Observations. — Specimen's in our collection show the same 

 range of variation as has already been indicated by the forms 

 figured as Carcharodon auriculatus, angustidens, heterodon, 

 toliapicus, etc. 



This species appears essentially to belong to the Barwonian 

 series, as our knowledge of its existence in the Kalimnan is 

 restricted to one worn specimen. 



Middle and Upper Eocene of Europe and North America,

 also recorded from the Oamaru formation (Oligocene) of New
