|---|---|---|
| D. Fehse and J. Grego 2012 | Shell medium sized, relatively fragile, elongated pear-shaped, with an elevated, rounded spire. Protoconch mostly covered by callus, but visible in several specimens. It consists of 1 to 1% depressed whorls and a very minute nucleus. Suture faintly visible. Teleoconch consists of almost four whorls. Spire covered by thin callus hiding the suture. Body whorl almost 80% of total height, rounded adapically, with the maximum diameter at * of the distance from the adapical suture, evenly tapering below and slightly constricted at the ventrum. Dorsum usually smooth and rounded. Dorsal sulcus represented by at least a dimple behind the anterior extremity in fully adult specimensAperture comprises c. 75% of total shell height, almost straight and fairly narrow. Labrum thickened, smooth, somewhat flattened and sloping slightly into the aperture, rounded at the outer margin, bearing 12 to 15 coarse teeth of irregular strength, which extend slightly onto the labrum. Siphonal canal short, indented, rounded and straight. Columella almost straight, with a weakly developed inner carinal ridge and a rounded parietal lip. Columellar denticles coarse, varying from 10 to 12 in number. Anterior 1-3 denticles are developed as short folds, running obliquely across the ventrum, the remaining ones weakly developed or obsolete. Fossula not delimited from the columella. Inner fossular margin slightly protruded. Terminal ridge biplicate.
Range of variation – Sometimes the shell is somewhat pustulated. The shell inflation varies and the shell outline is more or less pyriform. The development of the labral folds vary. |
