486 BRITISH BIRDS. 
ACREDULA CAUDATA ann ACREDULA ROSEA. 
CONTINENTAL LONG-TAILED TIT and BRITISH 
LONG-TAILED TIT. 
(Piare 9.) 
These two forms are united together by a series of intermediate examples, 
which are found in those districts where their respective ranges meet, 
leading to the supposition that they are only subspecifically distinct and 
interbreed wherever they have the opportunity. The synonymy of the two 
forms is as follows :—

The British Long-tailed Tit is by no means confined to the British 
Islands. In England and Wales it is generally distributed and probably 
breeds in every county, although it becomes somewhat local in certain 
districts. In the Channel Islands, Mr. Cecil Smith remarks that he 
has never met with it; but Professor Ansted, in his list, states that it 
occurs in Guernsey and Sark. In Scotland, although generally distributed, 
it is rarer, doubtiess because the districts suited to its habits are fewer ; but 
it is more numerous in winter. It is also found on some of the Inner
