CONTRIBUTIONS TO A KNOWLEDGE OF AUSTRA- 

 LIAN FORAMINIFERA. Part I. 



By H. L Jensen, B Sc. 



(Plate xxiii.) 



The present paper is in the main a compilation of species which 

 I have identified in sands and other materials obtained from 

 various quarters. It is the result of over four years' intermittent 

 work on, and study of, our foraminiferal fauna. Very few new 

 species have been discovered, thanks to the very thorough work 

 of previous workers, especially Brady, who described and figured 

 those dredged on the voyage of the 'Challenger.' Many varieties 

 differing in minor details from those alread}^ known and figured 

 were found in the present research, but as the custom of creating 

 new species on trivial differences is objectionable, I have assigned 

 them to the species to which they exhibited most affinity, making 

 a special note where the difference was somewhat marked. The 

 work has been done in the Biological and Geological Departments 

 of the Sydney University, to which I wish to express my grati- 

 tude for courtesy shown. 



Sands from Wollongong, Byron Bay, Sydney Heads, Lizard 

 Island, the Palm Islands, New Guinea, and Lord Howe Island, 

 as well as dust from a specimen of Turritella limestone and 

 sections of Pokolbin limestone have been examined for Foramini- 

 fera.
