(Platen). 
I have ventured to unite P. discurus of Balabac 
(Sharpe, loc. cit), to P. cyaniceps because immature 
birds of the latter might easily be confounded with 
the former species, and because it seems improba- 
ble in the highest degree that P. disewrus of the 
Philippines should occur in Balabac, seeing that 
there exists a local representative form in Palawan. 
According to Mr. Whitehead the blue crown is 
present only in the mature males of P. cyaniceps.
