are the Manatees and Dugongs; (ili.) Ceracra, the Baleen and 
Sperm Whales, Narwhal, Dolphins, &c.; (iv.) Insectivora, the

Cattle, Sheep, Horse, &c., by far the most import .nt Order ; (viii.) 
Carnivora, the Lion, Wolf, Weasel, Walrus, Seal, &c.;  (ix.) 
QuapruMmANA, the Monkeys, Apes, Lemurs, &c.; and (x.) 
Primates, Man. 
Of these ten Orders only five, the second, third, fifth, sixth, 
and eighth have to be dealt with here as Australian, four of the 
others not having as yet been recorded from this Subregion, while 
Man is relegated to a different—the anthropological—branch of 
the science. 
The range of this Subclass is, as may be supposed, cosmopolitan 
no region having been visited by man, whether the ice-bound 
wastes of the arctic seas, or the burning sands and miasmatic 
swamp-forests of the tropics, in which widely different forms of 
mammalian life, from the Rein-Deer and Musk-Ox. the White 
Bear and the Walrus of the inhospitable polar shores on which so 
many of the bravest and best of the intrepid heroes of our Anglo- 
Saxon race have left their sad and but surmisable record of im- 
perishable fame, to the Aye-Aye and the Armadillo, the Tapir 
and the Gorilla of lands which teem with so exuberant a life as 
to be actually more deadly to man than the barren, the shud- 
dering silences of the long winter night of the polar seas. 
In point of numbers and importance the Eutherian Mammals 
greatly exceed the two preceding divisions of the class, except in 
Australia, this wondrous relic of an older era in our planet’s 
history, the latest and the most marvelous of our discoveries. 
Leaving the marine mammals—which are naturally cosmopolitan 
—for the present out of the question, the truth of this assertion 
may be seen ata glance by the fact that in Australia and its 
attendant islands only about seventy species of terrestrial Eu- 
therian Mammals,—one of which, the Dingo, is more than doubt- 
fully indigenous—have been differentiated with any degree of 
certainty, and, with the exception of the Australian Water-Rats 
(Hydromys) and the more closely allied genera, none are of any 
special interest, while not a single species is of any commercial 
value whatever. Asan illustration of the poverty of the Australian 
fauna in this respect it is only necessary to call the attention of 
my readers to the obvious fact that all domesticated mammals, 
one at least of which has placed Australia in the proud position 
which she now holds, have their origin in far distant lands. As 
a set-off to this, from a naturalist’s point of view, unsatisfactory 
state of affairs we can of course point with pride to the great
