490 PH@NICOPTERUS ROSEUS.—CYGNUS OLOR. 
while incubating sat astride of the nest, which has been shewn not to be the 
case (naturally enough) when it is in shallow water that would not admit 
of her doing so, but it remains to be proved that the old and wide-spread 
belief is incorrect, when the water is deep and the nest high. ] 
[§ 5367. Two.—Bubian, Persian Gulf, 25 May, 1878. From 
Colonel Butler, through Mr. Howard Saunders, 1879. 
Mr. Saunders informed me that he believed Colonel Butler did not take 
these himself, but obtained them from one of his friends. Seventy-one 
specimens taken at the same place and on the same day are entered in the 
‘Catalogue of the Collection of Birds’ Eggs in the British Museum’ (ii. p. 137) 
as the gift of Mr. Hume, who has some remarks upon them (Stray Feathers, 
x. p. 513); but the Colonel does not seem to have published any notice 
concerning them. | 
CYGNUS OLOR (Linnzus). 
MUTE SWAN. 
§ 5368. Oxe.—Eton, not later than 1843. 
I much fear that this is the egg of one of Her Majesty’s Swans. 
It was procured at Eton by a man known as ‘ Musky,” who is 
since dead. 
§ 5369. One.—St. James’s Park, 1852. 
Obtained by me from Smith, the keeper of the Ornithological 
Society’s Waterfowl in St. James’s Park. 
[§ 5370. One.—Hillingdon, Middlesex, 1846. From Mr. 
Charles Cox.

[§ 5371. Oxe—Culford, Suffolk. From Mr. E. R. Benyon, 
1846.

least was commonly kept. ]
