north as Buchanan Strait (lat. 79°); hut this bird was not seen 
again by me until our return southward in September 1876, 
after regaining navigable water south of Cape Sabine. The 
north water of Baffin Bay is evidently the limit of the north¬ 
ern range of the species in that direction; and I doubt if 
there are any breeding-haunts of this species north of Cape 
Alexander. 
20. Colymbus-—. 
On the 2nd September, 1875, at Floeberg Beach (lat. 82° 
27' N.), a Diver, I think C. septentrionulis, alighted in a pool 
about a hundred yards from the ship. A boat was instantly 
lowered ; but the noise made by pushing the boat through the 
young ice alarmed the bird, which rose and flew to another 
pool half a mile to the southward. I tried to make my way 
over the floe towards the bird ; but the ice was unsafe, so I had 
to give up the pursuit. The numerous lakes and ponds in 
Grinnell Land abound with a species of char (Salmo arcturus, 
Gunther), which doubtless might afford good living to birds of 
this family, 
-p21. Harelda glacialis. Long-tailed Duck. 
We observed a flock of this species swimming in the pools 
of water between the floes on the 1st September, 1875, near 
Floeberg Beach (lat. 82° 27' N.). On the 16th September 
two were shot not far from the ship. During the summer of 
1876 a few of these birds visited the northern shores of Grin¬ 
nell Land ; we found them in pairs on lakes and ponds, where 
they were evidently breeding. From the rapidity with which 
they dive they are very difficult to shoot, and when secured do 
not repay the outlay in powder and lead. 
22. Somateria mollissima. Eider. 
This species breeds in great numbers in the neighbourhood 
of Port Foulke, but decreased in numbers as we advanced 
northwards. It became rare after passing Cape Fraser, the 
meeting-place of the polar and Baffin-bay tides, but was re¬ 
placed to some extent by the next species. I did not obtain 
an Eider north of Cape Union. Dr. Coppinger procured both 
Eider and King-Duck at Thank-God Harbour (lat. 81° 38' N.) 
in the month of July, 1876.
