76 RESIDENTS AND MIGRANTS. 



AECTIC TEEN. Sterna hirundo, Linnaeus. 



A summer visitant. This is the Sterna macroura of 

 Naumann, ' Isis,' 1819, p. 1847 ; Sterna arctica of 

 Temminck, Man. d'Orn. (1820) vol. ii. p. 742. 



EOSEATE TEEN. Sterna dougallii^ Montagu*. 



A rare summer visitant. The breeding-stations of 

 this and the last-named species will be found ad- 

 verted to by Mr. A. G. More in 'The Ibis' for 1865, 

 p. 452. 



SANDWICH TEEN. Sterna cantiaca, Gmelin. 



A summer visitant, but very partial in its choice of 

 breeding-ground. 



LESSEE TEEN. Sterna minuta, Linnaeus. 



A summer visitant, but somewhat restricted in its 

 distribution during the nesting-season. 



BLACK TEEN. Sterna fissipes, Linnaeus. 



A spring and autumn migrant but formerly a 

 regular summer visitant, breeding in several of the 

 eastern counties. 



LITTLE GULL. Larus minutus, Pallas. 



Irregular visitant in autumn ; the individuals ob- 

 tained are usually birds of the year or adults in winter 

 plumage. 



* The more appropriate name, Sterna paradisea, Briinnich, is un- 

 fortunately precluded from use, under the rules for zoological nomen- 

 clature, in consequence of having been bestowed prior to 1766, the 

 date of the 12th edition of Linnaeus's ' Systema Naturae.'
