Birds of the Yenisei River. 455 



85 a. Circus cyaneus (Linn.). 



The bright-coloured birds of prey that we so frequently 

 saw in the neighbourhood of Ycinseisk were, I believe, Hen- 

 Harriers, though we were never able to make certain of their 

 identity by sliooting one. 



89. AcciPiTER Nisus (Linn.). 



The Sparrow-Hawk occurs at Yeniseisk. 



96a. Pandion haliaetus (Linn.). 



Ospreys were occasionally observed in suitable localities 

 round Yeniseisk. 



97 a. CicoNiA NIGRA (Liuu.). 



A single Black Stoi'k was seen at Yeniseisk. 



99 a. Anser erythropus (Linn.), 



I shot a veritable Lesser White-fronted Goose on the 

 Fokina River (hit. 68° 30' N.) ; it weighed only 4^ lbs., or 

 very little heavier than a Brent Goose, and had conspicuous 

 bright yellow eyelids. In about lat. 69° 30' N. a man brought 

 on boai'd for sale 38 geese, selected from some 200 that 

 he and others had captured during the raoulting-season ; 

 the birds had been plucked, but the heads were intact, s:) 

 that we could see that the majority were Bean-Geese, with 

 a few White-fronted Geese (Anser albifrojis) ; among the 

 latter we were easily able to pick out two of the Lesser 

 variety, from their smaller size and comparatively smaller 

 heads with shorter bills, as well as fi'om the yellow eyelids. 

 They had a considerable amount of white on the forehead 

 extending well up between the eyes. 



101. "^Bernicla. ruficollis (Pall.). 



The valleys where the Red-breasted Geese bred in 1895 

 were still full of snow when we visited them on July 2nd, 

 1900, and though we saw some of the birds in various places 

 we found no nests. 



102 a. Tadorna cornuta (Gmel.). 



We did not ourselves observe this Sheldrake, but were 

 shown one in the flesh that had been killed by a local gunner
