olive, the tail-feathers as well as the upper and lower tuil- 
coverts are much browner than in the other two species. 
Hab. Restricted to Borneo, where it is not so generally 
distributed as C. gutturalis, but rather an inhabitant of the 
hilly regions than of the plains and coast regions. It is a 
rather strange fact that two so closely allied species as 
C. gutturalis and C. ruficrissus were both found together 
at the same time in the forests of the Liang Koeboeng.

A great number of specimens collected at the foot and 
on the slopes of Mount Kenepai, on the western slope of 
the Liang Koeboeng, at Nanga Raoen and in the Sibau 
valley; also from Long Bloe on the Upper Mahakkam. It 
is an inhabitant of low and high forest, — Iris brown, 
bill horny gray, feet yellow. 
Males and females do not differ in size and color. Birds 
in transitional stage of plumage have the secondaries strongly 
margined with rufous. A nearly fledged nestling, obtained 
on Mount Liang Koeboeng, differs remarkably in having 
the upper surface, especially the secondaries and wing- 
coverts, russet brown instead of olive-green, the crown 
olive-brown instead of ashy gray, the throat yellow instead 
of pure white, the chest olive-green instead of ashy gray, 
and the rest of the lower surface pale sulphur-yellow. Al- 
though the plumage is quite downy, the long nuchal hairs 
are already strongly developed. 
Hab. Restricted to Borneo, where it seems to be distri- 
buted over the whole island.
