Genus Parra, 
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 faci- 
lity ; 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. 
531. Parra gallinacea, Temm Vol. VI, PI. 75. 
Inhabits the northern parts of Australia and New Guinea. 
Genus Rallus. 
We have here again a genus of birds the range of the species of 
which is most extensive, for there is no country in which one or 
other of them is not to be found.

Genus Eulabeornis. 
Generic characters. 
Bill longer than the head, nearly straight, but slightly curved 
downwards ; compressed laterally ; nostril long and open, situated 
in a large groove which runs along the upper mandible for nearly 
two-thirds of its length from the base ; wings rather short and 
feeble, very much rounded ; tertiaries long, nearly reaching to the 
end of the wing ; legs rather long, more powerful than in the genus 
Beilins; toes not so much lengthened as in that genus; tail long 
cuneiform ; the webs loose and of a decomposed character. 
A genus established for the reception of a singular species of Rail 
inhabiting the north coast of Australia, and in which Mr. G. R. Gray 
has since placed four other species from different localities. 
534. Eulabeornis castaneoventris, Gould . . . Vol. VI. PL 78. 
Genus Porzana. 
The Porzance inhabit Europe, Africa, India and A ustralia; the four 
species inhabiting the latter country are generally distributed, even 
within the tropics.

Order NATATORE8. 
Upon taking a general view of the birds of this order inhabiting 
Europe and Australia, our attention cannot fail to be arrested by 
some remarkable contrasts which present themselves to our notice.
