dimensions are 3.09 by 2.18inches. Dr. Coues says some 
eggs measure less than 3, by more than 2 inches; of these 
eggs my first mentioned is the smallest, and those found 
by Macfarlane the largest : I do not, however, know that 
the variation is more than that of many birds; of Bewick’s 
Swan, for instance, which varies, according to Mr. See- 
bohm, from 4.30 to 3.80 in length, by from 2.65 to 2.55 
inches in breadth. 
My third egg was taken by Mr. M. D. Smith from 
a nest formed of grass, and weeds, on the marshy shore of 
the Great Salt Lake, B.A., on June 13th, 1882, the nest 
contained six eggs; the incubation had not commenc- 
ed, it was of the sinaller dimensions and of the same un- 
mistakable character with the other described above. 
BEWICK’S SWAN. 
(CyGnus BEWICKI.) 
This bird seems to be restricted, by Mr. Seebohm, to the 
Eastern Hemisphere, and he says it does not breed in 
Iceland. Yet we learn from the U.S. ‘ Bulletin’ that the 
description of birds killed at ‘Ig/oolic, an Arctic America 
latitude 66° on Fune 19th, 1823, 1s of the true O. minor, 
or Bewtch’s Swan’; and that it is “ sazd to breed on 
the sea coast within the Arctic circle.’ Clearly if the birds 
were at Igloolik late in June, they must have been 
breeding in the Western Hemisphere ; and the species 
would thus surely include Iceland in its breeding range. 
Concerning the egg in my possession, Herr Schliiter 
writes, “ This egg I received from my late friend Mr, 
Foster, of Copenhagen ; it comes from Iceland.” The 
egg is white as that of the Pink-footed Goose.
