As long ago as 1822 the Aquatic Warbler must have been known to 
British ornithologists ; for Mr. J. H. Gurney, jun., has pointed out (‘Trans. 
Norfolk and Norwich Nat. Soc.’ 1871, p. 62) that the figure of the “Sedge- 
Warbler” in Hunt’s ‘ British Ornithology’ was evidently taken from an 
example of the present species. At least three other specimens have been 
recorded as British. Professor Newton discovered an example in the 
collection of Mr. Borrer, and exhibited it at a meeting of the Zoological 
Society (‘ Proc. Zool. Soc.’ 1866, p. 210), with the following note from its 
possessor :—‘‘ My specimen was shot on the 19th of October, 1858, in an 
old brick-pit a little to the west of Hove, near Brighton, and was stuffed 
by Mr. H. Pratt of that place. I saw it just after it was skinned. It was 
observed creeping about amongst the old grass and reeds.” In 1867 
Mr. Harting recorded the second example simultaneously in the ‘Zoologist’ 
(p. 946) and ‘ The Ibis’ (p. 468). It was obtained in the neighbourhood 
of Loughborough, Leicestershire, during the summer of 1864. 'The third 
example was recorded in the ‘ Zoologist’ for 1871 (p. 2521) by Mr. J. H. 
Gurney, jun., who detected it amongst a collection of British birds in the 
Dover Museum, Mr. Cordon, the curator, informed Mr. Gurney that it
