The suggestion that the Balcombian to Kahmnan Tertiary 

 beds of Southern Austraha comprise one period, the Miocene,, 

 seems to be untenable from the fact that the succession above 

 the Kalimnan passes upward in sequence, and a new arrange-

 of a new horizon between the Kalimnan and the Werrikooian 

 to include a Lower Pliocene horizon, which speaking faunisti- 

 cally, is not possible.
