The Rufous-necked Wallaby (M. ruficollis ). 
The Short-tailed Wallaby ( M \ brachyurus). 
The Black-striped Wallaby ( Mdorsalis). 
The Brush-tailed Kangaroo ( Petrogale pencillata ). 
The kangaroos inhabit the continent of Australia, Tas¬ 
mania, New Guinea, and other of the adjacent islands ; they, 
in common with nearly the whole mammalian fauna of the 
Australian region, belong to the order Marsupialia. 
These animals derive their name (Greek, marsupion —a 
purse) from a pouch or bag situated on the lower part of the 
abdomen in the female, and containing the teats. The 
young animal being born—so to speak—prematurely, is in an 
undeveloped condition, and is at once placed by the mother 
the great kangaroo.
