LAMELLIROSTRAL SWIMMERS — ANSERES. 
Sylvie’s valley, in 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 Biver, 
and others by Mr. J. Be id 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. MacFarlane. 
The eggs of this species — those from Anderson Biver 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 when 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 2.65.
