WEDGE-TAILED GULL. Ehodosthetia rosea (Macgillivray). 



At a meeting of the British Ornithologists' Club, held 

 May 16th, 1906, Mr. H. E. Dresser exhibited eggs 1 of this 

 species obtained by Mr. S. A. Buturlin on the delta of the 

 Kolyma Kiver in North-east Siberia. These 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 glaucus (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. K. Warren (R. Warren, ' Irish 

 Naturalist,' 1905, p. 71). 



ICELAND GULL. Larus leucopterus (Faber). 



An Iceland Gull, in the white phase of plumage 2 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). 



IYORY 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 (T. E. Buckley, Ann. Scot. Nat. Hist., 1901, 

 p. 116). 



1 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. 



3 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 110 certain knowledge, though it 

 probably existed. The capture of Mr. Warren's specimen is therefore of 

 considerable interest.
