Syntomodrillia circinata is an extinct species of sea snail, a marine gastropod mollusc in the family Drilliidae.[1] Fossils of the species have been found in strata of the Port Phillip Basin of Victoria, and date to either the late Oligocene or the early Miocene.
In the original description, Powell described the species as follows:
Species very similar to obsoleta, but much larger, axials more erect, and connected across the shoulder-angle by a weak thread; five moderately strong spirals on the neck. Axials 11 per whorl.[2]
The holotype of the species measures 6 mm (0.24 in) in height and 2.5 mm (0.098 in) in diameter.[2]
