Observations. — In Dennant and Kitson's List we find the following 

 localities mentioned for this species: Muddy Creek (lower); Lower 

 Moorabool; and Murray River Cliffs, Oyster bed. These localities 

 indicate respectively, Oligocene (Balcombian), Miocene (Janjukian), 

 and Lower Pliocene (Kalimnan). The present record, from the 

 Beaumaris Cliffs, is new for the locality, and so links on. to that of 

 the oyster beds of the Murray River Cliffs, South Australia, in point 

 of age. This species, therefore, has a remarkably extended range. 

 The Beaumaris specimens are the umbonal parts of very heavy shells, 

 whilst the Balcombian examples are generally much thinner and 

 lighter. 



In the Dennant collection there is also a juvenile shell of the 

 same species from the Muddy Creek beds y( upper or Kalimnan). 



Additional Occurrence. — Beaumaris Cliffs, Port Phillip. Also upper 

 l)eds at Muddy Creek. Age. — Kalimnan (L. Pliocene).
