THE IVORY GULL. 

 Pagophila ebi'rnea (Phipps). 



The first British specimen of this truly Arctic (kill was obtained 

 by the late Dr. Lawrence Edmonston during the winter of 1822, in 

 the Shetland Islands, where this species has subsequently been 

 met with on several occasions. Four examples have been recorded 

 from the Orkneys, one of them as late in spring as May ; while 

 southward, Sutherland, Caithness, Banffshire and Aberdeenshire 

 have been visited, and six or seven birds have been killed in 

 south-western waters, chiefly off the Firth of Clyde. In England 

 this Gull is, naturally, more frequent in the north than in the 

 south ; but its migrations have extended to the Channel and Cornwall ; 

 while in Ireland two birds have been taken and others have been 

 observed. Altogether we may consider that about thirty specimens 

 have been procured in the British Islands, and, of these, rather 

 more than half appear to have been adults. 



The Ivory Gull has been noticed on the coasts of Northern
