THE BULLFINCH 93 



(Pyrrhula pyrrhula pileata, MacGillivary, is the 

 title of our British bullfinch, which differs slightly 

 from the Continental bird P. p. europoea, Vieillot, 

 in that the female is greyer. P. p. pyrrhula, Linn., 

 the northern bullfinch, is a North European form 

 that visits us sometimes when on migration, and 

 which may be known by its decidedly larger size.)
