"Adult male and female (seven specimens).--Upper parts, including
entire top and sides of head, ashy brown tinged with olive; upper
tail-coverts browner; sides of neck yellowish olive; tail-feathers
drab, subterminally and broadly banded with blackish, tipped with
drab-gray, and with a white spot near the end of the inner web of all
[each of] the tail-feathers except the innermost pair; wing-coverts
like the back; quills darker brown and narrowly edged with olive; whole
under parts straw-yellow except the crissum which is almost white;
lining and edge of wing yellowish white; thighs mixed straw-color
and olive-brown; inner edge of quills whitish. Measurements of male:
Wing, 50; tail, 39; culmen, 10.5; tarsus, 16." (Mearns.)
A female from Zamboanga is the only example of this species examined by
me. In this specimen the crown is slightly darker than in specimens of
G. simplex from Mindoro, Luzon, and Lubang with which I have compared
it. Unfortunately Mearns does not compare his species with G. simplex
which is probably its nearest relative. Guillemard records a gerygone
from Sulu as G. flaveola, and his specimens were, perhaps, the same
as G. rhizophoræ.
Genus ZANTHOPYGIA Blyth, 1847.
Bill at nostril slightly broader than deep, slightly compressed toward
the tip; rictal bristles moderate, extending half the length of bill;
tarsus twice the length of bill from nostril; wings moderate in
length, when folded extending nearly to tip of tail; first primary
much less than one-half the length of second, the latter less than
third and fourth which are subequal and longest; tail square and equal
to two-thirds of wing. Sexes very different in colors, the colors of
the male are yellow, black, and white.
