)int Barrow. {Murdoch^ They breed in great numbers throughout 

 I northern Alaska, both on the coast and in the interior, and on 

 e islands in Behring Sea and on the Aleutian Islands. {Nelson.) 

 mnin has seen it off the Pacific coast of British Columbia, and 

 ports it from Dease Lake in Cassiar and south to Okanagan. 



Breeding Notes. —On July 15th, 1895, Mr. Dicks collected some 

 utches of this Tern for me on Green Island, Sandwich Bay, 

 abrador. Nests in a hollow in the rocks, containing two or three 

 jgs each. This bird also breeds on the islands of Mackenzie 

 ay, Arctic Ocean, where eggs were collected for me on June 20th, 

 !q4. Nests, holes in the sand. {Raitie.) 



The ArcticTern is one of the earliest birds to arrive atSt. Michael, 

 laska. They become very abundant by the middle of May. 

 hey breed on the low grounds, preferably on a low, damp 

 land, such as those at the northern end of the " canal." 

 n this place hundreds of nests were discovered in 1876. The 

 ;st is merely a bare spot on the ground ; sometimes on y a few 

 ades of grass surround the margin of the nest, but these seem 

 I be more the result of cleaning off a bare spot than an attempt 

 I construct a nest. The eggs vary from one to two, never more. 

 '^umer.) 



On June 12th I found a nest upon a small wet islet near St. 

 !ichael. The island was covered with short grass. The nest 

 as lined with a few dry grass-stems and contained two eggs, and 

 le female bore another ready to deposit. Another nest similarly 

 tuated was lined with material procured within a few feet, and 

 le ground was turned up in small spots all about where the 

 rds had uprooted the grass, many small bunches being half 

 jrooted and left, the task proving too heavy. {Nelson) 



MUSEUM SPECIMENS. 



We have two specimens taken on Sable Island, N.S., August 

 )th, 1899. 



Our egg collection contains one set of eggs from the coast of 

 abrador procured from Mr. Raine ; one from Cape Prince of 

 ^ales and another egg from Repulse Bay, Hudson Strait, taken 

 f Mr. Guy in 1896. In July 1894, Dr. Klotz, Astronomer of the 

 epartment of the Interior, took a nest containing two eggs on 

 le border of the Baird Glacier, Thomas Bay, Alaska. There 

 as no pretense of a nest, only a hollow in the ground.
