regularly to water night and morning, when
it was so dark that they could hardly be seen. The plumage of this bird
is very beautiful. Its back and neck are green, as well as the crown of
the head; its wings blue black; the breast and under tail feathers are of
a bright yellow, with a blue and yellow band in the front.

91. EUPHEMA BOURKII.--Bourke's Parroquet.

This elegant little bird was also a visitant at the Depot, and remained
throughout the winter; keeping in the day time in the barren brushes
behind the camp, and coming only to water. The approach of this little
bird was intimated by a sharp cutting noise in passing rapidly through
the air, when it was so dark that no object could be seen distinctly; and
they frequently struck against the tent cords in consequence. This
Euphema has a general dark plumage, but with a beautifully delicate
rose-pink shade over the breast and head, by which it will always be
distinguished.

92. MELOPSITTACUS UNDULATUS.--Warbling Grass Parroquet.

Called "Bidgerigung" by the natives. This beautiful little Euphema visits
South Australia about the end of August or the beginning of September,
and remains until some time after the breeding season. It is perhaps the
most numerous of the summer birds. I remember, in 1838, being at the head
of St. Vincent's Gulf, early in September, and seeing flights of these
birds, and Nymphicus Novoe-Holl. following each other in numbers of from
50 to 100 along the coast line, like starlings following a line of coast.
They came directly from the north, and all kept the same straight line,
or in each other's wake. Both birds subsequently disperse over the
province. The plumage of this bird is a bright yellow, scolloped black,
and three or four beautiful deep blue spots over each side the cheek.

93. NYMPHICUS NOVAE-HOLLANDIAE.--The Crested Parroquet.

One of the most graceful of the parrot tribe, coming in, as I have stated
above, with the Melopsittacus, and remaining during the summer. The
general plumage is grey, with a white band across the wings. It has also
a sulphuryellow patch on the cheek, in the centre of which is one of
scarlet. It has also a long, hairy crest, which it keeps generally
erected. Both birds passed the Depot in migrating, and Nymphicus was the
last bird we saw to the north of the Stony Desert, in lat. 24 1/2 degrees
and long. 138 degrees, on its return to the province in September.
