Tah-gó-saa or tah-go-say'-ahn, Bagobo; tar-man'-op, Moros of Pantar and Lake Lanao.

Mindanao (Mearns).

"Adult male and female.--Similar to Macronous mindanensis mindanensis, but very much darker with heavier markings throughout; the dark shaft-streaks are increased in area and intensity; the blackish feathering of the upper side of the head occupies more of the nape; and the back and rump are prout's brown instead of raw umber; the under parts are dark from the throat backward, the flanks being dark isabella instead of clay-color. This mountain form (from Pantar at 610 meters and Mount Apo at 1,220 meters) is slightly smaller than the subspecies mindanensis. It is still farther removed from Macronous striaticeps Sharpe from the Island of Basilan." (Mearns.)
