Both tube and septum are semitransparent, colourless and glossy.The surface shows a microsculpture composed of shallow worm-like grooves interrupted by irregularly-set growth lines.At higher magnification, the microsculpture is composed of very small pits with a diameter of about 1 µm arranged in longitudinal rows. Septum vitreous, smooth, domeshaped, very protruding, with an indistinct mucro directed toward the right side. The septum shows some more or less parallel grooves arranged like waves coming from the tip of the mucro. Juveniles quite similar to the adults, and are distinguished by the more tapered shape, the smaller diameter and the less protruding septum. Larval stage and operculum unknown.</paragraph>
