6. — The Batesford beds, in common with other Janjukian 

 strata, occupy a middle position in our Tertiary series, and are 

 younger than the richly fossiliferous Balcombian clays and 

 sands of Mornington and Muddy Creek (Lower Beds). 



In conclusion, I desire to express my sincere thanks to Dr. 

 T. S. Hall, M.A., for many specimens and samples of foramin- 

 i feral material with which I began the examination of the 

 microzoa of these quarries. I am also indebted to Mr. G. W. 

 Cortous, of Geelong, for kindly supplying me with further 

 fossiliferous material ; as well as Mr. W. B. McCann, as before 

 mentioned. 



The types of the new species and representative specimens 

 have been presented to the National Museum collection.
