from Nova Scotia to New York. I have not found any 

 description or figure of the egg. 



Professor Nilsson includes this species in his Fauna of 

 Scandinavia, and it is found at the Faroe Ishands. 



The substance of Faber's remarks on this species may be 

 thus given : — In size between Larus canus, the Common Gull, 

 and Larus argentatus, the Herring Gull. This is the only 

 Gull that passes the winter in Iceland without breeding there 

 in summer. It must, like Lams ehurneus^ the Ivory Gull, 

 breed in the higher northern regions, and come to Iceland in 

 winter as a bird of passage. I have travelled over most of 

 the coast of the island, but have never found its breeding- 

 place. There Avas no L. leucopterus on the rocks of Faxe 

 or Bredebugt towards the west, where L. glaucus breeds in 

 large colonies. A few days after the middle of September, 

 the first specimens, both old and young, make their appear- 

 ance on the coast of Iceland, confining themselves to the 

 northern parts among the small inlets of which great numbers 

 pass the winter. When I lived on the innermost of the 

 small fiords on the northern coast, these birds were our daily 

 guests. Towards the end of April their numbers decreased, 

 and by the end of May they had nearly all disappeared from 

 Iceland. These tame birds came on land by my winter 

 dwelling on the northern coast, to snap up the entrails thrown 

 away by the inhabitants, and fought fiercely for them with 

 the Raven. I had made one so tame that it came every 

 morning at a certain time to my door to obtain food, and 

 then flew away again. It gave me notice of its arrival by its 

 cry. This Gull indicated to the seal-shooters in the fiord 

 where they should look for the seals, by continually following 

 their track in the sea, and hovering in flocks, and with in- 

 cessant cries over them ; and whilst the seals hunted the 

 sprat and the capeling towards the surface of the water, these 

 Gulls precipitated themselves down upon the fish and snapped
