SUB-FOSSIL REMAINS FROM KING ISLAND. 
The greatest basal length of any of our specimens of D. macu- 
latus is 98 mm., and that particular specimen came from 
Queensland ; a second, measuring 97 mm., from Tasmania ; 
a third, measuring 96 mm., from Victoria; are particu- 
larly large ones. In the British Museum catalogue the 
basal length of one is given as 101, but this, as well as 
the above three, may be regarded as decidedly above the 
average size. Even if we take 100 mm. as the basal length 
of D. maculatus, the above table still shows very clearly the 
great relative size of the King Island species. 
In the following tables the same species are grouped in accord- 
ance with their tooth measurements :—
