A single specimen (Q) obtained on Mount Liang Koe- 
boeng. — This bird fully agrees with the description of the 
typical specimen, which was hitherto the only one known 
to represent this species, and is therefore new to Borneo. — 
It is a true jungle-bird, and was shot in thick rattan- 
jungle, close to the ground. — Iris red, bill horny gray, 
lower mandible reddish at the base, feet greenish gray. 
Hab. Johore (in the southernmost part of the Malay
