observed on the Yenisei River. 507 



C. canorus, which is the only species I have obtained on the 

 Yenisei. 



80. *Asio oTus. Long-eared Owl. 



81. "^Asio ACciPiTRiNUs. Sliort-earcd Owh 



82. Syrnium uralense. 



Mr. Kitmanoff, the curator of the museum at Yeniseisk, 

 showed me a skin of the Ural Owl that had been recently 

 killed at the gold-mines near Yeniseisk, and also from the 

 same locality two skins ( cj" & ? ) of the following species. 



83. Syrnium lapponicum. Lapp Owl. 

 SuRNiA ULULA. Hawk-Owl. 



(Dr. Theel.) 



84. Nyctea scandiaca. 



There were many Snowy Owls sitting on the hummocks 

 on the islands in the estuary, but as we could not find a nest 

 I concluded they Avere not breeding this year, owing to the 

 scarcity of lemmings ; for where these had been runliing

 Owl, which had eaten off the head of a Brent Goose that 

 I had left by its eggs, as a mark to find them on my return. 



Bubo ignavus.

85. Circus ^eruginosus. Marsh-IIarrier. 



Circus cyaneus ? 



(Dr. Theel, in lat. 61° N.) 



86. *BUTE0 DESERTORUM. 



On my return from Yeniseisk to Krasnoyarsk I frequently 

 saw Rufous Buzzards by the roadside, sometimes perched 

 upon the telegraph-poles. 



87. ^Archibuteo lagopus. 



On landing in lat. 69° 40' N. we were not greeted by the 

 cry of Eough-legged Buzzards this year, as we were in 1895. 

 It seems that the places of those we shot two years before had 

 not been filled by others ; and the same thing applies to the
