CENSUS OF FORAMINIFERA. 



Table !'.— conlimied. 



365 



The marine beds of Secondary age have an immense develop - 

 ment throughout the central regions of Australia. The lithological 

 features of this formation are very uniform both in section and in 

 area, and so far as these researches have gone the distribution of 

 the foraminifera in the Australian Cretaceous sea was equally 

 general and uniform. The most remarkable feature in the Table 

 is the unusual proportion of foraminifera with arenaceous tests, 

 there being no less than twenty species belonging to this class out 

 of a total of fifty-six. 



UPPER PALEOZOIC. 



Permo- Carboniferous. 



Australian foraminiferal material of Palaeozoic age, so far as 

 obtained, is of the most scanty description. Only two localities 

 have hitherto yielded examples of these minute forms, and under 

 cii-cumstances not the most favorable for their elucidation. The 

 results, so far as can be determined at present, are contained in the 

 subjoined Table.

 determined with some reservation from two transparent rock sections
