454 Mr. A. G. More on the Distribution of Birds 



a few scattered localities from Sussex to Orkney. As Macgilli- 

 vray remarks, most of its breeding- stations are on the east side 

 of Great Britain ; and this is also the case with the other Terns, on 

 account of the greater prevalence on the east coast of the low 

 sandy shores and islets which these birds prefer for their nests. 



Hydrochelidon fissipes {G. R. Gray). Black Tern. 

 Provinces III. IV. [VIII.]. 

 Subprovinces y, (10), ii, (12), (19). 

 Lat. 51°-53°. " Germanic " type. Not in Ireland ? 



This is one of the birds whose numbers have greatly dimi- 

 nished of late years ; for although Mr. Hewitson describes it as 

 '^ abundant in some parts of the counties of Cambridge and 

 Lincoln," I believe that it has nearly, if not entirely, ceased to 

 breed in this country. 



A pair or two are considered still to nest occasionally in Kent 

 and Norfolk ; but I am assured by various correspondents that 

 the Black Tern has become altogether extinct in the counties of 

 Suffolk, Cambridge, Huntingdon, and Lincoln. 



Larus ridibundus (Linn.). Black -headed Gull. 

 Provinces III. IV. V. ? VIII.-XVIII. 

 Subprovinces 7, 8, (10), 11, 15?, 19, 21, 22, 24-38. 

 Lat. 50°-61°. " Scottish " (or " British ") type. 



A few breeding- stations occur in the south of England, in the 

 counties of Kent, Essex, Norfolk, and Lincolnshire; but the 

 localities for the bird ai'e much more numerous in the north. 



Plott mentions a locality in Staffordshire, but I do not know 

 whether the birds still frequent this county during the breeding- 

 season. 



RissA TRiDACTYLA {MacyilL). Kittiwake. 

 Provinces LIL?X.-XVIIL 

 Subprovinces 1-3, 4?, 22, 24, 25, 27-38. 

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



On the south coast, the Kittiwake has been stated to breed 

 in Dorsetshire; but I have been unable to obtain any confirma- 

 tion of this assertion. It is certainly not found in the Isle of 

 Wight during the nesting-season.
