The shell is of moderate size (maximum length 19 mm) and broadly fusiform. The spire is high, consisting of one and one-half convex nuclear whorls and four convex postnuclear whorls. The suture is well-impressed. The body whorl is moderately large and ventricosely fusoid. The aperture is large and ovate-lenticular, and formed into an erect peristome, its outer margin crenulate, the columellar lip smooth and adherent, except at its anterior end. In the shoulder region, midway between each two consecutive varices, a short, open, dorsally facing anal siphonal tube is formed. The siphonal canal is short, broad, narrowly open, and distally recurved.
The body whorl bears three varices, represented by barely discernible former outer apertural margins posteriorly and thin, bladelike varical flanges anteriorly. Each varix is comparatively simple and is composed of a thin, flattened vane, showing the outer shell sculpture on both its inner and outer surfaces, in the form of closely spaced corrugations. Major axial sculpture is otherwise lacking. Spiral sculpture consists of numerous fine cords or threads of equal strength on most of the body of the shell, changing to alternating major and minor cords near the base of the body, and back to cords of equal strength on the canal. Very fine axial growth lamellae are crossed by the cords, and where these two types of sculptural elements intersect, low, laterally expanded scales are formed. Shell color is white or yellow-white. There are indications that a thin intritacalx layer covers the entire shell, imparting to it a flat-white color.
