ORNITHOLOGY OF THE BRITISH POLAR EXPEDITION. 207 
Korriwake, Rissa tridactyla.—Kittiwakes were numerous in 
Baffin’s Bay at the end of June. On the 16th July, 1875, I 
found this gull breeding in considerable numbers in Svarte Vogel 
Bay, lat. 69° 42’, in company with Glaucous Gulls, Iceland-Gulls, 
Cormorants, Looms, Rotches, Dovekeys, and Razorbills, the last- 
mentioned bird being the least numerous. Kittiwakes were not 
seen north of Foulke Fiord, lat. 78° 18’, where I obtained a speci- 
men and saw many more. I had no doubt they were breeding in 
this locality, which is apparently their northern limit. 
IcrLanp Gut, Larus leucopterus.—On July 16th, 1875, I took 
a young bird and an addled egg of this species from the same nest 
in Svarte Vogel Bay. The eggs were very like those of the Common 
Gull, the young bird being of a pale greyish brown colour. There 
were many Iceland Gulls in Svarte Vogel Bay. 
Guaucous Guu (“ Burgomaster”’), Larus glaucus.--On the 
16th July, 1875, there were many pairs, usually isolated, breeding 
along the shores of Svarte Vugel Bay. Constantly on the 
topmost spire of some pinnacled iceberg, this handsome gull 
takes up his position alone, the lower ledges being crowded with 
multitudes of meaner birds. In Foulke Fiord there were many 
pairs, where ] observed them foraging several miles inland: they 
are very voracious, and seem to be able to subsist independently 
of any open water, probably often depending upon Lemmings and 
other land animals for their food. Upon the 14th June, 1876, 
I saw a pair flying inland from Discovery Bay; this pair had, I 
believe, a breeding-place somewhere in the neighbourhood, as 
I saw them frequently at intervals till August lst; they seemed to 
subsist entirely inland, and made their appearance before there 
was any open salt water. I watched this pair several times sitting 
on, and hovering about, a fresh-water stream between two inland 
lakes in Musk-ox Bay, apparently fishing for Charr. Dr. Coppinger 
saw one Glaucous Gull in Polaris Bay in July, 1876. 
Ricuarpson’s Sxua, Stercorarius crepidatus.—In the month 
of June this bird was frequently seen in the North Atlantic, 
persecuting various Gulls. On the 10th July I watched a pair 
for some time near the small fresh-water lake a few miles inland, 
in Blase Dalen, Disco. I shot the male, and believe that they 
had been breeding in the neighbourhood. 
PoMATORHINE Sxua, Stercorarius pomatorhinus. — On the 
15th and 16th September, 1876, I saw several of these birds in
