CENSUS OF THE OLDER TERTIARY FAUNA OF AUSTRALIA. 241 



of great service in elaborating and in working out the relationships 

 of the Australian species. To Mr. Walter Howchin, F.Gf.S., I 

 am indebted for a census of the genera of Foraminifera, additional 

 to those already published chiefly determined from material 

 obtained from the Adelaide bore and Muddy Creek. It is very 

 generous of him to allow me to anticipate the announcement of 

 many interesting genera in our Tertiary deposits, previously 

 unknown as fossil ; I trust that the results of his labours in this 

 field of investigation will not long be witheld from us. 



The chief Areas and Localities of the Older Tertiary 

 Marine Deposits are : — 



South Australia. 



1. Bunda Plateau and cliffs of the Great Australian Bight, 

 extending to lat. 32° S. 



2. St. Vincent Gulf : — East coast of Middle Yorke Peninsula, 



Adelaide, Aldinga Bay, and Nepean Bay, Kangaroo Island. 



3. Gorge of the River Murray from Overland Corner to Lake 

 Alexandrina, and well sinkings on the Murray Plain adjacent 

 to the river. 



4. Mount Gam bier embracing Narracoorte, the Glenelg River 

 and Portland. 



Victoria. 



5. Muddy Creek, Hamilton. 



6. Cape Otway, Gellibrand River, and Jan Juc. 



7. Corio Bay and Waurn Ponds, Geelong. 



8. Bacchus Marsh ; Moorabool River. 



9. Balcombe Bay, Mordialloc, Cheltenham and Flemington, Port 



Philip. 



10. Gippsland Lakes. 



Tasmania. 



11. Table Cape, North-west Coast, the most Southern station in 



lat. 41° S. 



The area, over which patches of marine Older Tertiary extend, 

 is comprised within latitudes 41° and 32° and longitudes 148° and 

 128°, and probably so far as 123°. The marine beds of this age 

 appear for the most part to fringe the present coast line and except 

 the more northerly parts of the basin of the Lower Murray River 

 and the interior of the Bunda Plateau, no fossiliferous section is 

 beyond 50 miles from the sea shore ; and judging by their 

 distribution, thickness and altitudes of sites they appear not to 

 have extended much beyond their present limits. 



The greater mass of the formation does not attain to a greater 

 elevation than 200 feet above sea level ; but in the Adelaide bore 

 was proved for a depth of 250 feet below sea level, and on the 

 Bunda Plateau to about 500 feet. For the most part the secular 

 elevation of the Older Tertiary sea-bed has been of small amount
