348 LAEID^. 



Mr. G. Jackson informs me that a gull of a pure white colour 

 appeared^ in January 18-19, in the harbour of GlengarifF (Bantry 

 Bay)j 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 tliat 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 Yarrell's ' 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. 



Lams camis, 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 

 Rathlin, 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]
