Cirsonella translucida May, 1915 Acremodontina translucida is a species of sea snail, a marine gastropod mollusk in the family Trochaclididae, the ataphrids.
(Original description) The small, white shell is translucid and smooth, except for growth lines, elevated.
The only whorl of the protoconch is very minute, the others are rapidly increasing.
The columellar lip expands over a deep, narrow umbilicus, sometimes covering it, below which it suddenly contracts, and the expansion is very slight.
[2] This marine species is endemic to Australia and occurs off Tasmania in the subtidal zone and offshore.
