 steel-blue, central rectrices tinged with bronze ; bill black. Total

 surface white, each feather with a bright green discal spot ; lateral 

 rectrices tipped with white. 



Youufj males have rufous throats ; the blue gular spot is deve- 

 loped at an early stage, some time before the bright feathers of the 

 crown begin to appear.

 of the same shape as that of the male, but paler. The under surface 

 is normal.
