Proc. U. S. Nat. Mus. (1909), 36, 443.
Mindanao (Mearns).
"Characters.--Smaller than typical Zosterops goodfellowi, with stouter
bill, front half of head grayish brown instead of olive-green; nape
greenish gray instead of olive-green; auricular patch more sharply
defined and less greenish; malar region washed with brown instead of
being dirty white; throat and upper breast more distinctly washed with
brown. The iris is reddish brown in both; bill black in malindangensis,
plumbeous-black in goodfellowi; feet and claws pale olive, yellowish
on under side of toes in both." (Mearns.)
Genus HYPOCRYPTADIUS Hartert, 1903.
Bill similar to that of Zosterops, but somewhat stouter and ridge of
culmen rounded; colors very different from Zosterops; entire upper
parts cinnamon-rufous and no white eye-ring.
The characters of Hypocryptadius as given by Hartert follow: "Bill
rather higher and comparatively short, the culmen distinctly curved;
nasal groove less than one-third of the length of the exposed portion
of the culmen; culminal ridge more rounded. Wing as in Zosterops
(i. e., 'nine primaried'), the first (developed) primary only 5
mm. shorter than the next and at least 1 1/2 cm. longer than the
secondaries. Larger than Zosterops, coloration different from all
Zosteropidæ. Sexes alike. Feet very strong, but structurally similar
to those of Zosterops."
