"Similar to P. atricapilla, but of rather larger
dimensions." (Sclater.)
Writing of Pitta atricapilla and P. mulleri Sharpe [53] says: "These
two birds are closely related; but the Bornean species [mulleri]
almost entirely wants the black patch on the belly, and has the thighs
blackish instead of ochraceous brown."
