Colymbus--A Diver, Glacialis—Of or belonging to ice, 
Tus Great Diver is in Europe found in Iceland, Spitz- 
bergen, the Faroe Islands, Russia, Norway, Sweden, Denmark, 
Lapland, Finland, Holland, Switzerland, Germany, and France, 
but in the latter only rarely in comparison with the former, 
and in Italy a single specimen is all that has occurred. 
In America in Labrador, Greenland, the Fur Countries, and 
thence on to the United States. 
In Cornwall one was taken in May 1828, near Polperro, 
and two remained near Looe the whole of that summer. 
They are not uncommon on that coast in winter. Two were 
seen off Hast Looe on the 25th. of October, 1852, and one, 
no doubt of the same pair, a female, was shot on the 8th. of 
November. In the following year, in the month of December, 
they were unusually abundant in that locality, ten or a 
dozen being not unfrequently seen at a time, and in one 
instance upwards of thirty. Several were seen in Plymouth 
Sound in December, 1850, and two of them were shot. One, 
a male, was obtained in Carrack Road, Falmouth, in March, 
1845, and another in January, 1846; one in Gwyllyn Vase 
Bay, in December, 1847; and on the 28th. of December, 
1848, two others were seen there. One has visited the bay 
every year for several years in May. Near Penzance in like 
manner they have occurred—one in October, 1844; two in 
October, 1849. They are met with in the immature plumage
