The Red -throated Diver is found commonly in the fjords 

 and fresh water lakes. It is more frequently seen than Co- 

 lymbus glacialis, and seems like this species to be specially 

 fond of the mouths of big mountain streams, where I suppose 

 the fishing is most profitable. 



Downy young ones were seen July 25*'* in a little lagoon at 

 the mouth of Turner Sund.

The great Northern Diver seems to be more frequent in 

 the fjords than at the outer coast-line. 



Fulmarus glacialis (L.|. 



While the expedition was staying outside the East-coast of 

 Greenland the Fulmar was seen every day, in the floating ice 

 around Jan Mayen, in the North- Atlantic and in the northern 

 part of the North-Sea. — It occurs in greatest numbers around 

 the nesting place Jan Mayen, but it is also numerous in the 

 vicinity of the floating ice -belt and in the outskirts of same. 

 Farther into the ice -belt the bird becomes rarer, and at the 

 coast it is only seen singly, still frequently enough so that 

 hardly a day — as said before — passes without its being 

 seen a couple of miles off land. It never goes very far into 

 the fjords. 



According to my observations the grey race seemed to 

 become more numerous the farther west and into the ice the 

 expedition came, and most strikingly so west of Jan Mayen. 

 Of twenty specimens shot July 7*^, thirteen were grey. Seventeen 

 of these were closely examined and opened; sixteen proved to
