Mr. Seebohm however enumerates seven established 
znstances of its occurrence. 
Mr. H. Saunders also mentions these occurrences; 
and concerning one of them has the following: 
As vegavds the occurrence of Bonaparte’s Gull in 
Scotland there 1s not the smallest doubt. 
About the end of April, 1850. Sir G. H. Letth- 
Buchanan shot a fine adult specimen ; a portract of which 
was sent to ihe author ( Yarrell) and clearly identified; 
but as some scepticism had been recently expressed, tn a 
standard work on Ornithology, Sir George sent the bird to 
the Editor, who exhibited it before the Meeting of the 
Zoological Society, on the 4th March, 1884. (The B.O.U. 
List was published 1883.) 
The egg in the Edinburgh Museum, a gift of the 
Smithsonian Institute, is rather larger than the egg of 
the Common Tern; oval; clear greenish ground colour; 
umber blotches; small, even, underlying purplish marks: 
in size nearer to Mr. Saunders’ dimensions than to those 
of Mr. Seebohm. 
tHE, LAUGHING GULL. 
(Larus ATRICILLA.) 
Rejected from the B.O.U. List. 
Rejected by H. Saunders. 
Rejected by Seebohm, 
who points out that the specimen stated in the B.O.U. 
List to be in the British Museum is ‘ Ridibundus.’ 
Mr. Seebohm says the egg which he depicts, is in- 
distinguishable from that of ‘ Ridibundus.’ 
My eggs, however, taken 3rd June, 1884, in Florida, 
are larger.
