ADDENDUM 581 
WEDGE-TAILED GULL. Lhodosthetia rosea (Macgillivray). 
At a meeting of the British Ornithologists’ Club, held 
May 16th, 1906, Mr. H. E. Dresser exhibited eggs! of this 
species obtained by Mr. 8. A. Buturlin on the delta of the 
Kolyma River in North-east Siberia. ‘hese were the first 
authentic eggs of this rare Gull which had ever been seen 
in the country (Bull. B.O.C., vol. xvi, p. 97, also ibid., p. 
41, and ‘Ibis,’ January, 1906). 
LITTLE GULL. Larus minutus (Pallas). 
A Little Gull was obtained near Lendalfoot, in the south 
of Ayrshire, on December 16th, 1902, by Mr. Charles Berry 
(John Paterson, Ann. Scot. Nat. Hist., 1903, p. 119). 
GLAUCOUS GULL. Larus glawcus (O. Fabricius). 
An immature example of this Gull, probably in its first 
year’s plumage, was obtained at Moyview, co. Sligo, Feb- 
ruary 14th, 1905, by Mr. R. Warren (R. Warren, ‘ Irish 
Naturalist,’ 1905, p. 71). 
ICELAND GULL. Larus leucopterus (Faber). 
An Iceland Gull, in the white phase of plumage” which 
immediately precedes maturity, was shot on the Moy estuary 
on April 26th, 1905, by Mr. R. Warren (R. Warren, ‘ Irish 
Naturalist,’ 1905, p. 135). 
IVORY GULL. Pagophila eburnea (Phipps). 
A fine adult Ivory Gull was obtained at Broadford, Skye, 
about February 6th, 1901; it was sent to Inverness by Mr. 
James Ross (TI. E. Buckley, Ann. Scot. Nat. Hist., 1901, 
p. 116), 
' The reader’s attention is drawn to a quotation inserted on p. 408 
of the text with regard to the eggs of this Gull, which, when the article 
was written, were still undiscovered. 
* The reader’s attention is directed to a foot-note on p. 445 of the 
text, where I have stated that I have not seen the pure white phase of 
plumage in this Gull. This plumage is evidently not well known, thus in 
Cat. Birds Brit. Mus., vol. xxv, p. 296, Mr. Saunders remarked that of 
the white phase of plumage he had no certain knowledge, though it 
probably existed. The capture of Mr. Warren’s specimen is therefore of 
considerable interest.
