Genus ZEMIRA, H. and A. Adams. 

 [Gen. Eec. Moll. vol. i. 1853, p. 110.] 



Related to Ehurna, from which genus it may be distinguished 

 by having a much smaller umbilicus, and by the possession of 

 a prominent denticle towards the anterior of the outer margin. 

 This projection is the continuation of the spiral channel on the 

 forepart of the shell. 



Type. — Pseudoliva australis, Sowerby. 



Zemira prsecursoria, Tate.

The only example of this species in the Museum collection is 

 not well preserved. Z. prcecursoria, according to Professor Tate, 

 ditfers from Z. australis, Sby., which inhabits the temperate seas 

 of Eastern Australia, by possessing a longer spire and narrower 

 body-whorl, narrower sutural sulcus, and in having more pro- 

 nounced spiral ridges. 



Dimensions. — Length 14 mm.; breadth 9 mm.; length of 

 aperture 9 mm. 



Form, and Loe. — Eocene : Muddy Creek, Victoria.
