MALINDANG SILVEREYE, 
Zosterops goodfellowit malindangensis MEARNS, Proc. U. 8. 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, plum- 
beous-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 14 cm. longer than the secondaries. Larger 
than Zosterops, coloration different from all Zosteropide. Sexes alike. 
Feet very strong, but structurally similar to those of Zosterops.”
