529. Gallinula tenebrosa, GouldVol. VI. Pl. 73.

Nearly allied to, and a representative of, the Water-Hen of Europe, Gallinula chloropus.

Genus Fulica, Linn.

Fulicæ are found in nearly every part of the great continents of Europe, Asia, Africa and America, and one species in Australia.

530. Fulica Australis, GouldVol. VI. Pl. 74.

This bird, which is strictly confined to Australia, is rather smaller than its European ally.

Genus Parra, Linn.

A tropical form, the structure of which is admirably adapted for progression over the aquatic plants and floating leaves of the lagoons and inland waters it frequents and over which it passes with facility; its expansive feet, spreading over a large surface of fallen grasses and leaves, readily sustaining it, which they would not do were they of the ordinary form.

Species of this form are found in India, Africa and America.
