78 A NATURALIST IN THE MAGDALEN ISLANDS. 
107, MERGOLUS ALLE, (L.) Viewt. 
(SEA DOVE.) 
Mr. Whalen showed me a specimen which he killed on 
Bird Rock. He stated that they were occasionally seen in 
winter. 
108. URIA GRYLLE, (L£.) Brun: 
(BLACK GUILLEMOT.) 
A very abundant species. I arrived too late to find its 
eggs, but it breeds commonly at Wolf Island and Cap au 
Meule. A few breed on Byron Island, but none have been 
found on Bird Rock. 
109. LOMVIA TROILE, (L.) Brandt. 
(COMMON GUILLEMOT ) 
Very abundant on Bird Rock. Some few were found on 
Byron Island, but I did not observe any on the other islands. 
The young have their upper parts covered with a blackish 
down, mixed with silver gray; the under parts are white.
