HE island of Tasmania is connected, as it were, with the conti- 
nent of Australia by two chains of islands, the lines of which 
are afterwards continued in the mountain-systems both of Tasmania 
and Australia. ‘The Tasmanian systems pass from north to south in 
a strangely zigzag course, throughout which the mineralogical cha- 
enabled to take its measurements before it was partially destroyed in removing the 
matrix. The extreme length of the crown was 84 inches; the length of surface 
in wear, 6.4, inches; number of plaits, 10, and a talon ridge ; number of disks of 
wear, 8.
