„^gv8er"-proprietor. This hungry marauder wages endless war 

 with all other sea-fowl. The Terns, however, (Sterna fluviatilis 

 and Jiirundo), and Larus camis fiercely repel its predatory attacks, 

 and even Strepsilas interxjres will muster up courage for a fight, 

 should it venture to encroach upon its territory. 



When three or four individuals of this species encounter one 

 another in the breeding-season, they will often perform a series of 

 graceful evolutions, one bird swiftly circling round the other, and 

 uttering as they descend with pendent unmoved wings, their harsh, 

 stridulous, and snuffling cry: eau, eau. 



Lestris cepphus, Briinn. (Buffonii, Boie). 



In the province of Finmark, this species is most common in 

 the interior tracts of East Finmark. It has been found breeding 

 up to Karasjok and Kautokeino, and probably frequents each of 

 the extensive marshes in that locality. 



A sm'all colony is resident in the mosses of the Dovre, (Op- 

 dalj, preying principally on Myodes lemmus. 



Fulmar us glacialis, Lin. 



Frequents even in summer almost every locality on the coast, 

 and the islands forming the outermost „SkJ8ergaard", and is regu- 

 larly observed off Fugl0 by vessels leaving the port of Troms0. 

 On some of the fishing-grounds, at Storeggen for instance, off Aale- 

 sund, they sometimes occur in dense flocks, large numbers being 

 occasionally caught from the decks of vessels with baited fish-hooks. 

 These summer individuals are probably all immature birds. 



This species is not common on the shores of the south, visi- 

 ting only the extremities of the fjords: but two individuals have 

 been shot in the Christiania Fjord, the last early in January 1872. 



Procellaria pelagica, Lin. 

 Its occurrence north of Lofoten (69°) has not been sufficiently 

 authenticated. Mr. Barth thinks he observed a small flock off the 

 coast of East Finmark, but the species has not been found there by 

 other naturalists.
