 much more characteristic of the Upper Bed (Miocene) than the 

 Lower (Eocene).- — ^W. H. 



I have already stated that the fauna has a strong modern 

 facies, but at the same time it does not materially differ in its

 many points of contrast with the Eocene. The only genera of 

 special interest are Lacuna and Cyamium^ both now known for 

 the first time as constituents of a Tertiary fauna in Australia, 

 and as yet unknown in its recent one. The former belongs to-
