254 BIRDS OF THE 



M^ 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 ofi from this place at 

 the bottom of the valley.

 Nanga Raoen, Poetoes Sibau, Poelau and the Upper Ma- 

 hakkam. — Iris brown, bill black (in young specimens 

 yellow), feet and claws flesh-color, in some specimens wax- 

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

 is found in low brushwood and alang-alang fields. 



H a b. This species is restricted to Borneo, where it seems 

 to be spread over the whole island.
