extent of the island was scarcely half an acre.” '
Professor Nilsson says this species is found oirmost of the
shores and islands of Sweden and Norway; it is also found'
at Iceland. A single specimen was seen by^our Arctic
voyagers in' Baffin’s Bay, and the species was included by
Fabricius in his Birds of Greenland. According to Mr. Audubon
the Great Black-backed Gull inhabits North America.
This species is observed on the coasts of-Germany, Holland,
and France ; it is included b y M . Savi,‘ib Ms Birds of
