This species of Odontaspis is perhaps the rarest of the genus in 

 Victoria. It did not occur in the series of Australian Tertiary 

 fish-teeth examined by Dr. G. B. Pritchard and myself in 1904, but 

 was recorded by McCoy in 1867 under the name of Lamna elegans 

 from Victorian Miocene beds, and was also noted by R. M. John- 

 ston from Tasmania in his " Notes on the Tertiary Beds of Table 

 Cape." 



It is readily distinguished from the other Australian species 

 of Odontaspis by its stouter build and strong divergent roots. There 

 is little doubt that this Avorld-wide species is also represented in 

 New Zealand by Davis' Lamna huttoni, the type of which has a 

 rather long crown, gently but sinuously reflexed. The Victorian 

 specimens are destitute of lateral denticles, owing to attrition or 

 partial decay of the base. 



Occurrence. — Tertiary (Janjukian). Waurn Ponds, near Gee- 

 long. Fyansford Hill, near Geelong. Presented by Miss Lenna 

 Bryan.

Observations. — The fossil fish-tooth figured by J. W. Davis as 

 ccited above has long l^een a puzzle as to its real relationship. That
