WARBLERS. 107 
hypolais of most British writers is the rufa of the 
continent, the well-known Chiff Chaff. 
As an illustration of the way in which continental 
species sometimes find their way to England, and 
possibly to a place in the list of British birds, it may 
be remarked that in May 1868 Mr. J. G. Keulemans 
brought over three specimens of this bird from Hol- 
land, two of which he liberated at Harwich, the third 
having died on the passage.
