I have no additional information respecting this noble species ; all the examples of which, that have come 
under my notice, have been obtained in the brushes of the east coast of Australia. 
Genus Circus, Lacep, 
Two if not three kinds of Harriers inhabit Australia, consequently the number of species is nearly equal in 
Europe, Asia, Africa, America, and Australia ; those inhabiting the latter counti-y are precisely of the same form, 
and perform the same offices as their near allies do in the other parts of the world.

Family STRIGIDyE, LeacL 
Genus Strix, Limi. 
While as a general rule other countries are only inhabited by a single species of the restricted genus Strix, 
the Fauna of Australia comprises no less than four, all of which appear to be necessary in order to prevent an 
inordinate increase of the smaller quadrupeds which there abound.

Genus Athene, Bote. 
A genus of diurnal Owls, of which five species are natives of Australia ; the smaller kinds are represented 
in Europe and Asia by the Athene noctua, A. Cuculoides and A. Brama ; the larger kinds have no representatives in 
the northern hemisphere.

Athene marmorata, Gould in Proc. of Zool. Soc, Part XIV. p. 18. 
All the upper surface, wings and tail dark brown, obscurely spotted with white round the back of the neck, 
on the wing-coverts and scapularies ; inner webs of the primaries at their base, and the inner webs of the lateral 
tail-feathers crossed by bands, which are buff next the shaft and white towards the extremity of the webs ; face 
and chin whitish ; under surface dark brown, blotched with white and sandy brown ; legs and thighs fawn-colour ; 
bill horn-colour ; feet yellow. 
Inhabits South Australia, is much larger than A. maculata, but so nearly allied to, and so much like that 
species, that I have not thought it necessary to give a separate figure of it.
