it so iioticeahle as in the Gull tribe. Vast numbers, in dread of 
being swept away before our autumn gales, are seen fighting against 
them in the autumn, generally in October and November.* — G. 
212. Herring Gull [Larus argentatus). 
Common, especially in immature plumage, when it is difficult to 
distinguish it from the young Lesser Black-backed Gull, though 
the present species is not so dark in appearance. 
21.‘1. Lesser BL.vcK-n.vdCED Gull {Larus fuscus). 
Common, especially in immature i)lumage, and in the autumn, 
along the coast, but .seldom .seen far inland. This Gull and the 
preceding seem to be about eipially abundant. 
214. Great Black-b.vuked Gull {iMrus marinus). 
Common, especially in autumn, along the coast, but seldom 
seen inland, and never so abundant as the previous two species. 
215. Glaucous Gull {lAints glaucus). 
Not uncommon in winter, though rare in adult plumage. In 
January, 1881, a great many were brought into Yarmouth by 
the fishing-smacks ; at the .same time several were shot opposite 
Y’armouth Beach and on Breydon Broad. It is impossible to 
say how many were actually killed, but from the information I 
have collected it appeai-s that from forty-five to fifty were offered in 
the llesh for sale in the town. — G. 
21G. Iceland Gull {Larus /eucopterus). 
An accidental winter visitant, fiir rarer than the Glaucous Gull 
A young female, in the possession of Mr. G. Smith, of Yarmouth, 
was shot on Caistor Beach in November, 1874. It has been 
examined and its identity confirmed by Mr. Howard Saunders. 
217. Kittiwake Gull {Rissa tridactyla). 
A spring and autumn visitant, also occurring in smaller numbers 
at other seasons. The adult seems commoner than the young, 
w’hich is the reverse of what is the case with the other Gulls. 
• In severe winters, .md in e.irly spring before going northwards, this 
species comes far inland, and frequents ploughed lands like the Black-headed 
Gull.
