87.  Platycercus ADELAIDIAE, Gould.—­The Adelaide Parroquet.

This fine and beautiful bird is common in South Australia, where it usurps the place of the Lory (Platycercus penantii) in New South Wales, and does equal mischief to the stack-yard.  Its general plumage is yellow, but it has a dull red head, and blue cheeks.  Its wings and tail, which is very long, are also blue, the longer feathers being almost black.  Its back is marked with black scollops, and in size exceeds many of the Platycerei.

88.  Psephotus haematogaster, Gould.—­The Crimsonbellied Parroquet.

This Parroquet is a bird of the interior, and was spread over the whole of it in greater or less numbers.  Always numerous where box-trees were growing in the vicinity of water.  The Psephotus haematogaster is essentially a bird of the central parts of Australia, or else its range is confined between the 24th and 30th parallels of latitude.  It is not a bird of bright plumage; it is distinguished by a bright crimson belly.  It has likewise feathers of a peculiar bronze and yellow on the wings; the rest of the plumage being a dull blue green, excepting that over the bill it has some light blue feathers.

89.  Psephotus HAEMATONOTUS, Gould.—­Red-rumped Parroquet.

This is a bird of the interior, and was found on the most distant creeks, amongst the gum-trees.  It was, however, fond of being on the ground, from whence it would rise and hide itself on being alarmed.  It is a wild bird, and a noisy one.  It colours are generally dull.

90.  Euphema elegans.—­Grass Parroquet.

This beautiful Euphema is seen in great numbers on the sea-skirts of the plains of Adelaide, feeding on grass seeds.  It was in course of migration when we were at the Depot in lat. 29 degrees 4 minutes; but after the other birds, and remained stationary for some time.  It was never seen by us in the day time, but came 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.
