Arctic Expedition of 1900-1903. 599 



Nos. Wassili Dsergheli, who hunts for mammoth ivory every 

 year on the islands of the New Siberian Archipelago, in- 

 formed Mr. Birulia that, about thirty years previously, when 

 on the island Kovrishka (Great Liakhovski Island) he found 

 near the Eiver Kamleika, a tributary of the Bloudni, a nest 

 of Chen hyperboreus. He first saw the male bird, which flew 

 away ; he then met with and shot the female. The nest 

 contained three much-incubated esres. 



Nyctea scandiaca was met with on the Taimyr and also on 

 the New Siberian Islands. 



Otocorys alpestris was only met with on Kuskin Island, 

 where large numbers were seen. 



Anthus cervinus was not uncommon on the Waigatch and 

 on Kuskin Island, but was very rare on the Taimyr, where it 

 was only seen on two occasions. 



Saxicola oenanthe. — A young bird was seen on Kuskin 

 Island, and one was also met with on New Siberia Island, 

 but this species appears to be extremely rare on the New 

 Siberian Islands. 



Corvus corone is said to occur and to breed near 

 Verhoyansk, but Mr. Birulia records this only from hearsay 

 information. 



Corvus corax was not observed by Mr. Birulia himself. 

 Plectrophenax nivalis. — Dr. "Walter met with this bird 

 breeding commonly on the Taimyr, and Mr. Birulia believes 

 that it nests also on Kotelny Island. 



Calcarius lapponicus was found commonly and breeds on 

 the Taimyr, and Mr. Birulia remarks that the islands of the 

 New Siberian Archipelago are places very suitable for the 

 nidification of this species. 



Parus ater. — On the 5th/18th September, 1900, a single 

 bird came on board the ' Sarja,' and a second two days 

 later. On the 8th/21st September one was seen on the 

 cliflFs of the Bay of Kolomcitseff, and three days later, when 

 on an excursion on the shore of Voltchi Bay, Dr. Walter 

 and Mr. Birulia each shot an example. It is interesting chat 

 this Titmouse should have been met with so far beyond the 

 limit of the forest-region.
