DUTCH BORNEO-EXPEDITION. 231 



olive, the tail-feathers as well as the upper and lower tail- 

 coverts are much browner than in the other two species. 

 Hab. Restricted to Borneo, where it is not so generally 

 distributed as C. (jutturalis, 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. rujicrissus 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 Liaug 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.
