THE POUCHED MICE. 167 
Shrews (Zaza), and in South America by the smaller kinds 
of Opossum. ‘The largest of the thirteen known species does 
not exceed a Common Rat in size, while the majority are con- 
siderably smaller than that animal. Whereas in all the 
Australian species the fur of the back is not striped, the 
majority of the Papuan representatives of the genus have 
striped backs, although a few agree in this respect with their 
Australian congeners.
