brownish grey, slightly tinged with rufous near the shafts, with | 
from seven to eight moderately broad, transverse, hair brown 
bars, broadest at the tips, where the terminal bar may be nearly 
three-quarters of an inch broad, and narrowest towards the 
bases of the feathers, where they may be about three-eighths of 
an inch; the lateral feathers are similar, but the grey of the inner 
webs is less tinged with brown, and slightly more rufescent. 
The silver grey on the outer webs of the primaries, is replaced 
by ashy brown, and the bright rufous mottling there, and 
tinting of the inner webs of the quills, by dingy rufous buff, or 
dull fulvous. The chin is whitish, the feathers with dull, dark 
brown, central stripes, and the whole of the rest of the lower 
parts a dull uniform umber brown, (in some specimens suffused 
with ferruginous,) the feathers of the breast and upper abdomen, 
narrowly, and not very conspicuously, margined with a dingy 
rufous buff, or pale ferruginous, and the tibial and tarsal plumes, 
and lower tail coverts spotted, or imperfectly barred, with dingy 
fulvous or rufescent white. The axillaries and wing lining, are 
a deep hair brown, more or less mottled, and margined, with 
ferruginous, the amount of which, varies very greatly, in speci- 
mens of this type. 
A third type, has the brown of the upper surface exceedingly 
dark, and the rufous edgings of the feathers more ferruginous ; 
the rump and upper tail coverts deep chocolate brown, with a 
rich purple gloss, and no trace ofrufous edgings. ‘The tail some- 
what as in the last, but much more strongly tinged with ferru- 
ginous, with one huge, terminal, blackish brown band, and above 
this, eight or nine very narrow, and irregular, wavy, transverse 
bars of the same colour, but paling towards the bases of the 
feathers. Below, the whole breast, axillaries, sides, flanks, tibial 
and tarsal plumes intense ferruginous, brightest and most rusty 
on the centre of the breast, deepest and tinged with chocolate 
in the tibial and tarsal feathers. ‘The whole of the abdomen, 
vent, and lower tail coverts, yellowish or rusty white, more or less 
densely banded, or mottled, in twin spots, with deep ferruginous, 
(which in’ some specimens, so far predominates, that it might 
more properly be called the ground colour, and the white the 
barring,) which in some is bright and rusty, and in others 
deep, and tinged with umber, or chocolate. Some specimens 
have the heads paler than I have described, and in these the 
foreheads, an ill-defined streak over the eye, the ear coverts, 
ehin, and throat are nearly pure white, all the feathers, however, 
having dark shafts. Where this is the case, the whole tone of 
colowing is somewhat paler, than I have above described, but 
all the specimens that I have yet examined, are referable to, or
