in 1819 in the sale catalogue of Bullock's Museum, 

 wherein a specimen was included as " an un- 

 described Gull, much allied to the Arctic, but greatly 

 superior in size : killed at Brighton." Since that 

 date the species has been generally recognised, and 

 found to occur sporadically in autumn, chiefly on 

 the east coast, where in the autumn of 1879, and 

 again in October of the following year, an unusual 

 number of these birds were observed. During a 

 gale on Dec. 22, 1894, a bird of this species was 

 shot on the river Eden near Carlisle (Macpherson, 

 Zool, 1895, p. 22). 



On the south coast a few sometimes remain dur- 

 ing the winter, and occasionally are driven inland 

 by storms. Of late years the Pomatorhine Skua has 

 been noticed in some numbers every summer in 

 the Hebrides (Harvie-Brown and Buckley, " Fauna 

 of Sutherland," p. 235). It is believed to breed 

 usually on the tundras of Asiatic Siberia, where, in 

 lat. 74° N., Middendorf found the eggs, and Mr. 

 Popham in 1895 found nests near the mouth of the 

 Yenesei.
