Fossil Fisli Remains. 271 



Specimen (d) — Length, 26 mm.; breadth, 10 mm. ; heiglit, 7 mm. 



Locality and Horizon. — From the nodule band at the base 

 of the cliffs, Beaumaris, Port Phillip. National Museum Col- 

 lection, collected by the late Mr. W. Kershaw, and the late Mr. 

 W. B. Jennings ; also in the private collections of Messrs. Dixon 

 and G. B. Pr it chard. 



From the nodule band at the base of the upper beds Grange 

 Burn, near Hamilton, Western. Victoria. Nat. Mus. Coll., pre- 

 sented by Messrs. F. Spry and A. A. Kelley, also Coll. G. B. 

 Pritchard. 



The majority of the specimens hitherto obtained of this species 

 have been from the Kalimnan Beds, but as many show consider- 

 able erosion it is probable that they may have been derived from 

 the Balcombian. Cixrlewis; Beds, near Geelong (Nat. Mus. Col- 

 lection, presented by A. C. Curlewis); Murgheboluc (T. S. Hall 

 Coll.) — Balcombian. 



AVarranooke, 23 miles north of Stawell (Nat. Mus. Collection 

 from Mines Department, 3502). — Banvonian. 



Observations. — The genus itself has been previously recorded 

 from our Tertiaries by Tate (25, p. 246), and by Hall and 

 Pritchard (12, p. 304), but no described Australasian Tertiary 

 species has hitherto been known. For confirmatory evidence of 

 the generic affinities of our specimens thin slices of the teeth 

 have been microscopically examined, and they show the irregu- 

 lar habit of the pulp-canals and the characteristic outspread 

 canaliouli near the upper surface, a feature which we have also 

 seen in actual recent specimens, and which has also been well 

 illustrated by Owen in his Odontography (22). 



The first EurojDean Tertiary record of Cestracion was made 

 by Winkler (27, p. 17) from the Bruxellian (Middle Eocene) of 

 Belgium, and subsequently by A. S. Woodward (32, pp. 6, 7, 13) 

 from the London Clay (Lower Eocene),
