support Mr. Swinhoe's conclusions, which apply to the Philip])ine bird also, as well as to all those 

 I have examined from continental India. Although a small difference in the length of tail is, 

 by itself, a character too insignificant whereon to base a species, still it must be recollected that 

 the lines of migration of the two forms are perfectly distinct, the short-tailed birds breeding 

 in Northern Asia and visiting Southern Asia and its islands, those with the long tails breeding 

 in Northern Europe and wintering in Southern Europe, Asia Minor, and Northern Africa*. 

 Where the two races osculate remains an interesting point for future investigation ; and it is not 

 impossible that the race which winters in Abyssinia will be found to breed in Siberia.
