in Great Britain during the Nesting-season. 455 



Mr. Rodd tells me that the Kittiwake breeds occasionally iu 

 Cornwall; the Rev. M. A. Mathews finds the nest in North 

 Devonshire ; 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 Flam- 

 borough Head and at the Farn Islands, off the coast of Northum- 

 berland. It is also abundant in many different parts of Scot- 

 land, especially in the western and northern isles. 



Larus canus {Linn.). Common Gull. 

 Provinces I. III. VI. X. ? XII. XIII. ? XIV. XVI.-XVIII. 



Subprovinces 1-3, 8, 17, 23 ?, 25, 26 ?, 27, 28, 32-38. 

 Lat. 50°-61°. " Scottish " type, or Northern. 



Breeds in Cornwall {Mr. E. H. Rodd), in North Devon {Rev. 

 M. A. Mathews), and in Somerset {Mr. W. D. Crotch) ; in Pem- 

 brokeshire {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 scai'ce 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. 

 Lat. 50°-61 . " British " type, or general. 



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 {Bininn.). Herring-Gull. 

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

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

 Lat. 50°-61°. " British " type, or general. 



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

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

 ing-season.
