Belmont, near Geelong (J. F. Mulder). — Barwonian. 



Grange Burn. Upper Beds (Nat. Mus. Coll., purchased from 

 R. Lindsay; also presented by G. Robinson; also Spry Coll., 

 and Pritchard Coll.) ; Beaumaris, Port Phillip (Dixon Coll ; 

 Pritchard Coll. ; Nat. Mus. Coll., purchased from J. F. Bailey). 

 — Kalimnan — all more or less worn, and therefore probably de- 

 rived from Balcombian. 



Observations. — This species was first recorded by the late Sir 

 F. McCoy from " the Miocene of Victoria " in 1866 (15, p. 16). 

 Authentic specimens of 0. contortidens from the Lower Ter- 

 tiary beds of Europe have assisted us towards this identification. 

 The variations exhibited in the above series seem to be easily 

 accounted for by the different positions which they occupied in 

 the jaw. The species occurs in Europe and North America in 

 strata of Eocene to Pliocene ages.

Obsei'vations. — This species may be distinguished from the 

 foregoing 0. contortidens, Ag., by its more robust crown, convex 

 outer face, depressed and smooth inner sm-face, the former 

 being of a more slender type with a convex and striated inner 

 surface. This species was originally described from the 

 Waipara and Oamaru formations. New Zealand, Upper Cre- 

 taceous and Oligocene respectively.
