| D. Fehse and Z. Vicián 2004 | The shell is medium-sized, and rather squat, and it is an inflated pyriform, with a produced, blunt anterior terminal and a short, curved and slightly indented posterior terminal. The terminals are slightly separated from the dorsal elevation by a small indentation. The spire is rarely exvolute, and it is just above the bulge of the anal canal, being usually obsolete and covered by thick terminal callus, marked by a spiral sulcus. The dorsum is convex with the highest elevation at the posterior third and with the apex placed on the right side, with smooth, margins and strongly thickened by callus. The marginal callosity forms a distinct and rounded keel on both sides. The ventrum is weakly convex. The aperture is sinuous, being curved posteriorly with parallel edges. It is relatively narrow, and is slightly wider at the fossular section. The labrum is thickened and expanded in the medial portion, and it is slightly decline at the anterior portion. The inner margin has a sharp edge with 19-22 somewhat coarse, close-set, regular labral denticles. The latter are extended as folds onto the ventrum. The parietal lip is weakly denticulate 14-20 well-developed denticles. These weaken with so that the denticles on the medial portion are only slightly visible. The denticles strengthen again slightly on the posterior third. The denticles do not extend as folds onto the columella but onto the fossula within the aperture. The terminal fold is marginal and borders the siphonal canal where it is weakly strengthened to form a narrow keel. The subsequent columellar teeth are followed by a slight interstice. The fossula are usually flattened, very steep and they are not clearly delimited from the rest of the columella, which has 3-6 irregular denticles on its inner edge. The anterior border is formed by the continuation of the terminal fold. Here the terminal fold is projected at the anterior corner of the fossula. The anterior margin of the fossula is free and it is not fused with the inside of the dorsum.
Some specimens show remnants of a small red-brown spire blotch and several show remnants of a red-brown fine dorsal mottled pattern, whereas the margins and the ventrum are white. |
