 beautifully canccllate, with a few elevated, shining, spiral and 

 transverse lira? ; outer lip simple, columelUi arcuate. 



Bass Straits, rather common, but so minute that the shell 

 easily escapes notice. I may be wrong in assigning the species 

 to the genus Dankeria. The lattice pattern is so large, and the 

 transverse and spiral ribs, which form it, are so far equal, that 

 it makes a unique form.
