The Scottish Naturalist. 
we may fairly assume that more of the latter have been observed, 
but not put on record. 
Black Guillemot {Uria grylle). Only on the coast, and 
uncommon there. 
Little Auk {Mergulus alle). This bird has occurred more 
commonly in the district than any other member of the family. 
Instances are at Harryburn (Lauder), Hendersyde Park (Kelso), 
Duns, and on the Tweed below Kelso, besides a large number of 
cases in Northumberland. In the autumn of 1876, and again in 
that of 1878, the bird was very plentiful on the coast. 
Pufi&n (Frafercula arctica). On August 4th, 1873, a specimen 
was caught in the Kale at Grahamslaw. 
Great Northern Diver ( Colymbus glacialis). Only found 
on the nearest part of the coast, where all of the three commoner 
species of diver are frequently met with. 
Black-Throated Diver {Coly^nbus arcticus). In the first 
week of April, 1876, and again on April 4th, 1877, a single 
specimen was obtained on St. Mary's Loch in Selkirkshire, while 
an example was killed at Bowhill on the lower part of the Yarrow 
shortly before 1876. The continual occurrence of this species 
in spring, at the same spot, induces the belief that a pair might 
possibly have remained to breed if unmolested. St. Mary's 
Loch is wild and suitable, but as it is far from their usual 
breeding haunts, this must be considered a very doubtful case. 
Red-Throated Diver {Colymbus septcnirionalis). Recorded 
from Weetwood, near Wooler, just beyond Cheviot, and from 
Bughtrig, on this side of it, the former in January, 1877. 
Great Crested Grebe {Fodkep 
cristatus). 
Red-Necked Grebe {Fodiceps 
griseigena). 
Sclavonian Grebe {Fodiceps 
auritus). 
Eared Grebe {Fodiceps nigri- 
collis). 
Little Grebe {Fodiceps fluviatilis). Breeds sparingly in the 
district, as at Mertoun and Roxburgh, at Nisbet and Lauder. It 
is often seen in other places, and will no doubt be found breed- 
All birds of the sea- 
coast, with the exception 
of an occasional straggler. 
Sclavonian Grebes are re- 
corded from Legerwood 
Loch, but the Eared 
Grebe is more common 
on the coast.
