26 GEOLOGICAL SURVEY OF CANADA, 
Not observed in Hudson Strait ; abundant and breeding on the 
eastern and southern shores of Labrador. (Packard.) Not rare 
in West Greenland, but unknown in East Greenland. (Arct. Wan.) 
Breeds, but not in large numbers, on the Great Bird Rock, Bryon 
Island and Entry Island, Magdalen Islands, Gulf of St. Lawrence. 
(Bishop.) Common along the St. Lawrence at Kamouraska, Que. 
(Dionne.) Common from the middle Labrador coast to Frobisher 
Straits ; they are not found in Cumberland Gulf, but are by no 
means rare onthe west coast of Greenland. (Kwmelin.) 
The first notice we have of the occurrence of this species in 
Ontario is in the published proceedings of the Canadian Institute. 
The specimen there recorded was taken on December Ioth, 1889 ; 
a second specimen was taken near the west end of Lake Ontario 
in November, 1871, and Mr. J. H. Fleming mentions another as 
having been taken near Hamilton. 
BREEDING Nores.—This species breeds abundantly at Gannet 
Islands, coast of Labrador. Mr. Dick collected a number of eggs 
for me on July 2nd, 1895. Like the common Murre, this bird 
lays its egg on a ledge of the sea-cliff. This species, like the 
Black or Pigeon Guillemot, sometimes lays two eggs, but one is 
the usual number. (Razne.) 
MUSEUM SPECIMENS. 
One specimen obtained on the Atlantic coast, purchased with 
the Holman collection. 
Four eggs are in the collection. Two of these were obtained 
by Mr. A. P. Low at Davis Inlet, coast of Labrador ; two others 
were received from Mr. Raine, who obtained them from Labrador.
