One example marked a female, Deering Creek. This specimen differs from 
any female I had previously seen of this species, and is similar to a semi-adult 
male in the reference collection of the Australian Museum in having the chestnut 
colouring of the upper surface extending all over the back and rump. On the 
under surface it resembles the female in having the throat and chest gi’ey, instead 
of blue-black, and in being destitute of the line of black streaks on the feathei-s 
separating the white breast and abdomen from the brown flanks. Another semi¬ 
adult male in the Australian Museum collection, from the western district of 
New South Wales, shows a further advance towards maturity by having the grey 
feathers of the throat and chest intermingled with others of a glossy blue-black. 
If the specimen obtained by Mr. Keartland is really a female it is probalily a very 
old bird and cannot be distinguished from the immature male. I believe it to be 
a young male. 
[I was only successful in securing one female of this species, and with the 
exception of one afterwards seen at Hermannburg, this was all we saw. The 
specimen obtained was peculiar from the fact that instead of confining itself to 
the ground like most members of the genus, it flew from bush to bush and was 
eventually shot on a branch fifteen feet from the ground.]

Two examples of this distinct and well-marked species obtained at Glen 
Edith. Both are males and are apparently not quite adult, or in the moult, for 
one has only a faint indication of the beautiful lilac nuchal plumes, and they are 
but slightly more developed in the other specimen. This species is readily dis¬ 
tinguished from its near ally C. maculata, of eastern and southern Australia, by 
the feathers of the upper surface being blackish-brown instead of dark brown— 
rendering the spots, which are paler, more conspicuous—and by the absence 
of the earthy-brown band between the nuchal plumes and mantle. The head and 
neck, too, are much darker, and the tips of the wing-coverts and secondaries are 
pale yellowish-buff instead of tawny-buff. 
[Wherever the “native fig” trees existed these birds were found. They were 
generally very shy, and only two specimens were obtained. Several bowers seen
