254 BIRDS OF THE 
Mt Liang Koeboeng (780 m.) and Poelau. Five specimens 
were also obtained by Dr. Nieuwenhuis in the winter 1898— 
99 on the Upper Mahakkam. — Iris brownish orange, bill 
flesh-color, culmen dark brown, feet pale flesh-color. 
This species has a rather wide distribution, as it is re- 
corded from Malacca, Sumatra and Billiton, and seems to be 
spread over the whole island of Borneo. From Java it is 
not mentioned in literature, but the Leyden Museum con- 
tains three specimens bearing »Java” on their labels. It is 
a rather curious fact that a specimen was killed as high up 
as my station on the slope of the Liang Koeboeng, the 
nearest human habitations being far off from this place at 
the bottom of the valley.

yellow. — It frequents the vicinities of settlements, where it
