breeds abundantly. Mr. Dunn says, this species is very 

 numerous both in Orkney and Shetland. It is found in 

 Scandinavia, at the Faroe Islands, in Iceland, and by our 

 Arctic voyagers in Greenland and Melville Island. Mr. 

 Audubon mentions it as plentiful in North America. 



This species is observed all the year on the coasts of 

 Holland and France ; both old and young are also ob- 

 served at Genoa in winter. Dr. Heineken includes it in 

 his catalogue of the Birds of Madeira ; and M. Savi in his 

 Birds of Italy. It is found at Corfu, at Crete, Sicily 

 and Malta ; and Mr. Drummond mentions that it is com- 

 mon, and breeds at Biserta. Mr. G. H. Strickland men- 

 tions, that Herring Gulls frequent the Golden Horn at 

 Constantinople ; it is found in Asia Minor, and on the 

 southern shores of the Black Sea. 



The adult bird in summer has the bill yellow, the angle 

 of the under mandible red ; edges of the eyelids orange, 

 the irides straw yellow ; head and neck all round pure 

 white ; the back, and all the wing-coverts uniform delicate 

 French Grey ; tertials tipped with white ; primaries mostly 

 black, but grey on the basal portion of the inner web; the 

 first primary with a triangular patch of white at the end, 

 the second and third with smaller portions of white ; upper 

 tail-coverts and tail-feathers pure white ; chin, throat,
