590 Bii"Js oi Celebes: Oriolidae. 



Adult. Deep lemon-yellow; a broad fillet passing from lores, above and below the 

 eye, round the nape, black; bastard-wing and remiges black, the primary co- 

 verts broadly tipped \vith yellow, forming a speculum, the secondaries shghtly tipped 

 with yellowish; rectrices black, tipped with yellow, about I cm broad on the middle 

 pair, increasing to 4 or 5 cm on the outermost: "ms deep cinnabar-red; bill white, 

 tinged with rosy red; feet dark olivaceous grey" — Everett 2 (rf, Djampea, Dec. 

 1895: Everett — 1.4878). 



Sexes. The sexes are alike (Hartert 2). Two females in the Sarasin Collection from 

 Bonerate have the upper parts washed with ohvaceous orange. 



Individual variation. "The colour is a pure and perfect orange in some specimens; in others 

 some feathers are orange, others yellow; in some the whole plumage is washed with 

 yellow, while others are of a pui'e lemon-yellow mthout a shade of orange, and of 

 the latter some have the mantle faintly tinged with greenish. These variations in 

 colour are either due to age or perhaps to food, but not to sex or locaUty, specimens 

 from Kalao being perfectly similar to those from Djampea" (Hartert). 



Measurements. Wing 162 — 173 mm; tail 123 — 133 (Hartert evidently measures from the 

 root, we fi'om the oil-gland); tarsus 26 — 29; culmen 36 — 38 fHartert 2). 



Distribution. Bonerate (P. &F. Sarasin 1); Djampea and Kalao (Everett 2]. 



The type of this large Oriole is a female obtained by the Sarasins in 

 Bonerate Island in December, 1894; they subsequently acquired two more speci- 

 mens from the same island, and Mr. Everett a series from Djampea and from 

 Kalao, where he found it more numerous than in Djampea. The nearest known 

 affinities of this bird are with O. hroderipi Bp. of the Lesser Sunda Islands, a 

 smaller species, with a less stout bill, the primaries as well as the secondaries 

 tipped with yellow. There is an error in the description of the type of O. 

 boneratensis ; the middle rectrices are not entirely black, but tipped with yellow, 

 though the yellow tip is broken off in one feather and the other is not full 

 grown; herein it resembles O. hroderipi. The Celebes Oriole is easily distinguish- 

 able from the present bird by its small size, absence of the speculum, etc.; 

 the Sula, Talaut, and Sangi birds by their black heads, with only the forehead 

 yellow, and by other points.
