An adult male from Bongao, and adult birds of both sexes

On comparing the series from the Sulu Islands with the 

 specimens of Chibia pectoralis and C. borneensis, I incline 

 to the belief that they should be referred to the latter 

 species, as the breast-spangles are so very much larger in 

 C. pectoralis.
