Observatio?is. — The median palatal teeth referred to under the 

 above name all differ in being more depressed, and having more 

 closely set denticles than those of the living Myliohatis australis, 

 Macleay. 



M. moorahhinensis has been previously found in the Kalimnan of 

 Beaumaris; and in the boi-ings in the Mallee ranging from Jan- 

 jukian to Kalimnan. 



The tooth from Torquay is even more slender and depressed than 

 the Beaumaris specimens, but evidently belongs to the same species. 

 This is the earliest appearance of the genus in our Tertiary beds. 



Occurrence. — One example from the Tertiary (Janjukian). Bird 

 Rock Cliffs, Torquay, near Geelong. Pres. by Mr. W. J. Parr. 



Fam. Sparidae. 



Genus SaPgUS, Cuvier. 



Sargus laticonus, Davis. (Plate IX., Fig. 9.) 



Sargus laticonus, Davis, 1888, Trans. R. Dubl. Soc. Ser. 2. vol. 

 IV., p. 4.3, pi. VII., figs. 3-8. 



Observations. — This genus and species has not been recorded pre- 

 viously from the Australian Tertiary strata, although it is a well- 

 known fossil in the New Zealand Oamaru system. It is there found 

 with some frequency in the limestone beds of Coleridge Gully. 

 Broken River, Castle Hill, Trelissic and Canterbury. It is espe- 

 cially interesting to find this fossil in our Batesford fauna, since the 

 writer has more than once referred this series to a similar period as 

 the Oamaruian. 



The specimen here figured is one of the anterior cutting teeth, 

 and is exceptionally broad, but not unlike Davis's figure 7 on pi. 

 VII. of his paper. 



Occurrence. — Tertiary (Janjukian). Limestone quarries, Bates- 

 ford, near Geelong. Pres. by ISIr. D. Culliney.
