of Scotland, and a few occasionally stray as far southward as 

 the Northumbrian coast, where I have obtained three or 

 four specimens, but all in the immature plumage. Its habits 

 are stated by Mr EDMONSTON to be more lively and active 

 than those of the Glaucous Gull, and it displays more ele- 

 gance of form. It is a common species in the Arctic Regions, 

 and is mentioned by SABINE and RICHARDSON as being plen- 

 tiful in Baffin's Bay, Davis Straits, and Melville Island. It 

 is also common upon the Iceland coast, to which it is pro- 

 bable many of those that winter with us, and in similar lati- 

 tudes, retire to breed. It feeds upon fish, the flesh of whales, Food - 

 and other carrion, and when upon our shores, is sometimes 

 seen in company with the Black-backed Gull.
