Two adult males obtained at Tamsui, Taihoku Distr., May 22. 



This subspecies is distinguished from the typical form of the species 

 by the larger bill, which is 16-19 mm., instead of 14-15 mm., long. Both 

 the forms occur in Formosa as well as in southern Japan, though the typi- 

 cal form is the much less commoner of the two.
