noticed on the Barrier Range. The last beautiful little animal
always escaped us in consequence of its extreme agility and watchfulness.

The Native Dog was not seen beyond lat. 28 degrees. Nor was it found in a
wild state beyond Fort Grey, to the best of my recollection; these
miserable and melancholy animals would come to water where we were,
unconscious of our presence, and would gain the very bank of the creek
before they discovered us, rousing us by as melancholy a howl as jackal
ever made; their emaciated bodies standing between us and the moon, were
the most wretched objects of the brute creation.

The first Choeropus castanotus seen, was on the banks of the Darling, in
the possession of the natives, but it was too much injured to be valuable
as a specimen. A second was also killed there, but torn to pieces by the
dogs. None were afterwards seen until after the Barrier Range had been
crossed, when about lat. 27 degrees several were captured alive, as
detailed under the head Dipus. In like manner the first nest of the
"Building Rats" (Mus conditor, Gould) was found in the brushes on the
Darling, where they were numerous. The last nest of these animals was on
the bank of the muddy lagoon to the north of the Pine Forest, in which
the party were so embarrassed, at the end of 1844.

The first Hapalotis, seen was in lat. 29 1/2 degrees on some plains to
the eastward of the Depot, where it was nearly captured by Mr. Browne. A
second was taken by Mr. Stewart, at the tents, but in neither places were
they found inhabiting the same kind of country as that in which they were
subsequently found in such vast numbers. Mr. Gould thinks there were two
species amongst those brought home, and it may be that these two were
different from those inhabiting the sand hills: they only differed,
however, in a darker shade in the fur, and a reddish mark on the back of
the ears.

There were both rats and mice in the N.W. interior, numbers of which took
up their abode in our underground room at the Depot, but there was no
apparent difference between them and the ordinary rat or mouse.

There was only one Opossum killed, or indeed seen to the westward of the
Barrier Range, nor do they appear to inhabit the interior in any numbers.
Since there were no signs of the trees having been ascended by the
natives in search of them.
