GREAT CRESTED GREBE 
Dublin, and once or twice on Lough Neagh. It is reported 
to occur off Galloway on migration in early spring and late 
winter ; on the English side few have been obtained. It 
breeds in the Outer Hebrides, possibly in Orkney and Shet- 
land, where, however, it is always rare. 
COLYMBUS SEPTENTRIONALIS, Linn. 
BED-THROATED DIVER. 
This species is probably of regular winter occurrence 
around the island. About the end of September 1890 a 
beautiful specimen, with grey head and red throat, and very 
little spotted, was killed at Douglas near the Victoria Pier, 
and came into possession of Mr. Kermode ; it is now in the 
Kamsey Museum. During the following winter several 
frequented the bay, fishing frequently between the Pier and 
Conister, and were readily observed. They swam very 
much submerged, often with the head and neck almost 
buried, and seemed merely to sink in diving, not throwing 
themselves out of the water in the fashion of Shags. 
This species is of regular occurrence in the Irish Sea, as 
on all British coasts and estuaries, and on its western side 
appears to be considered the commonest Diver ; it has even 
bred in Donegal. On the other coasts it is not considered 
numerous. It breeds in Shetland, in Hoy, and in some of 
the Outer Hebrides.
