12. Rhizammina alg^formis, Brady, C.R., pl.xxviii. f.1-11. 



Family TEXTULARID^. 

 Subfamily TEXTULARIN^. 



13. Tritaxia TRICARINATA, Reuss; Chapman, '"rheForaminifera,"

 pl.viii. f.60.

16. Operculixa complanata, var., Leymerie and Defrance. 



This list shows that very many forms still living, some of which, 

 marked *, occurring in Port Jackson to-day, already existed" in 

 profusion in Eocene time in more southerly latitudes. Only dust 

 from the specimen, which is kept in the Geological Laboratory 

 at the University, was examined, and the Foraminifera in it were 

 perfect. It is unfortunate that the locality label has been lost. 



9. In connection with some work done on the Polyzoa in the 

 Pokolbin Permo-Carboniferous liuiestone. I sectioned a number 

 of rocks, which proved to be rich in Foraminifera. The follow- 

 ing genera were represented in the thin slides : — 



1. Nuhecularia (very abundant). 



2. Nodosaria (very abundant). 



3. Vaginidina (?) 



4. Haplophragmium (rare). 



5. Eotalia{1). 



6. Sphceroidina or Globigerina (I). 



7. Cornuspira {involvens, Reuss ?). 



The genera Nuhecularia, Nodosaria and Cornuspira have 

 already been identified in Australian Permo-Carboniferous rocks 

 by Mr. W. Howchin, F.G.S. ^Ir. Howchin describes them in
