EUROPEAN BIRDS OBSERVED IN NORTH AMERICA. 367 
for Naturvidensk.’ 1838, two specimens of this species were killed 
near Kongsberg, in Norway, in April, 1837; and the editors of the 
‘Analyst,’ Messrs. Hall and Neville Wood state (vi. p. 160) that 
one was killed on the Trent, near Gainsborough, in November, 
1836. 
Of those species which I have retained, some will, I believe, 
eventually be found breeding regularly in North America, and 
will be included in its fauna. 
The total number of species which I have included in this 
paper is fifty-six. Nine of these I have regarded as artificially 
introduced, and although I consider that as European birds in 
North America they are entitled to a place here, yet I have 
distinguished them by a different type from those which have 
probably wandered to America of their own accord. 
Of the remaining forty-seven species ten have appeared on 
the Pacific coast only, leaving thirty-seven as the number that 
may be regarded as having probably come from the European 
side of the Atlantic, whereas Mr. Dalgleish has been able to report 
sixty-seven species of American visitors to Europe in a note to 
his paper on that subject (Buli. Nutt. Orn. Club, January, 1881, 
vol. vi. p. 64). 
If we divide the forty-seven species which have wandered to 
North America into the convenient arrangement of Land Birds, 
Waders, and Swimmers, we find them distributed in the following 
manner :— 
Total number Eastern Greenland Pacific 
of species. | United States. North only. only. coast only. 
Land Birds 13 1 12. 6 5 
Waders . 17 5 10 8 1 
Swimmers . 17 6 9 6 3

Including one Wader in Nova Scotia and one Swimmer in 
Barbadoes. 
It will be seen from the foregoing table that of the thirteen 
species of land birds that have been found on the continent 
twelve have occurred in the northern part only (i. ¢., Greenland, 
Labrador, Alaska, &c.), and the single species which is reported 
from the United States (Buteo vulgaris from Michigan) is rather 
a doubtful record.
