The shell is large (maximum length 32,5 mm), robust, and broadly fusoid. The spire is high, consisting of one and one-fourth rounded nuclear whorls and seven or eight obliquely shouldered postnuclear whorls. The suture is moderately impressed and undulate. The body whorl is moderately large and broadly fusoid. The aperture is of moderate size and ovate, with a narrow, shallow anal sulcus posteriorly and a narrow entrance to the siphonal canal anteriorly. The outer apertural lip is thin, crenulate, and erect; its inner surface bears six to eight sharply, spirally elongate denticles, the anteriormost one at times double. The columellar lip is adherent posteriorly, expanding in this region into a moderately thick callus, detached and erect for the anterior two-thirds of its length; the posterior end bears two or three oblique pustules. The siphonal canal is moderately long, narrowly open, and slightly bent, if at all.
The body whorl bears five or six spinose varices. Spiral sculpture consists of four major cords, the two outer ones larger than the medial two, and numerous minor cords: three on the shoulder, two between the heavy shoulder spine and the next spine, single minors alternating with the anterior three majors, and five minors on the canal. Where the major and the strongest minor cords intersect the varices, straight, open spines are developed, their length varying with the prominence of the cord. Extremely fine axial growth lamellae produce microscopic scales over the spiral elements, the scales imparting a finely scabrous texture to the shell.
Shell ground color varies widely from uniform rust-brown, to rust-brown with darker-brown intervarices and cord interspaces, to pale violet-brown or yellow-brown. The apertural region is white, suffused with violet or pink, the same color staining all or the distal portions of the spines.
Known to us from the Andaman Islands region of the Indian Ocean in depths of 60-70 m.
