THE BANDICOOTS. FAMILY PERAMELID. 
With the Wombats we take leave of the Diprotodont, or 
‘first primary subdivision of the Marsupials, and the Bandi- 
coots bring us to the first family of the second or Polyprotodon 
sub-division of the order, which includes the whole of its re- 
maining representatives. 
The Polyprotodonts derive their title from the presence of a 
numerous series of incisor teeth in the upper jaw; there being 
generally four or five nearly equal-sized pairs of these teeth in 
the upper, and three in the lower jaw, although in the case of 
one specialised genus the number is reduced to three pairs in 
both the upper and the lower jaw. In size the incisors are 
small, and the tusks are large and pointed ; while there is never 
that long gap between the incisorand molar series, which forms 
such a characteristic feature in the dentition of many of the
