Solan Goose, _Sula bassana_.--At Cape Wrath and other stations upon our coasts, an extraordinary annual migration of Solan Geese is witnessed. Mr. M'Gill has reported to me specially on that of 1879, and kept as accurate a record as possible of the numbers which he estimated to pass westward. He writes as follows:--"The number of Solan Geese that migrate past Cape Wrath is beyond anyone's power to number, but I have come as near to it as possible. The first half of July the flocks were composed of old birds, and the rest of the time they were mixed old and young." Mr. M'Gill then gives the following list of Solan Geese seen passing west on fifteen days, between 14th July and 9th August, which I reproduce here:--
