all islands and coasts of Labrador, Hudson bay, Newfoundland, 

 Nova Scotia and New Brunswick. It is also common in the Gulf 

 of St. Lawrence, breeding on the Magdalens, Anticosti and Prince 

 Edward island. Ascending the St. Lawrence, it nests on the 

 Thousand islands, where its nest was found by Rev. C. J. Young, 

 in June, 1895. Stragglers are found throughout Ontario, and it is 

 known to breed in several places. 



A summer resident in Manitoba and breeding. It is common 

 on all the large lakes of Saskatchewan and breeds in suitable 

 places. A few breed near Indian Head, but the greatest numbers 

 were found at Crane lake, about lOO miles east of Medicine Hat; 

 it was also seen in 1895 ^^ Cypress lake and southwestward to 

 Waterton lake near Chief mountain, and north to Lac Ste. Anne, 

 Alberta.

Breeding Notes. — I visited a colony near Souris, Prince Ed- 

 ward Island, July 7th. 1892, consisting of perhaps about 75 pairs. 

 Several nests found contained three eggs each and were the usual 

 depressions in the plains of drifted sand, protected possibly by a 

 few wisps of grass wound round the edge of the hollow. {Dwight^ 

 Breeding extensively on the shores of the Arctic sea as well as on 

 islets in many of the inland lakes of the forest region and " bar- 

 rens." {Macfarlane) Breeding in large numbers on a small island 

 in Crane lake, Saskatchewan, June 9th-20th, 1894. Nest, a shal- 

 low hole in the ground lined with dry grass. Of the hundreds of 

 nests that I saw each contained three eggs, except two, and they 

 had four. A number of the young were hatched by June 20th. 

 A few were found breeding by Deep lake, Indian Head, Sask., 

 June 3rd, 1892. Common from Moose Factory to Richmond 

 gulf, Hudson bay; breeding in June, 1896. {Spreadboroiigh.) 



On June i8th, 1894. on an island in Shoal lake, Manitoba, I 

 found thousands of this tern breeding; their nests were hollows 

 in the sand, lined with bits of drift-weed and contained three eggs 

 each. I found it breeding under like conditions on many of the 

 .dkes of Saskatchewan in June, 1891 and 1893. {Rai?ie.) 



This species was formely very plentiful in the River St. Law- 

 ence from Kingston eastward. Numbers bred on Salmon island.
