Polystoinella suhnodosa, Miinster sp. 



Rohidina suhnodosa, Miinster, 1838 (fide Roemer), Neues Jahrb, 

 fiir, Min., etc., p. 391, pi. III., Fig. 61. Polystomella 

 suhnodosa, Miinster sp., Bradv, 1884, Rep. Chall. vol. 

 IX., p. 73-1, pi. ex., Figs. \a, b. 



Howchin has noted this species from Muddy Creek, but only 

 from the Upper Beds. One specimen from the Filter Quarries. 



Pohjstoniella antonina, d'Orbigny. PI. II., Figs oa, b. 



P. antonina, d'Orbigny, 1846, Foram. Foss. Vienne, p. 128, pi. 

 VI., Fig. 17, 18. 



This species somewhat resembles P. suhnodosa, Miinst. sp., but 

 differs in its much greater umbilical diameter, in the fewer 

 exposed chambers, and in its coarse septal bars. It has been 

 previously recorded only from the Miocene of the Vienna Basin. 



Three examples from the Filter Quarries. 



Polystomella crispa, Linne sp. 



P. crispa, Linne sp., Brady, 1884, Rep. Chall. vol. IX.. p. 736, 

 pi. ex., Figs. 6, 7. 



Recorded only from the later Tertiary beds by Howchin, viz., 

 from N.W. Bend, Adelaide, and Muddy Creek (Kalimnan). 



A few examples met with in the limestone of the Filter 

 'Quarries. 



Polystomella rerriculata, Brady. 



P. verriculata, Brady, 1884, Rep. (liall., vol. IX., p. 738, pi. 

 ex., Figs. 12a, b. 



As a living form this species is practically restricted to its 

 early Tertiary geographical position, it having been found off 

 E. Moncoeur Id., Bass Strait, and in Curtis Strait, Queensland, 

 bv the ''Challenger." 



Howchin records this species as rare at Muddy Creek (Bal- 

 combian). 



A few examples found in the Filter Quarries.
