| Reference | Diagnosis | |
|---|---|---|
| D. Fehse and B. Landau 2002 | Shell medium sized, relatively fragile, inflated, pyrifonn with a short, conical spire. Protoconch consisting of 1 lf2 ... 13/4 somewhat elevated, convex whorls with a small nucleus. Junction with teleoconch clearly defined, with a constriction in the junction area.
Teleoconch comprising 4 flat-sided whorls, covered by very thin callus, suture distinct but superficial. Body whorl about 80-90o/o of total height, inflated, shouldered adapically, with the maximum diameter just below the adapical suture, convex below and strongly constricted at the base. Dorsum smooth, rounded, without any dorsal sulcus and strongly constricted behind the anterior extremity. A thin callus covers the entire body whorl, which is usually eroded. Aperture wide and straight, 70-80o/o of total height. Outer lip weakly thickened, bearing 11-15 subequal denticles on the inner border, which do not usually extend onto the lip. Siphonal canal short, rounded and straight. Columella smooth, straight, bordered internally by a weak carina} ridge. The outer border delimited by a ridge in the anterior portion, which may bear 1-5 weak denticles. Fossula marked by a weak concavity. Tenninal ridge simple and strong, running along the border of the siphonal canal. |
