130 Mr. R. Hall on Birds 
remains one of the few Australian birds' eo:gs not yet described 
in scientific literature. The clutch is composed of three eggs_, 
one being deposited each successive day. A nest found at 
Katanning was built with three walls : {a) external^ bark ; 
(b) thin middle, grass-stems and horsehair ; {c) internal 
layer, animals' brownish-red hair. Slightly oval in shape, its 
greatest diameters were 3 inches X 2*5 inches ; the bowl- 
diameter was half an inch less, while its depth was 1*5 inch; 
the depth of the whole structure (which tapered to accom- 
modate itself to the fork, 7 feet above the ground, in a 
Casuarina) was 3 inches. A much more beautiful and broader 
nest is exhibited in the Perth Museum. 
Specimen H. — Upper surface brown, each feather streaked 
with white along the mid-rib j lores and base of forehead 
shewing white ; throat a mixture of brown and whitish ; 
chest deep brown ; abdomen white ; under tail -coverts pale 
chestnut ; all the white on the wing-quills of the adult 
represented by rufous ; under surface of wing with a white 
line across the basal part of the quills ; outer tail-feather 
as in adult, except for the measurements ; each tail-feather 
with the rachis extended so as to appear spinose; bill and 
feet lemon-coloured ; nails black ; soft ring round eye pale 
yellow ; eyes black. Total length 3*4 inches, wing 2'2. 
Specimen J. — This appears to have left the nest only a few 
days before being killed, and is similar to H, but has larger 
measurements, while the bill is not so yellow. Total length 
4 inches, wing 23. 
Specimen K. — This is very little older than H or J. The 
upper mandible is maturing into black, and the rufous of the 
wings is becoming white; there is more white on the fore- 
head than in H or J, and it is now becoming a definite 
frontal mark; feet below rich orange, above light orange. 
Total length 4"55 inches, wing 2'75. 
Specimen M. — A great change is now being effected in the 
plumage. No red appears in H, J, K, but here we have an 
outburst of not only " reds," but " blacks '' and " whites,'' 
a large proportion of the streaked feathers of all stages being 
still retained in the dorsal region.
