INTRODUCTION. 
531. Parra gallinacea,, Temm. Vol. VI. PI. 75. 
Inhabits the northern parts of Austraha and New Guinea. 
Genus Rallus, Linn. 
We have here again a genus of birds the range of the species of which is most extensive, for there is no 
country in whicli one or other of them is not to be found. 
532. Rallus pectoralis, Cm. . , Vol. VI. PI. 76. 
533. Rallus Lewinii, Sioains , Vol. VI. PI. 77. 
Genus Eulabeornis, Gould. 
Generic characters. 
Bill longer than the head, nearly straight, but slightly curved do-v\Tiwards ; 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 Rallus ; toes not so much lengthened as in that genus ; tail long 
cuneiform ; the ivehs 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. PI. 78. 
Genus Porzana, Vieill. 
The PorzancB inhabit Europe, Africa, India and Australia ; the four species inhabiting the latter country are 
generally distributed, even within the tropics.

536. Porzana palustris, Gom/c/ Vol. VI. PI. 80. 
537. Poi-zana leucophrys, Gould . Vol. VI. PI. 81. 
538. Porzana immaculata ............. Vol. VI. PI. 82. 
Order NATATORES, ///. 
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. I allude to the great 
excess in the number of species of some of the principal groups, and the paucity of others ; for instance, of the true 
AnatidcB or Ducks, exclusive of the Mergansers, the European fauna comprises at least forty species, while eighteen 
are all that are known in Australia ; of the Laridce or Gulls, exclusive of the Terns, twenty species inhabit Europe, 
while three are all that are known in Australia ; on the other hand, sixteen species of Terns frequent the shores of 
Australia, while only twelve resort to those of Europe ; of the family Procellaridce or Petrels, nearly forty species 
enliven the Australian seas, while . seven are all that are known to inhabit the seas of Europe ; no Puffins or 
Guillemots are found in the seas south of the Equator ; while the Penguins are unknown north of the line ; and 
the Grebes and Cormorants are equally numerous in both hemispheres. 
Family ANATIDvE, Leach. 
Genus Cereopsis, Lath. 
But one species of this singular and strictly Australian form has yet been discovered.
