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

5.  Falco SUBNIGER, G. R. Gray.—­The Black Falcon.

The colour of this fine bird is a sooty black, but his shape is beautiful, and his flight, as his sharp pointed wings indicate, rapid.  He was shot in some brushes behind the Depot, where he had been spreading alarm amongst a flight of parroquets, (Euphema Bourkii).

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

6.  Falco FRONTATUS.—­The White-fronted Falcon.

This is both a smaller and a more common bird; its range being very wide.  This species followed the line of migration, and made sad havoc among the parroquets and smaller birds.  He was generally hid in the trees, and would descend like an arrow when they came to water, frequently carrying off two of the little Amadina castanotis, a favourite bird of ours, one in each talon.

7.  TINNUNCULUS CENCHROIDES.—­Nankeen Kestril.

Like the last, small and swift of wing, following also the line of migration.

This bird is generally distributed over the continent and is known by the nankeen colour of his back.

8.  ASTUR APPROXIMANS, Vig.  And HORSF.  Australian Goshawk.

This bird was occasionally seen during the journey.

9.  Milvus affinis, Gould.—­Allied Kite.

This bird is common over the whole continent of Australia.  They are sure to be in numbers at the camps of the natives, which they frequent to pick up what may be left when they go away.  They are sure also to follow any party in the bush for the same purpose.  About fifty of these birds remained at the Depot, with about as many crows, when all the other birds had deserted us; and afforded great amusement to the men, who used to throw up pieces of meat for them to catch in falling.  But although so tame that they would come round the tents on hearing a whistle, they would not eat any thing in captivity, and would have died if they had not been set at liberty again.  It was this bird which descended upon Mr. Browne and myself in such numbers from the upper regions of the air, as we were riding on some extensive plains near the Depot in the heat of summer.  There can be no doubt but that in the most elevated positions where they are far out of the range of human sight, they mark what is passing on the plains below them.  This bird is figured, see page 269, Vol. 1.

10.  Elanus SCRIPTUS, Gould.—­The Letter-winged Kite.

This beautiful bird was first seen on a creek to the eastward of the Barrier or Stanley’s Range, and before the party had crossed that chain of hills.  One was shot on the advance of the Expedition from the Darling in the early part of November 1844, in latitude 32 degrees, and on the return of the party from the interior, in December 1845, several specimens were seen as low as Cawndilla, and ranging along the
