— il occurred frequently, though not in great numbers, the next 

 summer. 



The Black Guillemots especially stayed near the little rocky 

 island Maroussia in the field-ice. Here several spots became free 

 from ice earl}^ in the season, and the low steep rocks of the island 

 afforded favored nesting localities. 



When I visited the island July 18*'^ 1908, I saw 5 to 6 breeding 

 females, and some old birds in full plumage lying in the water in 

 the neighbourhood. 



F^ven in the ship's-harbour, quite near the coast, some Black 

 Guillemots appeared this summer and swam fearlessly around the ship. 



Old birds as well as j^ung were observed here. 



Koch's north-going sledge-party met in the summer 1907 — just 

 olf Mallemukfjeldet (lat. 80°10'n.) — with a great deal of open water 

 in which 3 Black Guillemots w^ere observed June 10*^\ 



July 1908, during the homeward navigation through the pack- 

 ice, I observed several times solitary Black Guillemots (as far North 

 as 78°), all old birds in full plumage. In the stomachs of the few 

 birds I secured for examination, I principally found remnants of 

 crustaceans and in a single case Chœiopoda. 



For the zoological museum in Copenhagen were collected the 

 skins of two young birds (the wing spot mottled) and in spirit an 

 old female in full plumage. The following measures have been 

 taken :

As the ship on its voyage to Greenland passed Jan Mayen (July 

 28'ii 1906; about 70 km. east of the island) these Guillemots appeared 

 in extremely great numbers. The birds occurred solitary, in couples 

 and in smaller flocks, and were so fearless, that they flying or 

 swimming often came within a distance of but 3 to 4 meters. 



No Guillemots were seen while Ave sailed through the ice, and 

 during the expedition's stay in the country only two males were 

 recorded; they were swimming in Danmarks Havn and were at 

 last shot near the ship (July 13*^ 1908).
