“This bird,” says Captain Sturt, “ appeared suddenly in South Australia in 1840. It came from the north, 
fresh flights coming up and pushing on those which had preceded them. It was moreover evident that they had 
been unaccustomed to the sight of man, for they dropped in great numbers in the streets and gardens of Adelaide 
and ran about like fowls. At last they mcreased so much in number as to swarm on all the waters and creeks, 
doing great damage to the crops in their neighbourhood. They took the entire possession of the creek near my 
house, and broke down and wholly destroyed about an acre and a quarter of wheat as if cattle had bedded on it. 
They made their first appearance in November, and left in the beginning of March, gradually retiring northwards 
as they had advanced.” 
Genus GauuinuLa, Briss. 
The true Gallinule are very numerous, and are found in nearly every part of the world. Australia is mha- 
bited by a species peculiarly its own, distributed over all the southern parts of the continent.

species in Australia.
