Goodfellow’s silvereye is a very distinct species of entirely different coloration from any of the preceding species. It is known only from Mount Apo, Mindanao.

621. ZOSTEROPS MALINDANGENSIS (Mearns).
MALINDANG SILVEREYE.

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 1½ 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.”
