deed heart and soul in the result, and
no one would have felt so proud of my success as my much-lamented and
best friend James Chambers. To Mr. John Chambers I am also under many
obligations for assistance in many instances, and I hereby tender him my
best thanks.

I have the honour, etc.,

J.M. STUART.

ON A COLLECTION OF BIRDS FROM CENTRAL AUSTRALIA.

BY JOHN GOULD, F.R.S., ETC.

The Board of Governors of the South Australian Institute having
liberally forwarded for my inspection a selection from the
ornithological collection made by Mr. Frederick G. Waterhouse during Mr.
Stuart's late Exploratory Expedition into Central Australia, I have
thought the matter of sufficient interest to bring these birds under the
notice of the Society, the more so as it will enable me to make known
through our Proceedings a new and very beautiful species of Parrakeet
pertaining to the genus Polyteles, of which only two have been hitherto
known. Every ornithologist must be acquainted with the elegant
P. melanurus and P. barrabandi, and I feel assured that the acquisition of
an additional species of this lovely form will be hailed with pleasure.
The specific appellation I would propose for this novelty is alexandrae,
in honour of that Princess who, we may reasonably hope, is destined at
some future time to be the Queen of these realms and their dependencies,
of which Australia is by no means the most inconspicuous.

Polyteles alexandrae, sp. nov.

Forehead delicate light blue; lower part of the cheeks, chin, and throat
rose-pink; head, nape, mantle, back, and scapularies olive-green; lower
part of the back and rump blue, of a somewhat deeper tint than that of
the crown; shoulders and wing-coverts pale yellowish green; spurious wing
bluish green; external webs of the principal primaries dull blue,
narrowly edged with greenish yellow; the remaining primaries olive-green,
edged with greenish yellow; under wing-coverts verditer-green; breast and
abdomen olive-grey, tinged with vinous; thighs rosy red; upper
tail-coverts olive, tinged with blue; two centre tail-feathers bluish
olive-green; the two next on each side olive-green on their outer webs
and dark brown on the inner ones; the remaining tail-feathers
tricoloured, the central portion being black, the outer olive-grey, and
the inner deep rosy red; under tail-coverts olive; bill coral red;
