* The form B. menetriesi, Bogd., is not separable. It appears to rest 

 upon birds with a fully rufous tail and the bands obsolete, except the sub- 

 terminal one, bvit there is no doubt these are only very old birds and there is 

 no means of distinguishing European from Asiatic examples in the various 

 other stages of tail marking, while the red stage seems common to both. 

 Both forms migrate to Africa.
