Description

Reverse view of holotype

In the original description, Powell described the species as follows:

Shell small, ovate-fusiform, aperture less than half shell height. Whorls 6½, including smooth, blunt-tipped, rather narrow protoconch of 2 whorls. Axial sculpture of broad, heavy folds, extending from suture to suture, but not over the base, 8 on the penultimate. Spiral sculpture of regular linear-spaced cords, 14 on the penultimate and about 38 on body-whorl and base. Shoulder flattened, not prominent. No subsutural fold. ^[2]

The holotype of the species measures 9 mm (0.35 in) in height and 3.9 mm (0.15 in) in diameter. ^[2]

Taxonomy

The species was first described by A.W.B. Powell in 1944. ^[2] The holotype was collected from Torquay, Victoria, at an unknown date prior to 1944, and is held by the Auckland War Memorial Museum. ^{[3] [4]}
