Biology Type of larval development: planktotrophic, inferred from multispiral protoconch. [details]
Diagnosis Shell up to 20 mm, elongate fusiform, quite solid. Protoconch of 3 1/4 whorls, high conical with blunt apex; protoconch whorls slightly convex, the first three smooth with a distinct suprasutural thread, the last 1/4 with strong, widely spaced arched folds parallel to the protoconch/teleoconch limit, and some very minute granules (visible only under SEM) in the intervals. Teleoconch of 6-7 whorls. Spire whorls convex, with maximum convexity near the suture of the following whorl, with 7 broad rounded axial ribs overrun by three spiral cords, the abapical one stronger. Body whorl with rounded periphery and a moderately long, straight, tapering siphonal canal, with 8-10 main spiral cords, more delicate spiral threads on the canal and ocasionally a spiral thread intervalated between two main cords. Aperture comma-shaped, with the parietal edge bearing anteriorly a strong fold and then forming a deep embayment where joining the columella; the columella with a convex part bearing four weak folds, then straight in its anterior portion. Outer lip with a thin edge, weakly denticulated at the termination of the spiral cords, thickened at some distance inside, with 6-7 raised spiral folds on the thickened part and continuing inside the shell.
Colour of protoconch plain brown, of teleoconch a pale greyish brown with contrasting yellow lines along the cords, dark brown intervals between cords on the ribs, all grading to a white siphonal canal; interior of aperture white.
