Figure and description. Y^alden II, 1; Shelley 5. 
Adult. Head, neck, ear-coverts, and cheeks rather pale slate-grey; upper surface 
dark rufous brown, the margins of the wings mottled with russet, the rump and upper 
tail-co veils redder and obscurely tipped with grey like the head; metacarpal joint 
white; tail rufou.s brown, brighter than the back, tipped with white and crossed with 
three or four broad bands of black, the interspaces on the more lateral feathers chiefly 
wliite or white mingled with rufous, the middle feathers all rufous brown with a broad 
tenninal band of black and a black spot indicating another band with a small spot 
of wliite adjoining; under surface white, thickly barred with slaty black on dun 
and throat, with purer black across chest, breast,- sides and flanks; under tail- and 
wing-coverts wliite, the latter with a browm spot here and there at the edge of wing 
and on the longer series; quills below broccoli -brown, white towards base (near 
Tondano, Aug. — Sept. 1892 — C 10796). 
“Bill black, at base of lower mandible yellow; bare skin round the eyes gold- 
yellow; feet gold-yellow". Other adult specimens (all marked (^) for the loan of one 
of which we ai'e indebted to Mr. Nehrkorn, while the others are in the Sarasin 
Collection, are like the above. “Iris browm; bill black, below yellow -green; orbits 
and feet light yellow” (Burukan, 2. XI. 84 — Platen in Mus. Xehrk. Xr. 931). 
Immature. Differs from the adult in having the head above brownish slaty; neck and upper- 
surface chestnut (i. o. hghter and redder), some remains of dark bars on the tertiaries 
above; below huffy — not jrure — white, plentifidly barred -with blackish brown, 
except on under wing- and tail-coverts (Miirahassa — Xr. 2207). Tliis is like fig. 2 
of Lord Walden’s plate, but the under surface is more thickly barred. As Captain 
Shelley poiirts out, the tail in tins figure conveys a wTong impression, the two middle 
feathers being lost; there is no white except at the tip on the middle tail-feather 
(there is only one remaining) of our specimen, though the shaft is pale at one spot. 
Young. A younger specimen in the Xehrkorn CoU. (Xr.930 — Eurukan, 10. XL 84: Platen) 
differs from that described in being still paler rufous brown above, Avith the mantle 
indistinctly spotted; below still more thickly baiTed -with black. “Bis brown; bill 
brown, below yellow-green; orbits and feet light yellow”.
