30. P. elegantissima, P. and J. Moderately common. 



Genus — Uvigerina, d'Orhigny.

FAMILY GLOBIGERINID^.

34. S. decor ata, Brady. In the paper on the " Muddy Creek 

 Foraminifera" (Trans. R. Soc, S. Aus., vol. XII., p. 11), I have 

 pointed out the slio-ht variation which this species, as well as the 

 next described, exhibits from the recent forms obtained from the 

 Challenger material. The Kent Town examples possess the same 

 varietar features as those obtained from Muddy Creek, but are in 

 much greater numbers than in the latter district. Moderately 

 common.

 figs. 11-13. Test rotaliform, much compressed laterally, consisting 

 of 2-3 convolutions, and about twelve chambers in all. Superior sur- 

 face nearly flat. Inferior surface slightly convex. Sutural lines de- 

 pressed, and on superior surface strongly curved. On the inferior 

 side the septation is marked by irregular depressed lines, enclosing
