ho
consider Australia to have formerly appeared as a cluster of three or
four islands, subsequently connected since the tertiary epoch so as to
form what may now be considered as a continent. With the kind assistance
in determining the species of Mr. Gould, who has elsewhere published
similar lists* of the birds of other parts of Australia, the annexed
Catalogue has been made out. All the species contained therein have
passed under my own observation, and I have distributed them in three
columns; the first includes that portion of the north-east coast of
Australia and its islands included between the Tropic of Capricorn and
latitude 17 degrees 45 minutes south, or the parallel of the bottom of
the Gulf of Carpentaria; the second comprises the remainder of the
north-east coast as far to the northward as Cape York; and the third is
devoted to the islands of Torres Strait, from Raine Islet to Bramble Cay.
The species marked with an ? (query) are those which are probably local
varieties, representatives of southern birds, showing slight differences
in size, etc., yet not decided enough to be of specific value.
