A SUPPLEMENT TO THE BIRDS OF AUSTRALIA. 
Such a work as the ‘ Birds of Australia’ could not be kept incomplete 
for an indefinite period; it was, therefore, brought to a close in 1848, 
when all the species then known had been figured; but as Australia be- 
came more and more known, additional species of birds were discovered, 
rendering a Supplement necessary, in order to keep the subject complete. 
Parts I, IL, IIL, IV., and V., price £3 3s. each, have been published as 
a sufficient number of novelties came to hand; and with Part V. Titles 
and every requisite to form the whole into a Volume have been fur- 
nished. This Supplementary Volume, containing many novelties of the 
highest interest, the Author considers to be one of the most important he 
has produced, whether regarded as a continuation to the seven volumes 
which preceded it, or as a separate work. Price 15 Guineas. 
A HANDBOOK TO THE BIRDS OF AUSTRALIA. 
This work has been published in consequence of the Author having been 
led to believe that a résumé of the subject in an 8vo form, without 
Plates, would be acceptable to the possessors of the folio edition, as well 
as to the many persons in Australia who are now turning their attention 
to the Ornithology of the country in which they are resident, and because 
he was moreover assured that such a work was greatly needed to enable 
the explorer during his journeyings, or the student in his quiet home, to 
identify the species that might come under his observation, and as a 
means by which the curators of the museums, now established in all 
parts of the world, might arrange and name the Australian birds entrusted 
to their charge; and he believes that the two volumes (containing over 
600 pages each) in which it is comprised will fully answer the desired 
end. 
The price of the Two Volumes, which contain a considerable amount 
of additional and interesting information, and many species not in the 
folio edition, is £2 10s, 
VY. THE BIRDS OF ASIA. Jn course of publication. 
To no portion of the globe does there attach so much interest as to that 
vast extent of the Old World which we designate Asia. It is there that 
all the productions of nature essential to the well- being of man occur in 
the greatest abundance. ‘The most important of our domestic quadrupeds, 
the most valuable and interesting of our domestic Gallinaceous birds, 
were first reclaimed in Asia. It is in Asia that animal life exhibits in its 
forms the highest degree of organic development, together with a variety 
in those forms in accordance with the varied physical characters of this 
extensive region, where the grandest mountain-ranges alternate with 
steppes, sandy deserts, inland seas, and interminable ‘forests of gigantic 
growth. That the Zoology, then, of such a country should have called 
forth the notice and study of able minds cannot be surprising; and yet 
it is remarkable that no one has attempted a work comprehending a 
general history of its OrnirHoLoGy. This hiatus in Ornithological 
literature the Author proposes to fill up by publishing a work on “The 
Birds of Asia,’ precisely similar in every respect to his former works on 
‘The Birds of Europe’ and ‘ The Birds of Australia.’ Its size and manner 
of execution will be the same; and it will be published in Parts, price 
Three Guineas each. 
Of this work twenty-five Parts have been published up to 1873; and for 
the present it will still appear at the rate of not more than one or two 
Parts a year.
