Description

This shell is 4.5 mm high and 2.3 mm wide, and is composed of 4.5 whorls. The middle two whorls have prominent ridges, while the final, largest whorl is decorated with three strong ridges and three weaker ones underneath. The shell also features a straight, relatively long and wide siphonal canal that has its own set of ridges. The aperture of the shell is quite large and oval-shaped, transitioning smoothly into a slanted breathing tube.
