second the inner webs are marbled with brown^ as in the 
earliest stage of plumage, but are not barred : the new secon¬ 
daries and tertials are all a plain unbarred rufous on their 
inner webs, as are the primaries also ; the central pair of rec- 
trices are wanting, the remainder, which have not yet been 
moulted, are barred like the unmoulted secondaries and ter¬ 
tials. This specimen has lost the immature fulvous tips to 
the wing-coverts, and also wants the nuchal strise which are 
apparent in F, which, with the above exceptions, it closely 
resembles. 
H, Togian Isles, Celebes. This specimen, as regards the 
shaft-marks, resembles F, with the exception of those on the 
rufous mantle being rather less strongly marked, and those 
on the breast being less numerous; it appears to be fully 
adult, but the inner webs of the secondaries and tertials are 
transversely barred with brownish black*. 
I, from Morty Island. An adult specimen entirely desti¬ 
tute of dark shaft-marks on the white portions of the plu¬ 
mage, and with those on the rufous mantle not very con¬ 
spicuous, and in many of the feathers of a dark-rufous colour 
rather than black; this bird shows no dark transverse bars, 
except a few very imperfect traces on some of the primaries 
of one wing only. 
J, from Gilolo. An adult specimen, imperfectly marked 
with dark transverse bars on the inner webs of all the quill- 
feathers of the wings and tail, except the central rectrices, 
the shaft-marks rather strongly marked on the rufous mantle, 
but entirely absent from all the white portions of the plumage. 
K, from Batchian. Apparently an old bird, resembling J 
in all respects, except that the shaft-marks on the rufous 
mantle are less strongly marked, and that there are no traces 
of cross bars on the quill-feathers of the wings or tail, except 
a single spot which remains on the inner web of one of the 
lateral rectrices. 
L, from North Ceram. This specimen entirely resembles 
K, except that the tail is wholly immaculate. 
The Celebean race was supposed to be distinct by the late Dr. F. 
Briigg’emann, who proposed for it the subspecific name of amhiguusr
