LARID^E. 149 



near Eton ; and in November, 1865, an Arctic Tern 

 was obtained at Boveney Locks. I have seen seve- 

 ral preserved specimens v^diich had been killed at 

 various times in the immediate neighbourhood of 

 Windsor. Towards the end of May, 1866, Mr. Gould 

 killed one near Maidenhead,* which he afterwards 

 preserved. 



Lesser Tern {Sterna mimitd). Local name, Little 

 Sea Sivallow. This Tern is a summer visitor to 

 England, and has on several occasions been shot 

 on the Thames in spring and autumn. It does not 

 appear to be at all an uncommon bird, and the fol- 

 lowing is a summary of the more recent instances of 

 its occurrence in these counties, so far as I have been 

 able to ascertain. 



One was killed while flying about the canal at Slap- 

 ton, in May, 1850, as I was told, by the Rev. Bryant 

 Burgess, of Latimer, near Chesham. In the month 

 of July, 1867, I examined a bird of this species which 

 had been shot a few days previously on the river near 

 Windsor. Others occurred about ten years since near 

 t*he same place, and I have seen several more which 

 have been procured in the vicinity of Eton at different 

 times. Mr. R. B. Sharpe informed me that an imma- 

 ture specimen of the Lesser Tern was presented to 

 him, which had been shot at Cookham Grove a few 

 years ago. 



Black Tern {Sterna nigra). Local name, Black 



* Vide Common and Black Terns.
