The terrestrial mammals and birds of North East Greenland. 163 



here some 100 individuals June 9*^ & W^ 1907. It is however prob- 

 able, thai a greater number were nesting on these places. 



During the navigation from the Shetland Islands up to the pack- 

 ice a greater or smaller number of Kittiwakes appeared nearly every 

 day around the ship; but as we forced our way through the ice I 

 only now and then observed this species, generally solitary birds 

 near the edge of the ice. 



Yet I recorded 9 old birds sitting on a hummock of ice together 

 with some Sterna macrura and a larger Skua farther in the pack- 

 ice at lat. 75° 20' n. long. 8° w. August P* 1906. 



Strange to say, the Kittiwake appeared but sparsely amongst 

 the vast multitudes of sea-birds, which were seen off Jan Mayen. 



Ivory-Gull. Lams eburneiis Phipps. 



The Ivory-Gull appeared in great numbers only on one place 

 but proved however rather common as well in the pack-ice as on 

 the isles and outer-skerries lying near it. 



Some few Ivory-Gulls would as an exception pay short visits to 

 the bays and firths. 



This species was not observed more northerly than lat. 81° n. 



Though but one smaller nesting-colony was found it cannot be 

 doubted, that the Ivory-Gull nests comparatively commonly on the 

 outmost lying islands and skerries in the tract from Кар Marie Val- 

 demar to Mallemukfjeldet; here several old and young birds were 

 recorded in the breeding-season at several places. 



August 15*h 1906 I landed for a short while at Кар Marie Valde- 

 mar and observed here several old Ivory-Gulls on some islets near 

 the pack-ice. The behaviour of the Gulls made me suppose, that 

 their young ones were on the island. My stay here was very short 

 and the means of conveyance extremely difficult, therefore a nearer 

 examination was unfortunately impossible. 



Dr. Lindhard, who was left at Кар Marie Valdemar together 

 with 5 other members of the expedition, lived here and on the 

 mainland and the isles North of this point from August 16^^^ to 26*^. 

 He reports to have seen many Ivory-Gulls — as well old as quite 

 young birds — especially at Кар Marie Valdemar. 



Regarding the occurrence of this species higher North along 

 the shore, I have received the following notes from Koch and Ber- 

 telsen.
