LAMELLIROSTKAL SWIMMERS — ANSERES. 



Sylvie's valley, iu the Blue Mountains, their trumpetings were heard as late as May 

 29. They feed on the small bulbous roots of a water-plant growing near the shores of 

 the lake. He thinks that none breed there, and that only disabled ones remain on the 

 Oregon lakes in the summer. 



Specimens of this Swan were procured by Mr. Kennicott on the Porcupine Kiver, 

 and others by Mr. J. Reid on Big Island. They were obtained on the Anderson and 

 Swan rivers, as also on the Barren Grounds and the islands in Franklin Bay, in the 

 Arctic Ocean, by Mr. JNIacFarlane. 



The eggs of this species — those from Anderson River as well as those from the 

 Yukon — are all alike, and vary but little in size or color. They are of a uniform 

 unspotted buffy white color, becoming yellowish wlien exposed to the weather. Three 

 of these eggs furnish the following measurements : 4.05 inches by 2.55, 4.25 by 2.80, 

 and 4.25 by 2. 05.
