30 BIRDS AND MAMMALS OF EAST SIBERIA [^' vbf.' V*^' 



in less numbers east to Cape Chelakhskai, beyond which point it 

 was not seen. 



It arrived at Nijni Kolymsk in the spring on the astonishingly 

 early date of May 10. It did not breed in the low-lying islands of 

 the Delta of the Kolyma, used by the white-fronted goose, but 

 seemed to prefer high, dry tundra. A nest containing two eggs, 

 that were hatching, was found at Cape Bolshaja Baranov, July 6, 

 1912. The eggs were put beside the stove on board the schooner, 

 and next day the young birds came out from them. 



Large flocks of the Eastern bean goose were seen at Nijni Kolymsk 

 as late in autumn as September 20. 



Branta nigricans (Lawr.). 



The black brant is not common on the Siberian Arctic coast. 

 A pair were observed at Insoune Lagoon, fifteen miles west of East 

 Cape, Oct. 7, 1912, and a nest was found in a valley thirty miles 

 east of Cape Bolshaja Baranov, July 12, 1912. This contained 

 five downy young, just hatched, one of which was not yet free from 

 the egg-shell. The nest was in a tiny, grassy islet in a tundra lake. 

 The young and both parents were secured and preserved as 

 skins. 



Philacte canagica (Sevastianoff). 



The emperor goose was rare, but occasionally was seen along the 

 Arctic coast of Siberia. Beyond Koliutschin Bay it became rarer 

 still. 



Cygnus cygnus (Linn.). 



Several times during the season Mr. Koren saw large swans 

 in the Kolyma River, that he feels sure belonged to this species.
