scooped in the centre of the turf, in which the eggs were found lying on a very few 

 withered reeds. In the record, of one hundred and five nests, made by Mr. MacFar- 

 lane, in no instance were there more than two eggs in a nest. 



Mr. Adams (" Ibis," 1878) mentions this species as always to be met with, after 

 the first week in June, in the shallow bays along the coast of Norton Sound, where 

 these birds kept up a continual screaming throughout the day. They were said to 

 breed there ; but he was not able to verify the truth of the statement. 



The localities in the northern regions in which this Diver has been procured 

 are as follows : Fort Rae, Great Slave Lake, Fort Yukon, and the Yukon River 

 generally, by Mr. Kennicott ; Fort Rae, by Mr. B. R. Ross and Mr. L. Clarke ; Fort 

 Yukon, by Mr. J. Sibbiston and Mr. S. Jones ; Anderson River, Fort Anderson, the 

 Barren Grounds, Arctic coast. Rendezvous Lake, etc., by Mr. MacFarlane ; on the 

 islands in Liverpool Bay, islands in Franklin Bay, on Stuart's Island, by Mr, Pease ; 

 at Sitka, by Mr. Bischoff ; among the Gens de Large Mountains, by Mr. McDougall. 



The eggs of this species have a ground-color varying from a deep umber to a pale 

 greenish gray. The markings, like those of the torquatus (= imvier) and the septen- 

 trionaUs (= lumme), are of a deep brownish black. Three eggs from the Yukon have 

 these measurements : 2.95 by 2.00 inches ; 3.00 by 2.00 ; 3.25 by 1.85.
