1. Voluta Hannafordi, McCoy. 



Reference. — Prodromus Pal. Victoria, Decade I., tab. vi., fig. 1, 

 1874; Decade IV., tab. 37, fig. 1. 



Localities. — Older beds at Muddy Creek ! ; clays at Schnapper 

 Point ! ; Port Fairy, Warrnambool ; and at Fyan's Ford {McCoy). 



This species is remarkable for its large pullus and winged 

 •outer-lip ; the whorls are obtusely angled and nodosely-tubercu- 

 late ; the posterior slope of the body whorl is spirally ridged or 

 lined, the front is smooth. 



Length, exceeding 150; breadth, 90; pullus, 12 in diameter. 



The only other winged species are F. macroptera, McCoy, and 

 F. Mortoni, Tate, which are smooth, or nearly so, with a small 

 pullus. 



2. Voluta heptagonalis, spec. nov. Plate iv., figs, i and 7. 



Shell narrowly fusiform, with a moderately long scalar spire 

 •ending in a large spherical pullus of one and a half smooth whorls, 

 the apex of which is laterally immersed ; the pullus is partitioned 

 off* from the spire. Whorls, four, beside the pullus ; the first one 

 convex, spirally lined, and faintly plicate, at first very narrow, 

 but enlarging and developing a shoulder and strong costse on the 

 next whorl ; the two other spire-whorls angulated in the posterior- 

 third, the area next to the suture being nearly flat or slightly
