210 Dalgleish on North American Birds in Europe. 
the discovery has been made in an already thoroughly explored 
section. Whether this has any significance as indicating a special 
tendency of the genus to differentiation on account of changes in its 
environment, or is merely a coincidence, is of course problematical ; 
the question of an extension of range from some heretofore unex- 
plored habitat would also come in here for consideration.
