ch was secured. They
generally rested on a high pointed rock, whence their glance extended
over the whole country, and it was only by accident that the above
specimen was killed.

This powerful bird is common both on the Murray and the Darling, and is
widely, perhaps universally distributed over the Australian continent,
although the two birds in the Glen were the only ones seen in the
interior to the N.W. of the Barrier, or Stanley's Range.

2. HALIASTUR SPHENURUS.--The Whistling Eagle.

This species of Eagle is considerably smaller than the first and has much
lighter plumage. It is a dull and stupid bird, and is easily approached.
It was shot at the Depot, in the month of April, 1845. Several others
were seen during our stay there.

3. FALCO HYPOLEUCUS, GOULD.--The Grey Falcon.

This beautiful bird was shot at the Depot, at which place, during our
long stay, Mr. Piesse, my storekeeper, was very successful with my gun. A
pair, male and female, were observed by him one Sunday in May, whilst the
men were at prayers, hovering very high in the air, soon after which he
succeeded in killing both. They came down from a great height and pitched
in the trees on the banks of the creek, and on Mr. Piesse firing at and
killing one the other flew away; but returning to look for its lost
companion, shared its fate. Nothing could exceed the delicate beauty of
these birds when first procured. Their large, full eyes, the vivid yellow
of the ceres and legs, together with their slate-coloured plumage, every
feather lightly marked at the end, was quite dazzling; but all soon faded
from the living brightness they had at first. The two specimens were the
only ones seen during an interval of seventeen months that the party was
in the interior, and these, it appears probable to me, were on the
flight, and were attracted down to us.

4. FALCO MELANOGENYS, GOULD.--The Black-cheeked Falcon.

A single specimen of this bird was shot at the Depot, when just stooping
at a duck on some water in the glen. The strength of limb, and muscle of
this fine species of falcon were extremely remarkable, and seemed to
indicate that he despised weaker or smaller prey than that at which he
was flying when shot. He had been seen several times before he was
killed. His flight was rapid and resistless, and his stoop was always
sure.

This must be a scarce bird, as the specimen was the only one seen.

5. FALCO SUBNIGER, G. R. GRAY.--The Black Falcon.
