Suture shallowly impressed, subsutural ramp broad, concave, on last whorl weakly concave. Subsutural region with a row of distinct, dense, narrow, short, prosocline axial wrinkles, corresponding to upper parts of thickened growth lines, extending from suture to upper ⅓ of ramp, increasing in number from 22 on first whorl to 42 on penultimate and 50 on last whorl.

Cords closely spaced with intervals about half the width of cords. On last whorl cords covering entire shell surface below indistinct shoulder, about 40 cords in total, of which 20 on canal. Cords weak, slightly wavy, very closely spaced just below suture and with intervals 0.5–1.0 times cord width on shell base and canal. Shell base gradually narrowing towards narrow, nearly straight siphonal canal. Aperture narrow, constricted posteriorly, with narrow, moderately thick parietal callus, outer lip partially broken, evenly convex and weakly concave at transition to canal. Anal sinus shallow, subsutural, broadly arcuate, confluent with large forward extension of outer lip as deduced from growth lines. Shell off-white, with slightly darker subsutural ramp, protoconch light tan. Periostracum smooth, retained between cords and ribs.
