Fossil Fish Remains, 293 



From the state of preservation of the specimens in our beds, 

 we have no hesitation in stating that we think the majority of 

 the occurrences in the Kalimnan beds are due to their having 

 been derived from the older Barwonian beds. This we think is 

 somewhat analagous to the fact of so many Pliocene specimens 

 being of a derived character in the Northern Hemisphere, and, 

 where no indication of the state of preservation is given, the 

 results of an inquiry into the distribution of species may be 

 somewhat misleading. 



The local terms, Kalimnan, Balcombian, Jan Jukian, and 

 Barwonian, have been used by us owing to the very considerable 

 confusion and diiference of opinion surrounding the use of the 

 ordinary terms such as Miocene, Oligocene, Eocene, and to the 

 fact that as yet there is no absolute certainty on the strati- 

 graphical succession of our beds. 



As far as the evidence points up to the present, the older 

 series has been termed Barwonian ' with its two sub-divi- 

 sions, Balcombian and Jan Jukian, of which the latter has been 

 indicated as the older.- To this series various ages have been 

 assigned, such as Eocene, Oligocene, and Miocene, for different 

 portions of the same series. 



Then for the series distinctly unconformable to the Barwonian 

 and distinctly separable by its molluscan fauna the name of 

 Kalimnan has been given ^; and this series has been variously 

 referred to as Oligocene, Miocene, and Pliocene.
