"Chafacters. 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 HYPOCEYPTADIUS 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 Hypo cry ptadius 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 Zoaterops (i. e., 

 'nine primaried'), the first (developed) primary only 5 mm. shorter 

 than the next and at least 1J cm. longer than the secondaries. Larger 

 than Zosterops, coloration different from all Zosteropidce. Sexes alike. 

 Feet very strong, but structurally similar to those of Zosterops."
