462 Mr. J. H. Gurney's Notes on 



are barred, but the new feathers coming up amongst them 

 are not so ; the dark shaft-marks on the rufous mantle are 

 very black, and more conspicuous than in any other speci- 

 men that I have seen, an effect which is heightened by the 

 faded character of the adjacent plumage. 



C, from Sumatra. This bird, which is adult, only differs 

 from A in having the black shaft-marks on the rufous mantle 

 somewhat less strongly marked, those on the white portions 

 of the plumage, and the transverse bars on the wing, being 

 almost identical in character and extent. 



D, from Banjermassing, South Borneo. This adult speci- 

 men only differs from C in having the dark shaft-marks on 

 the white portion of the plumage rather less distinctly marked, 

 and also in the entire absence of transverse bars from the 

 quill-feathers of the wings and tail. 



E, from Flores. This bird is also adult, and resembles D, 

 with the exception that the shaft-marks on the white portions 

 of the plumage are still less strongly marked, and that slight 

 and imperfect traces of dark transverse bars are perceptible 

 on the inner webs of some of the primaries and tertials. 



F, from Macassar. This specimen has nearly assumed the 

 adult dress, but the feathers of the wing-coverts are still 

 tipped with pale fulvous ; with this exception all those por- 

 tions of the plumage which are rufous in the adult are ru- 

 fous in this specimen, though not quite so intensely as in 

 older birds ; the white portions of the plumage are as in the 

 fully adult bird, and show no admixture whatever, except 

 a few narrow dark shaft-marks on the centre of the crown of 

 the head, and some others on the nape of the neck ; the dark 

 shaft-marks on the rufous mantle resemble those of D ; the 

 inner webs of the rectrices, except the central pair, and also 

 those of the secondaries and tertials, are transversely barred 

 with brownish black. 



G, from Macassar. A moulting bird, which has nearly com- 

 pleted its passage from the immature to the adult dress ; some 

 secondaries and tertials belonging to the former dress still 

 remain ; of these the first are rufous, transversely barred with 

 imperfect transverse brown bands on the inner webs ; in the
