Valuta anti-cingulata and V. anti-scalaris (McCoy), which so 

 singularly represent the species of English Volutilites indicated by 

 the names I have vised for them, it has the hlunt mammillated spire of 

 Valuta instead of the sharp-pointed regular apex of Volutilites found 

 in them. It likewise differs in completely wanting the spiral striae 

 at the base, and differs from all the allied forms in the character 

 indicated by the specific name, the reversal of the position of the 

 larger and smaller teeth or plaits on the pillar hp, the posterior 

 of which is always the largest instead of the anterior, as in most 

 Volutes. 



Abundant in the blue Oligocene Tertiary clays of Fyansford 

 (A*" 28) ; also in those of Muddy Creek, near Grange River ; also 

 in those of Moolap (A* 14) ; occasionally found usually of smaller 

 size in the similar clays and limestone between Mount Eliza and 

 Mount Martha.
