Birds of Celebes: Cuculidae. 
Adult. Upper surface (except head and neck) dark drab, the feathers of back, upper tail- 
and wing-coverts broadly terminated with hlacldsh brown, terminal portion of quills 
blackish brown; tail crossed by a broad subferminal band (70 mm wide) of black, the 
lateral feathers marked on the inner webs with narrow bars of black, longest on the 
outermost pair, but generally not reaching to the shaft, the interspaces chiefly filled 
with pale cinnamon, tip of tail white, broadest (ca. 30 mm) on the lateral feathers; 
entire bead and neck uniform cinereous, a little paler on chin and throat, be- 
coming light grey with a pink wash on the breast, on which are very faint traces 
of bars; rest of under surface with a wash of huh;, the bars becoming more 
distinct, especially on the flanks and under tail - coverts , where they are, light drah- 
hrown (nr. Manado, Aug. — Sept. 1892, 0 10868). “Iris cherry-red; skin round eyes 
cherry-red; hill whity grey, darker at root; feet lead-grey” (Platen 19). 
In another specimen, probably older, marked Celebes — Riedel, Nr. 14009, the 
bars on the under surface are discernible only on the flanks, thighs and under tail-coverts. 
Sexes. They are similar in plumage (Shelley 26). Prof. W. Blasius (19) believes that the 
male has “a very considerably longer hill, with the point more strongly curved; a 
larger size in general, the colour of the upper surface somewhat darker, the barring 
of the under surface scarcely perceptible”. Mr. Hartert draws attention to a female 
which is larger than a male specimen (31). 
Young. The cinereous of head, neck and breast of adult is chiefly occupied with feathers 
of pale cinnamon; hack, wing-coverts and tail-coverts broadly terminated with 
pale cinnamon, usually preceded by a subfer mi nal bar of blackish; ends of wings 
pale cinnamon and wliite; the broad white tip of tail washed with the same colour, 
the lateral tail-feathers mottled with bars of j)ale cinnamon and black on the outer 
as well as the inner webs; under surface deeper buff colour, the bars of drah- 
hrown very distinct (N. Celebes — Riedel, Nr. 14010). “Iris light brown; skin round 
eyes cherry-red; hill whity grey, not darker at the base” (Platen 19). 
A somewhat older immature bird differs from the above in that the cin- 
namon tips of the feathers are fewer, narrower, and paler, being almost pure Avhite 
on the quills and tail (Celebes, C 3580). 
Egg. Dull white, with faint washed-out pinldsh spots and minute dots, also some of a 
yellowish brown tinge. Size 38x27 mm (North 25). 
Breeding season in Australia. November (North 25).
