Diagnosis
provided by World Register of Marine Species
Shell up to 25 mm high, fusiform, with moderately high spire. Protoconch of 3-4 smooth whorls. Teleoconch sculpture of low, rouned spiral cords, narrower than the intervening spaces, somentimes wit a smaller cord intercalated, and of broad axial folds which reach very far abapically on the body whorl. The first teleoconch whorls have only 2-4 cords, one of which tends to form a shoulder which is lost on te later whorls. Aperture strongly thickened externally and internally, the inner rim with 4-5 rounded denticles; columella sometimes also with 1-2 faint knobs delimiting the siphonal canal, which is short and broadly open. Colour whitish with reddish-brown lines running on the larger cords and with large, blurry brown blotches along the periphery of the body whorl.
