Description

The shell is of moderate size (maximum length 27 mm) and fusiform. The spire is high, consisting of one and one-half convex nuclear whorls and six shouldered postnuclear whorls. The suture is impressed and undulate. The body whorl is of moderate size and fusoid. The aperture is of moderate size and ovate, with a narrow, shallow anal sulcus. The outer apertural lip is thin, thickening rather quickly away from the growing edge; the inner surface of the outer lip bears seven weak, transversely elongate denticles, these becoming moderately weak brae more deeply within the aperture. The columellar lip is weakly arcuate, smooth to pustulate anteriorly, and entirely adherent. The siphonal canal is moderately long, straight, open, and weakly recurved distally.
The body whorl bears seven or eight moderately prominent varices. Spiral sculpture consists of seven prominent cords, with or without intercalary minor cords on the body, and two major cords and a single minor cord on the canal. A moderately heavy intritacalx, strongest on the shoulder, covers the surface of the shell, imparting a stark white color to fresh specimens. Deepwater examples show noteworthy open spinelets formed from the expansion of fine axial lamellae over the major cords, especially at the shoulder margin.
Shell color is brown-purple, with flesh-colored spiral cords. The apertural margin and denticles are blue-white, pale purple, or mauve more deeply within the aperture. Deepwater examples have white apertures with pale-pink suffusions.
