found when no other birds were to be seen.
They generally sat on dead branches, and their flight extended no farther
than from the one to the other.

25. PARDALOTUS STRIATUS, TEMM.--Striated Pardalote.

There are several species of this beautiful tribe of little birds, but
the above was the only kind procured. The species under consideration
occupies the higher branches of the gum-trees, and is so small that it is
seen with difficulty.

26. GYMNORHINA LEUCONOTA, GOULD.--The White-backed Crow Shrike.

This bird is somewhat larger than, and very much resembles a magpie, but
the proportion of white is greater, and there is no metallic or varied
tint on the black feathers as on the European bird. In South Australia it
is a winter bird, and his clear fine note was always the most heard on
the coldest morning, as if that temperature best suited him. All the
species of this genus are easily domesticated, and learn to pipe tunes.
They are mischievous birds about a house, but are useful in a garden. I
had one that ranged the fields to a great distance round the house, but
always returned to sleep in it.

27. CRACTICUS DESTRUCTOR.

This bird has the strong, straight, and hooked bill. He is an ugly brute
in shape and plumage, but is a magnificent songster. His own notes ring
through the wilds, and there is not a bird of the forest that he does not
imitate. One of these birds regularly visited the camp at Flood Creek
every morning to learn a tune one of the men used to whistle to him, and
he always gave notice of his presence by a loud note of the most metallic
sound. It breeds on the hills, and is generally found wherever there is
shade and water.

28. GRALLINA AUSTRALIS.--Pied Grallina.

This harmless bird, somewhat larger than a field-fare, is found near
water, where the banks are muddy. It is common on all the river flats,
and lives on insects. Its pied plumage is very pretty, but its note is a
melancholy one. Very few were seen to the westward of the Barrier Range,
and those always close to lagoons.

29. GRAUCALUS MELANOPS.--Black-faced Graucalus.

The colour of the plumage of this bird is that of slate, and it has a
black throat. Its range is very extensive, but we did not see it in the
distant north-west interior.

30. PTEROPODOCYS PHASIANELLA, GOULD.--Ground Grauculus.

There were not more than six or seven of this bird seen during the
progress of the Expedition, and that only at the Depot. They were
