“The specimens described above are all from Borneo. Two females in the British Museum from Sumatra, in reddish plumage, are lighter than those from Borneo, being rather of a cinnamon-rufous color. The patches on the lower throat are cream-colored, with a cinnamon-rufous border and a blackish subterminal bar, but without any further blackish bars.
“These differences, however, seem to me not constant after comparing the material in the Leyden Museum; nevertheless, I have not yet heard of any blackish specimens from Sumatra, and it must therefore be left open to question at present whether it is possible to separate the Sumatran and Bornean specimens specifically or subspecifically.” (Hartert.)
