Diagnosis
ReferenceDiagnosis
D. Fehse and B. Landau 2001Shell medium sized, relatively fragile, elongated pyriform, with an elevated, somewhat pointed spire. Protoconch mostly covered by callus, but visible in several specimens; consisting of 2 Y. convex whorls, with a small nucleus. The first protoconch whorl is elevated, the second becoming depressed. Suture clearly marked and incised. Junction with teleoconch obscured by callus. Teleoconch consisting of about 3 whorls. Spire covered by very thick callus, which covers the suture. Body whorl 80% of total height, shouldered adapically, with the maximum diameter 114 distance from the adapical suture, evenly tapered below and only slightly constricted at the base. Dorsum smooth, rounded, with the dorsal sulcus reduced to a small dimple behind the anterior extremity. The whole shell surface covered by thick, smooth, glossy callus. Aperture comprising about 75o/o of total height straight and narrow. Outer lip thickened, smooth, basally flattened with an angular outer margin, bearing 19-23 strong, regular, knob-like denticles, which extend onto the lip to a variable distance. Siphonal canal short, rounded and straight. Columella almost straight, with a well-developed rounded carina} ridge. Outer edge of columella delimited by a row of 17-22 denticles, becoming weaker adaxially. The most anterior 5 denticles are developed into folds, which run obliquely across the base. Fossula deeply concave, but not delimited from the columella. Tenninal ridge simple, short and strongly developed.
