ORNITHOLOGY OF SECTION D, 1850. 
I will not attempt to speculate on the reason of this remarkable 
change of locality, in a bird supposed to be so constant in its at- 
tachment to certain breeding places. It is not found in Shetland 
or Orkney. St. Kilda is perhaps its only British and also its most 
southern station. It is, however, said to breed in the island of 
Barra, perhaps not South Barra, but Bara and Rona, two rocks 
far to the north of Cape Wrath and the Lewes, whose position was 
ascertained with accuracy in one of Parry’s Arctic Voyages. The 
Westmanna Islands, where the Fulmar is described as so abundant, 
are to the south of Iceland, and not in Faroe, as Mr. Yarrell in- 
advertently states. 
Thalassidroma pelagica lives in any hollow or burrow, even 
under the floor of a barn. It is in many localities, breeding late 
inJuly. I looked in vain for the nearly allied species, 7. leachii, 
which is found in St. Kilda. 
Of the birds in my third list, I have to say, that I made the 
most diligent search and inquiry for them. ' 
Colymbus glacialis is believed, as in the north of Britain, to 
hatch its egg under its wing, so it is not likely that it ever bred 
in Faroe, 
Mergulus melanoleucos is stated to breed in the northernmost 
of the Faroe Isles, certainly through some mistake. I could neither 
find it any where, nor hear of any one who had seen it in summer. 
ven in Iceland I believe it is only known to breed in one island 
to the north, which lies on the arctic circle. It is a truly arctic 
rd, far more so than Uria grylle. 
About Alea impennis 1 made inquiries whenever I had oppor- 
tunity, but I could learn very little. An old man, Paul Joénsen, 
had Seen one fifty years ago, sitting among the Hedlafuglur, that 
'S Young Guillemots and other birds upon the low rocks, and old 
"i told him it was very rare. This was about the time when 
pe Wrote. Old people have been heard to say, that formerly, 
ee Many of them were seen, it was considered a sign of a good 
tae which we may perhaps explain, by supposing that the 
aes es of weather which prevented A. impennis going to the 
ee also kept more of his congeners from their far northern 
mg places, “A Gorrfuglur was formerly valued at four Lom-
