 Localities. — ^Muddy Creek ; Moorabool Valley ; Gellibrand 

 River ; Mornington ; Bairnsdale ; Point Campbell ; Lake Conne- 

 warre ; Newport ; Altona Bay ; Royal Park (lower beds) ; Beau- 

 maris (Eocene limestone pebbles). All the above occurrences 

 being of Eocene age. 



Observations. — In his original description T. Woods gives 

 fairly full particulars of the young of this species. He was 

 also perfectly aware that he was describing only a young shell, 

 but he regarded his specimen as " sufficiently developed to 

 determine its character." Owing to this his description appears 

 to be somewhat fuller and more careful in detail than usual.
