DUTCH BORNEO-EXPEDITION. 253 
An adult male, from Pontianak, an adult male and female, 
both similar in color, obtained in May at Nanga Raoen, 
an immature male with red tail but the red on the head 
not yet fully developed from Smitau (Dec. 9th) and a young 
male from Poelau, Sibau R. (April 15th), Four specimens 
from the Upper Mahakkam. The specimen from Poelau 
has, in strong contrast to the adult birds, the upper sur- 
face olive-green and the white lower surface, and especially 
the sides of head and neck, very strongly washed with yellow. 
A few red feathers are making their appearance on the 
olive-green crown, while on the tail the red color is more 
strongly developed. — The iris in the adult birds is brick- 
red, the upper mandible brown, the lower whitish, feet 
pale flesh-color; in the young bird the iris is gray, the 
lower mandible yellow. 
This species is found round the native settlements, very 
often together with the following species. In the jungle 
and high forest it was never observed. 
Hab. The lndo-Malayan region, Java excepted, and the 
Philippines. In Borneo it seems to be a rather common 
bird over the whole island.
