THE SIBERIAN COAST (AUTU MN 1893). 



Flectrophenanc nivalis, (Lin.) 1766. 

 Observed everywhere along the North Siberian coast where a landing 

 was made, up to Taimur Island, and on the west side of Cape Chelyuskin. 

 The birds were seen, as a rule, only singly or a few together. 



Falco aesalon, Tunst. 1771. 



At the eastern end of Yugor Strait, on July .30th, on the little island 

 Sakolii (or Falcon Island), a couple of these birds were seen, which evidently 

 had young ones, for they darted down with wild screams, almost at Nansen's 

 head. The island was a rocky one, with a precipitous cliff on the north 

 side, near which these birds had their home. 



On Reno [1¥ 46' N. Lat, 85" 42' E. Long.), on August 21st, another 

 falcon was seen from the ship, but on account of the distance, it could not 

 be determined. 



?Archihuteo lagopus, (Gmel.) 1788. 

 On Sakolii Island (at the eastern end of Yugor Strait), on July 30th, 

 almost simultaneously with the preceding, a large bird of prey was observed 

 circling at a considerable height. As the wings were rounded, it probably 

 belonged to the above species. 



JSyctea scandiaca, (Lin.) 1766. 

 Both at Khabarova and all through Yugor Strait, this species was 

 numerous in the autumn of 1893; and near the eastern end of the strait
