LARIDJE. 
Mr. G. Jackson informs me that a gull of a pure white colour 
appeared, in January 1849, in the harbour of Glengariff (Bantry 
Bay), and remained for three days. He and others made every 
attempt to obtain it, but without success ; he was certain of its 
being the ivory gull, from descriptions of that bird which he had 
read, but he had never seen one before. An adult bird was picked 
up dead, but quite fresh, on the beach of the island of Achil, 
a few years ago, by a man of the Preventive Service. 
The ivory gull is an inhabitant of the arctic regions of both 
hemispheres, and but rarely moves so far south as the British 
Isles. The individuals known to have been obtained in Great 
Britain down to 1845 — the date of publication of the 2nd edition 
of YarrelFs ‘ British Birds ’ — were but four in number ; obtained 
in Shetland, the Clyde, Durham, and Yorkshire ; — but as many 
have since been recorded as procured at different periods in one 
of the southern counties of England, — Sussex.^ 
THE COMMON GULL. 
Larus canus, Linn. 
Is found around the coast at all seasons, but in smaller 
numbers than some other species. Inland, it and the 
black-headed gull are the most frequent. 
In the north-east of Ireland, at least, we do not find this species 
breeding commonly on the marine cliffs like the herring-gull. 
About the noble basaltic precipices of Antrim and Londonderry 
I have never met with it ; but we are told that, in the island of 
Bathlin, in June 1834, it “occupied one of the large natural 
amphitheatres formed on the north-western side of the island, and 
which seemed to be occupied by no other species. Their nests 
were placed towards the summits of the cliffs, in situations equal 1;
