The more depressed varieties have a sharp peripheral keel. 



P. schreibersii was recorded by Howchin from the Balcombian 



of Muddy Creek. 



Frequent in the foraminiferal rock of the Filter Quarries.

It interesting to note the occurrence of this species as a fossil 

 in the Balcombian series in Victoria. At Muddy Creek Mr. 

 Howchin found it to be moderately common ; and it has also 

 occurred in the Janjukian at several localities examined by the 

 writer ; whilst in the Kalimnan it is an exceptionally abundant 

 form. The species seems to be restricted to a very limited 

 area at the present day, for Brady records it only from foar 

 localities between Bass Strait (at Moncoeur Id.) and Cook 

 Strait, New Zealand ; and from two stations on the West Coast 

 of Patagonia. These localities are practically co-extensive 

 with the Middle Tertiary shore-line, which had so many species 

 of mollusca in common, embracing the Santa Cruz series of 

 Patagonia, the Oamaru series of New Zealand, and the Bar- 

 wonian of Victoria. The tests of E. clathrata from the Jan- 

 jukian are more heavily built than those from the Kalimnan 

 and Recent deposits. 



Very common in the Batesford Limestone at both Quarries.
