1384 Birds. 



The kittiwake represented in the engraving (a young bird killed 

 shortly after the breeding season) affords a curious example of the 

 variations which frequently occur in the form and relative length of 

 the tail and wing-feathers of this and many other gulls. The tail in 

 the adult bird is square, or nearly so, at the end, whilst that of 

 the bird figured is considerably forked — a peculiarity which in 

 almost any other genus might be considered as a mark of specific 

 distinction. 



Ivory Gull, Larus ebumeus. Mr. Miller has a fine specimen, 

 killed some years since at Yarmouth. 



Common Gull, Larus canus. Common on the coast, except dur- 

 ing the nesting season, and most numerous in autumn. 



Iceland Gull, Larus leucopterus. Very rare in adult plumage ; 

 but the immature birds are not unfrequently met with late in the 

 autumn. 



Lesser Black-backed Gull, Larus fuscus. Occurs on the coast 

 throughout the year, except during the nesting season ; but not 

 in large numbers. 



Herring Gull, Larus argentatus. Common on the coast at 

 the same seasons as the last species. 



Great Black-backed Gull, Larus marinus. Common on the coast, 

 except in the breeding season. Both this and the two preceding 

 species are somewhat more numerous in autumn than at any other 

 time of the year. 



Glaucous Gull, Larus glaucus. Has been occasionally killed, 

 generally in immature plumage. 



Common Skua, Lestris catarractes. The common skua is some- 

 times met with in Norfolk; most commonly in autumn. 



Pomarine Skua, Lestris pomarinus. Of occasional occurrence ; 

 especially immature birds in autumn. 



Richardson's Skua, Lestris Richardsonii. The immature birds, in 

 various stages of plumage, are occasionally found in autumn ; but the 

 adult birds are rare. 



BufFon's Skua, Lestris parasiticus. The young birds not un- 

 frequently occur in autumn, in a manner similar to the preceding 

 species. 



Fulmar Petrel, Procellaria glacialis. Sometimes taken off the 

 coast in autumn. 



Manx Shearwater, Puffinus Anglorum. Rare. Sir Thomas Browne 

 refers to " a sea-fowl called a sherewater, somewhat billed like a cor-
