Luzon (Whitehead).
"Male and female adult.--In general appearance this new species
resembles Mixornis montana Sharpe, from Mount Kina Balu, but it
is readily recognizable as forming a second species of the genus
Zosterornis by the shape of the nostrils and the peculiar ring of
white feathers which surrounds the eye, as well as the absence of
rufous-brown or dark chestnut on the wings so characteristic of the
genus Mixornis.
"The general color of the upper parts is dull olive, tinged with
brownish on the upper tail-coverts: quills dark brown, edged on the
outer web with olive, and on the inner with yellowish white. A marked
ring of white plumes surrounds the eye; lores and fore part of cheeks
whitish, tinged with yellow; a well-marked black eyebrow stripe from
the nostril to the posterior margin of the orbit, and a second less
distinct band below the eye; hind cheek and ear-coverts dull olive
like the crown; chin and throat uniform white, tinged with yellow and
bordered on either side by a black malar stripe; rest of the under
parts yellowish white, each feather with a wide black shaft-stripe;
tail-feathers brown, margined with olive towards the edges of the
outer webs.
"Types of the species.--Male adult: Length, 140; wing, 60; tail, 52;
tarsus, 18; culmen, 16. Female adult: Length, 140; wing, 61; tail,
52; tarsus, 18; culmen, 16." (Grant.)
The striped tree babbler is known only from the mountains of northern
