On the Absence of Nummulites in the Tertiary of Southern 
Australia. 
One of the chief factors which gave support to the conclusion 
that the Australian Tertiary beds belong in part to the Eocene or 
Niunmulitic formation, was the erroneous record of the genus 
Nummulites from the lower beds at Muddy Creek, near Hamilton, 
Victoria. The nummulinoid foraminifer occurring so commonly 
throughout the main portion of our Tertiaries was, however, correctly 
assigned to the genus Amphistegina as early as 1865 by Tenison 
Woods*, for whom, as before stated, it was named by Prof. Rupert 
Jones. In describing the foraminifera from Muddy Creek, Woods 
writes as follows : — “ The foraminifera are large and numerous ; 
indeed one species, Amphistegina vulgaris, d’Orb., is so common 
that the clay is principally composed of it. Its large lenticular 
form can be traced in almost every pinch of the debris, and what 
makes the individuals more conspicuous is that they have all 
received the ferruginous glaze which makes them look like little 
coins. From their numbers the strata may in truth be called an 
Amphistegina- bed, similar to that in Vienna, and possibly of the same 
age. Other Foraminifera occur, such as Discorbina turbo, Pulvinulina 
pulchella, Planorbulina Haidingeri, Operculina complanata, Poly- 
morphic lactea, Textularia sagitlula, Miliolina semiluna, and M. 
trigonula. Next in frequency to the Amphistegina vulgaris is the 
Operculina complanata, Bast., and though equal in size to the 
species found at Mount Gambier, it is much more common in the 
latter locality.” 
The earliest reference to the supposed occurrence of Nummulites 
in Australia appears to be that given by T. R. Jones in 1882, f
