ALCA BRUENNICHI. 387 
§ 4855. Seventeen—Cape Dudley Digges. From Mr. Han- 
cock, 1851. 
Two of these are marked “ East side Davies Straits, 1839, 
[Lat.] 724. Capt. Warham.”’ Mr. Hancock wrote :—* The eggs of 
Uria bruennichi are from the former lot [§ 4854], all taken at 
[Cape] Dudley Digges, nearly at the top of Baffin’s Bay, where the 
Common Guillemot is not. The furthest north I ever knew the 
Common Guillemot to be is Iceland, where both species breed in 
the same rocks, Hence the specimens from the latter locality are 
not to be depended upon.” And again, “I think I have good 
grounds for stating that the Common Guillemot is not in Baffin’s 
Bay. Ihave been in the habit of receiving both skins and eggs 
[brought] from that country by whalers from this port [Newcastle] 
and others for upwards of twenty years, and during that time I have 
had numbers of the former [Briinnich’s] bird brought me, but 
never in one instance the Common Guillemot.” 
[Cape Dudley Digges is, however, far beyond Lat. 72° 30'N. According 
to Herr Winge (Grénlands Fugle, p. 221), Godthaab is the most northerly 
locality in Greenland whence our Common Guillemot is known. ] 
[§ 4856. Five-—Grimsey, Iceland. From Mr. Proctor, 1851. 
These cannot be accepted as being absvulutely free from doubt, though it is 
true that Icelanders who know both species of Guillemot have a distinct 
name for each and recognize the difference between the Stuttnefia and the 
Langvia or Langnefia. Moreover, according to Faber’s observation (Isis, 
1824, pp. 967-980), the former is much more numerous in Grimsey than the 
latter, and he states that they occupy different breeding-stations on the cliffs 
of the island—statements confirmed by Herr Hantzsch (Vogelwelt Islands, 
pp. 68, 112-117), who was there in 1903. This is all in favour of the 
specimens sent to Mr. Proctor being correctly named ; but there is yet the fact 
that the more southern species does breed there, and that unless due care 
were taken these eges might belong to it, a doubt to which specimens from 
Greenland and other more northern countries are not so liable. | 
[§ 4857. Zhree—North Greenland? From Mr. Hancock, 
through Mr. Wilmot, 1860. 
Mr. Wilmot’s Catalogue shews that all these were from Mr. Hancock— 
one through Mr. Hewitson, the other two directly. One of these last being 
marked “ East side Davies Strait, [lat.] 723, 1839,” is evidently from the same 
lot as those before entered here (§ 4855), while the other is inscribed 
“ Opernawick ” (Upernivik). }
