Secondary formations, are marsupials ; and from the 
absence of higher mammals, or their remains, from 
Australia, it is evident that this distrift was separated 
at this early period from the mainland, ere the higher 
forms had been developed and widely distributed. Isolated 
in Australia, in the struggle for existence, the marsu- 
pials have undergone wonderful modifications and have 
taken on the habits and the externa! forms of wolves, 
bears, rabbits, rats, squirrels, bats etc., and they are 
known to the colonists by these names. Some of the 
recently extinft marsupials were giants of their kind. 
The specimen of the brown bear (Ursus) exhibited, that 
so closely resembles the Australian %t koala" or native 
t( Bear," is quite a baby and gives no idea of the size of 
the adult animal. On the sides of the building, by these 
specimens, are suspended two badly stuffed skins of the 
manatee or " water-cow " of the colony — an animal that 
will be referred to later. 
In the next case, is shewn a colle6lion of skulls

skulls — of native Indians, of an European boy, of a negro, 
of a Chinaman and of a coolie. The throat pouch or vocal 
drum of the howling monkey, male and female specimens, 
are also shewn ; the male pouch is large and the female 
pouch, taken from a full grown specimen, is extremely 
small, so that the males are responsible for the terrific 
din which causes the stranger to stand aghast. Among 
the skulls are- shewn those of various monkeys, of the 
ant-eater, the armadillo, the yawarre or opossum, the 
manatee, the jaguar, various deer, the labba, the 
waterhaas, and lastly, of the tapir — that curious hoofed 
animal or ungulate, charafterised by the possession of a
