Govern- 

 ment, and according to Nordmann {I.e.) it occurs in the southern 

 parts of Finland. 



Ulula uralensis, (Pall.) Is very common in all the fir woods 

 throughout the Perm Government, and does not appear to breed 

 in any other forests. In Perm it is called Baba ; in Ekaterin- 

 burg, Maleyfilui; Bashk., Tall-uhu; Ziridn, Eud-pelui. 



Ulula ahico, (L.) Is not so common as U. uralensis, and is rather 

 rarer on the eastern declivity than in Central Russia. It does not, 

 I think, occur in the northern parts of the Perm Government. 

 Ziridn, Serapelui 



AEgolius ohis, (L). Is extremely abundant on the eastern slope 

 of the Ural mountains, and probably ranges as far north as 59° 

 N. lat. Russ., Seek. 



AEgolius brachyotus, (Forster). Is met with in the more open 

 plains, consequently mostly in the southern parts of the Govern- 

 ment of Perm. I never saw it north of 58° N. lat. (Tagill), 

 although Middendorff found it much further north on the 

 Boganida (Sib. Reise, B. 2, Th. 2, p. 130), and at Udsky Ostrog, 

 and Nordmann {he.) traced it as far as the White Sea. 



Nydale tengmalmi, (Gmel.) Has not been found further north 

 than the Pavdinskay Dacha, 59° N. lat. Thence southwards it 

 becomes more common, but is nowhere so numerous as AEgolius 

 otus. Russ., Sechik; Bashk., BuUarge; Meschersk, Baigosh; Ziridn, 

 Vorobay-varesh. 



Surnia passerina, (L.)t Is found, but is scarcer than the preceding 

 species, and its limits of distribution are not known exactly. 



Surnia funerea, Auct. Is very common, but has not been traced 

 very far north. It appears to be most numerous on the eastern 

 slope of the Ekaterinburg Ural. 



Surnia nydea, (L.) Throughout the Perm Government, being
