GUILLEMOT. — Urta troile. 
There are several other species belonging to this sub-family, among which may be 
mentioned the Black Guillemot ( Uria grylle ), known by its smaller size and its black 
plumage with a large white patch on the wing. The Little Auk, or Rotche (Alle nigricans ), 
so well known in northern seas, also belongs to the same group. 
The Black Guillemot ( Uria gryll'e) is a common inhabitant along our Atlantic coast in 
winter, where it is called Sea Pigeon. 
The Murre ( Lomma troile) is a common visitor on the Atlantic coast in winter, and also 
on the North Pacific. It reaches as far south as New Jersey and California. Thirteen other 
species of Guillemot are known to the American Avi fauna — all inhabiting the North Pacific 
coast. 
THE PETRELS. 
The curious family of the Petrels now comes before us. A well-known example is the 
Stormy Petrel (Pr ocellar ia pelagica), known to sailors as the Mother Carey’s Chicken - , 
and hated by them after a most illogical manner because it foretells an approaching storm, and

which it frequents. It swims and dives wonderfully well, and feeds largely on cuttle-fish. Dr. 
Bennett has given an admirable description of this bird and its habits, as it appeared on Mac- 
quarrie’s Island, in the South Pacific Ocean. 
The common Guillemot is an example of the next sub-family. 
This bird is found plentifully on our coasts throughout the year, and may be seen swim- 
ming and diving with a skill little inferior to that of the divers. It can, however, use its legs 
and wings tolerably well, and is said to convey its young from the rocks on which it is hatched, 
by taking it on the back and flying down to the water.
