Was discovered by Captain Sabine on the three islands of Baffin, during Captain 

 Ross's first voyage to these regions in 1818, and described by Mr. Sabine with minute 

 accuracy in the Transactions of the Linnaean Society, loc. cit. 



Since that period it has been found in many parts of the Arctic Regions ; at Spitz- 

 bergen, Igloolik, and Behring's Straits; and by our party as we travelled along the 

 coast, a little to the southward of Cape Garry. I have no doubt that the low land 

 where it was met with, is one of its breeding-places. 



I have lately heard that it has also been found on the west coast of Ireland, so that 

 It has a much more extensive range than was at first supposed ; and it is the more 

 extraordinary that it remained so long unknown to naturalists. 



Only one specimen was obtained by us at Felix Harbour; it was shot by Dr. 

 M'Diarmid, and was the only one seen during our three years' residence in that 

 quarter. The Esquimaux informed me that it breeds in great numbers on the low 

 land west of Neityelle. 



Dr. Leach founds its generic distinction on the forcature of the tail : for a similar 

 reason the L. Rossii should also form the type of a new genus, no other known Gull 

 having a cuneiform tail.
