observed in the Kola Peninsula. 491 



VVe observed neither this nor the preceding species in Kan- 

 dalax Bay, but Pleske records both from there. 



Larus glaucus. 



We saw two or three of these Gulls in Kandalax Bay on 

 July 4th and 5th. We also observed a few of them among 

 the ice in the White Sea near the mouth of the Ponoi river, 

 on the east coast of Russian Lapland. 



KiSSA TRIDACTYLA. 



The Kittiwake was fairly common in the Kola Fjord. 



Stercorarius crepidatus. 



A few Arctic Skuas were seen near Ekaterina. At Vardo 

 on June 16th a pair (light male, sooty female), which had eggs 

 on a bare patch of ground surrounded by deep snow, were 

 accompanied by a dark bird at which they were continually 

 swooping, as though with the intention of driving it away. 

 We were unable to shoot this third bird, but at Ekaterina 

 on August 3rd we found two pairs of light-coloured birds, 

 each accompanied by a third dark bird, which was treated 

 in the same way as the one at Vardo. On one of these 

 dark birds being shot, it was found to be an immature bird 

 of apparently the year before, since it still retained several 

 rufous-edged feathers, had a barred breast and a pointed 

 tail. Is it possible that pairs of Arctic Skuas are sometimes 

 accompanied during the breeding-season by a young one of 

 the year before ? On the other hand, we found near Ekaterina 

 three birds of the year together unaccompanied by any adult 

 bird. 



Stercorarius parasiticus. 



A pair of Long-tailed Skuas, shot near Ekaterina, were 

 the only ones seen. The stomach of one contained a mouse ; 

 that of the other held seeds, probably those of the crowberry. 



Uria grylle. 



Black Guillemots were common in Kandalax Bay and at 

 the mouth of the Kola Fjord. 



COLY'MBUS GLACIALIS. 



On a small lake in a marsh near the Imandra, which we
