Birds peculiar to the British Islands.—At the Conversazione 
of the Royal Society held at Burlington House on June 19th, 
1907, Dr. Ernst Hartert exhibited a series of birds 
represented in the British Isles by peculiar forms, and 
examples of their Continental allies, for comparison. ‘The 
following remarks were attached to the “ exhibit ”:— 
“As late as 1892 Wallace accepted only three birds as 
peculiar to the British Isles (‘Island Life,’ p. 340), and 
even more recent works have not mentioned more than three 
or four. Careful investigations, however, have shown that 
about twenty British birds present constant and often easily 
recognised differences from their Continental allies. Eighteen 
of these are exhibited, with their allies, in order to shew 
their differences.” 
The list of birds exhibited, which has been kindly supplied 
to us by Dr. Hartert, is as follows :—
