This species is known from Malacca, Sumatra and Borneo. 
From this latter island it was unknown until a few years 
ago, when it was found by Mr. Everett on M+ Penrisen, 
and by Mr. Hose on Mt Dulit, Mt Kalulong and Mt Mulu.

Liang Koeboeng. Also from the Upper Mahakkam. — Ivis 
pale yellow, bill horny white, culmen black on the basal 
three thirds, feet grayish blue, toes underneath ochre.

Liang Koeboeng) has hardly any black stripes on breast 
and belly, while a male from the same locality has the black 
shaft-stripes very strongly developed. — Iris from terra-
