DISTRIBUTION. 
Breeding range.—Coasts and islands of the North Atlantic. From 
the Gulf of St. Lawrence (Bird Rock and islands along north shore) 
and Newfoundland, northward along the Labrador coast to southern 
Greenland. Also from Portugal (Berlenger Islands) and western 
France, northward through the British Isles to the Faroe Islands, 
Iceland, and Norway (Varanger Fiord). 
Winter range—From Labrador (Hamilton Inlet), Nova Scotia, 
and New Brunswick to coast of Maine, rarely to Massachusetts (one 
specimen in Boston Society of National History. All other recent 
records refer to Briinnich’s murre with little doubt). The Rhode 
Island record is considered very doubtful and all from south of New 
England can not be verified, but probably refer to lomvia. In Eu- 
rope from the British Isles south to the west coast of Morocco; oc- 
casional in the Mediterranean Sea (Malta) and recorded from the 
Canary Islands. 
Casual records—Recorded from York Factory, Hudson Bay, by 
Swainson and Richardson, and taken by Bell in Hudson Bay in 1885. 
Egg dates —Gulf of St. Lawrence: 35 records, May 20 to July 25; 
18 records, June 18 to July 1. Great Britain: 20 records, May 10 to 
June 19; 10 records, June 5 to 18. Newfoundland: 3 records, June 
14 and 20 and July 3. 
URIA TROILLE CALIFORNICA (H. Bryant). 
CALIFORNIA MURRE, 
HABITS. 
The Pacific coast subspecies of the common murre differs but 
slightly in appearance or in habits from its relative of the Atlantic 
Ocean; it is somewhat larger and its bill is a little different in shape 
and relative dimensions; its life history is so similar that I shall not 
attempt to repeat what I have said about the foregoing bird, but 
shall endeavor to give what additional information we have relating 
to the California murre and describe a few of its most striking breed- 
ing colonies. Whereas the Atlantic murre is now confined, in the 
breeding season, to a few restricted localities on the American side 
of the ocean, the California murre is very widely distributed all 
along the Pacific coast, breeding in nearly all suitable localities, from 
the Santa Barbara Islands, off southern California, to the Pribilof 
and other islands in Bering Sea. Moreover, the common murre is 
comparatively rare as an American bird, whereas the California 
murre is excessively abundant throughout most of its range. 
The name, California murre, at once suggests the Farallone Islands, 
one of the largest and certainly the most famous of the breeding
