Birds of Celebes: Zostpvopidae. 49 1 



Only a single specimen of this species is known, the type which Mr. 

 Nehrkorn has had the great kindness to lend us. It has close affinities with 

 Z. atrifrons of North Celebes, which differs by its smaller size, by its having the 

 black of the forehead carried a little further towards the crown, the upper sur- 

 face somewhat darker, esi^ecially on the rump and upper tail-coverts, the chin 

 and throat greenish ochre-yellow and notably darker, the breast paler ashy, the 

 bill black instead of brown, the feet lead-grey instead of pale brown. Zosterops 

 nehrkorni, in the opinion of Prof. W. Blasius, is most like Z. chrysolaema Salvad. 

 of the Arfak Mountains of North-west New Guinea, from which it differs in 

 having the breast and sides of the abdomen ashy, the thighs pale yellow, the 

 forehead and anteocular region dusky black, the subocular region green yellowish, 

 and by the colour of the bill and feet.'

 Plate XXXI. 



Zosterops sarasinorum (Ij M. & Wg., J. f. O. 1894, 114; (2j iid., Abli. Mus. Dresd. 1895, 

 Nr. 8, p. 12; (3) iid., ib. 1896, Nr. ), p. 6; (4) Hart., Nov. Zool. 1896, 153; (5) id., 

 ib. 1897, 157. 



Diagnosis. Like Z. palpebrosa (Temm.) of Lidia, but the sides very pale yellowish drab, 

 not grey (see Hartert 5), tlu-oat and jugulum canary-yellow, passing into lemon- 

 yellow on the sides of throat and jugulum, cliin and anterior malar region, this 

 colour being cleai'ly separated from (not blending withj the yellow olive-green of the 

 hind cheeks, ear-coverts and sides of neck; upper surface somewhat yellower olive-green. 



Adult male. Above yellow olive-green, most olivaceous on the wing-coverts and mantle, 

 yellowest on the rumi) and upper tail-coverts; supra-loral region and forehead at 

 base of bill lemon-yellow, passing on the forehead into the yellow olive-green of 

 the crown; orbital ring wliite; a narrow loral streak continued as a line under 

 the orbital ring black; hind cheeks, ear-coverts and sides of neck couco- 

 lorous with the upper siu-face; chin, anterior malar region, sides of throat and 

 of jugulum lemon-yellow, hgliter on the middle of tlu'oat and jugulum; under tail- 

 coverts less pm'e yellow; remaining under-parts white, washed with huffy drab, 

 chiefly on the sides and flanks; under wing-coverts and inner edges of quills 

 below whitish, the foi-mer washed with yellow especially on the metacarpal edge 

 (type, rj', Mount Klabat, circa 6000 ft., N. Celebes, end of September, 1893: Sarasin 

 Collection). 



"Iris sepia; bill above black, base of under mandible bluish; feet and legs 

 slate-coloiu'" (Sarasins). 



Immature male. The yellow on the supra-loral region and forehead much less developed; the 

 yellow of the gidar region much paler and less pure; the upper surface less yellow 

 in tint (rf, Mt. Klabat, c. 6000 ft.: 24.-26. Sept. 1893: Sarasin Collection). 



The original colours of four other specimens from the same point have been 

 destroyed by preservation in alcohol'). 



•) Alcohol works disastrously upou the yellow olive-green tints of ZosU.rops, converting them into greyish 

 ilive, so that specimens so preserved have been mistaken by competent ornithologists for new species.
