1. PHASCOLOMYS. 217 



This spocies, the oldest known of the group, presents a remark- 

 able exception to the usual rule of size in Tasmanian animals, these 

 being generally larger instead of smaller than their continental 

 allies. The species seems to be well distinguished from Ph. mitchelli 

 by this one character of size, but otherwise there appears to be no 

 difference of importance between the two.
