and Mr. Crotch tells me that the bird breeds also in Somerset. From 

 this point I am unable to trace any locality until we reach the Isle of 

 Man, where Mr. Crellin says that it breeds annually. 



On the east coast of England, the Kittiwake breeds at Flamborough 

 Head and at the Farn Islands, off the coast of Northumberland. It is 

 .also abundant in many different parts of Scotland, especially in the 

 western and northern isles.

Breeds in Cornwall (Mr. E. H. Rodd}, in North Devon (Rev. M. A . 

 Mathews}, and in Somerset (Mr. W. D. Crotch} ; in Pembrokeshire 

 (Mr. J. Tracy} ; and in Cumberland (Mr. T. Gough}. On the east 

 coast of England, the Rev. J. C. Atkinson assures me that the Common 

 Gull breeds in the Essex Marshes, where it is rare. It is believed to 

 nest on the cliffs of Yorkshire ; but it appears to be a scarce bird in 

 most of the English localities, and seems to be wanting also in several 

 of the Scottish districts. 



LARUS FUSCUS (Linn}. Lesser Black-backed Gull. 



Provinces I. II. VI. VII. XI.-XIV. XVI. -XVIII. 

 Subprovinces 1-3, 5) 6, 17, 18, 24-28, 32-38.

Like many other of our sea-fowl, the Lesser Black -backed Gull 

 becomes much more numerous northwards, though it is too generally 

 distributed to be placed under the Scottish type. 



LARUS ARGENTATUS (Briinn.}. Herring-Gull. 



Provinces I.-III. VI. VII. X.-XVIII. 



Subprovinces 1-7, 17, 18, 22, 24-38.

This appears to be the most widely distributed of all our Gulls, 

 being found on all the rocky parts of the coast during the breeding- 

 season. 



LARUS MARINUS (Linn.}. Great Black-backed Gull. 



Provinces I. VI. VII. ? XII.-XIV. XVI. XVIII. 



Subprovinces 1, 2, 17, 18?, 25-28, 32-38. 

 Lat. 50-61. " Scottish" type, or northern. 



It is only in the north of Scotland that the Great Black-backed Gull 

 is at all numerous. The few localities in which it has been found 

 breeding in England are scattered along the west coast, from Cornwall
