presence of Orders almost unknown except in Australia, are 
the most remarkable features of the Mammalian Fauna in 
Australia. The paucity of numbers is also a striking feature, 
the entire number of known species not exceeding 160 of all 
Orders. 
The BIMANA are represented by a variety or species of 
the genus iZomo, supposed to have micrated ‘from countries 
north of Australia at some remote period. The Australian 
Blacktfellow, as he is called, is believed to belong to the 
division of the human race known as the “ Oceanic “Negro, 
and though he does not present much resemblance to the 
Papuan, there can be little doubt but that both races emanate 
from the same source or centre. 
The Order QUADRUMANA is entirely absent fom 
Australia. The FERA! are also unrepresented, with the 
exception of the Native Dog (Canis dingo ), which in’ all 
probability is only coeval with man as an inhabitant of Aus- 
tralia. The PINNIPEDIA are represented by a few species 
of Seals, common to other parts of the Pacific as well as the 
Australian Coasts. 
The CETACEA are mostly of wide range, and can scarcely 
be said to belong to any country ; but the seas round Australia 
abound in whales of several species, and the shores swarm with 
porpoises. One genus, however, is peculiar to the warm seas of 
Northern Australia,—a species of Manatee ( Halicore Dugong ), 
an animal much valued for the medicinal qualities of the oil 
which it yields. 
The important Order UNGULATA is entirely absent from 
Australia. There is not even a Native Pig, though two 
species are found on the adjacent island of New Guinea. 
Since the advent of the white man all, or nearly all, of the 
most useful animals of this Order have been successfully 
acclimatized. The Orders PROBOSCIDEA, EDENTATA, 
and INSECTIVORA are also totally unrepresented. The 
CHIROPTERA number about 30 species;-of these five belong | 
to the PTEROPODID or Frugiverous Bats, eenerally 
called Flying Foxes, and they are all probably importations 
from New Guinea and the islands of the Dutch Archipelago. 
The Insectivorous Bats are chiefly of the genera HMarpyia, 
Mollossus, Taphozous, Rhinolophus, Nyctophilus, Scotophilus, 
Vesper tilio, and Nycticejus. 
The ovent Order of RODENTIA is limited in Australia to 
about 27 species of the Family 1 Murip&, and these are dis- 
tributed thus :—15 species are placed in the genus Mus, nine 
in the genus /Zapalotis, a genus only differing from Mus in 
the large ears and elongated tail, and three or “four species of 
the genus MHydromys, the Beaver Rats of Austraha and 
Tasmania,
