siderable distance inland. The laughing gull (L. atri- 

 cilla) is very seldom seen in this country. 



The ivory gull (L. eburneus). The home of this 

 species is in Greenland and Spitzbergen, whence it oc- 

 casionally visits the west coast of Finmark and Nord- 

 land, in Norway. It also occasionally visits the vici- 

 nity of Bergen and Throndjem. It feeds on fish, alive 

 and dead \ and when pressed by hunger, it will eat fish 

 in a putrid state. Its Norwegian name is hvid-maage, 

 or white gull. 



The kittiwake (L. tridactylus) . During the summer

 Keilhau says it breeds on the coast of Finmark. The 

 nest is made on low rocks, and contains three eggs of 

 a pale olive colour, marked with gray and brown spots. 

 Nilsson says that the young are fully fledged by the 

 beginning of July. 



The common gull (L. canus). Common on all the 

 Norwegian coasts, and is frequently seen inland, in-

 fislt-maage, or fish-gull. Nilsson speaks of a variety
