| D. Fehse and B. Landau 2001 | Shell medium sized, solid, pyriforn1, globose and squat with a very low, rounded spire. Apex covered by thin callus, under which a broad, bubbleshaped protoconch, consisting of 2 V4 whorls, is visible. The protoconch has a small nucleus with the second whorl very convex and rapidly expanding. The junction with the teleoconch is not clearly delimited, but the transitional area is much narrower than the preceding teleoconch whorl. Teleoconch of 2 straight-sided whorls, covered by thick callus, which obscures the suture. Body whorl 90o/o of total height, shouldered adapically, with the maximum diameter 1/4 distance from the adapical suture, rounded below and strongly constricted at the base. Dorsum smooth, rounded, without a dorsal sulcus, constricted at the anterior extremity.
The shell surface is covered with a heavy, smooth, glossy callus. Aperture comprising almost 80% of total height, straight and narrow. Outer lip smooth and thickened, with the outer margin evenly rounded, bearing 15-18 strong, irregular denticles, which extend onto the lip. The denticulate area of the outer lip tapers into the aperhlre. Siphonal canal relatively short, rounded and abaxially recurved. Columella straight and smooth, bordered internally by a relatively strong carina! ridge. The outer border bears a row of 17-19 denticles, strongest in the anterior portion, weak to subobsolete in the median portion, weak in the posterior portion. The most anterior 2 denticles are developed into strong folds, which run obliquely across the base. Fossula deeply concave and well delimited from the columella. Tenninal ridge simple and weakly developed. |
