Popis

The shell is of moderate size (maximum length 21 mm) and broadly fusiform. The spire is high, consisting of one and one-half nuclear whorls and six moderately convex postnuclear whorls. The suture is distinct but not impressed. The body whorl is moderately large and broadly fusoid. The aperture is ovate to subcircular, with a barely perceptible anal sulcus. The outer apertural lip is minutely crenulatc, the crenulations reflecting the spiral shell sculpture; the inner surface of the outer lip is weakly, briefly lirate. The columellar lip is adherent above, detached and erect below, and smooth over the columella. The siphonal canal is moderately short and broad, narrowly open to the right, and briefly recurved at its tip.
The body whorl bears six prominent, widely spaced varices. Spiral sculpture consists of five major cords, these occurring from the shoulder margin to the base of the body; two or three ephemeral minor cords may be present on the shoulder, and another one may occur between the third and fourth major cords from the shoulder margin. A gap in the spiral sculpture is followed on the canal by one or two major cords. The cords are evident between the varices and are strongly elevated on the trailing edge of each varix. The leading edge of each varix is strongly fimbriate.
Shell color is fleshy pinkish-orange, darkest on the varices; the intervarical areas are paler, owing to the presence of a thin, white intritacalx. The aperture is orange-pink.
