ZOOLOGICAL GARDENS,

that stage of development at which other animals are 
born into the world ; but even then it does not leave 
the pouch for some time, as it may be seen with its head 
out grazing from it, and if, when more mature, it should 
leave the pouch, it immediately betakes itself to it when 
any danger threatens. The tendons of two of the belly 
muscles become converted into bone, but it is asserted by 
some observers that these bones have nothing to do with 
the support of the pouch. There are many other struc¬ 
tural features of this group which are well worthy of study. 
Generally three or four species are represented, and 
the Common Wallaby, Ualmaturus ualabatus , has bred 
in the Gardens. 
In one of the other houses of the Gardens where small 
cages are kept, there are frequently to be seen examples 
of the Dasyures, usually Dasyurus geoffroyi , which arc 
essentially carnivorous and are viverrine in appearance. 
Another familiar example of Marsupials is the Opossum, 
which differs from the rest of the group in occurring out 
of the Australian province, being found both in North and 
South America, whilst all the other Marsupials are res¬ 
tricted to the Australian region. 
The southern side of this house is set apart for the 
illustration of the Snides , or Hog Family. 
In one of the divisions of this side, the common Wild 
Pig of India is generally to be found, and alongside 
of it the Pigmy Hog of the Tcrai, also that remark¬ 
able porcine animal, the Babirusa of Celebes. These 
animals belong to the Artiodactyle section of the hoofed 
Mammalia, and to that division of it which is known as 
the Non-ruminantia in contradistinction to the other sec¬ 
tion the Ruminantia. The Artiodactyla are those hoofed
