• Count Salvadori has drawn atteution to the difference in the colour of the 

 flanks which exists in a series of this species and also in the red-breasted section 

 of the genus Melaiwhucco, and suggests that the black-spotted individuals are 

 the females. This proposition seems to me to be highly probable.
