THE IVORY GULL. 
PaG6PHILA EBURNEA (Phipps). 
The first recorded British specimen of this truly Arctic Gull 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 re- 
corded from the Orkneys, one of them as late in spring as May ; 
while the Outer Hebrides, Sutherland, Caithness, Banffshire and 
Aberdeenshire, and even Roxburghshire 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, and, exceptionally to Wales ; while in 
Ireland two birds have been taken and others have been observed. 
Altogether it may be considered that about thirty-five specimens 
have been procured in the British Islands, and, of these, rather more 
than half appear to have been adults.
