Later whorls are broad in relation to their height and have a ramp which becomes broader from whorl to whorl in most specimens. Below the ramp, a weak concavity (lateral view) is developed; rarely, the ramp remains narrow and the concavity is lacking. The last whorls of large specimens increase only slowly in width and this part of the shell is more or less cylindrical. The transition from whorl face to base is evenly rounded without edge or spiral cord. Aperture with two columellar and palatal plaits and one parietal plait.</paragraph>

<paragraph id="B7FAE90F01A6063500710FE70794222E" pageId="0" pageNumber="179">A large specimen (early whorl missing) is 33 mm high. The early shell is very slender consisting of at least eight smooth whorls having a weakly convex whorl face and somewhat impressed sutures. The following 2-3 whorls increase rapidly in width and are very wide in relation to their height. As a result, the spire is coeloconoid. In the mentioned 2-3 whorls following the slender spire whorls, a broad, distinctly concave, funnel-shaped ramp is formed. From now on, the ontogenetic evolution of the shell follows different pathways leading to two varieties (morphotype 1 and 2 as well as to intermediate forms).</paragraph>

<paragraph id="4F4BD4A330AD8172F9F64E158AF4F6B7" pageId="0" pageNumber="179">In morphotype 1 (much more abundant than morphotype 2), the wide ramp continues and becomes wider. It is delimited from whorl face by a broad concavity with indistinct borders. Initially, the whorls continue to rapidly increase in width. In large, more or less fully grown specimens, the increase in width decelerates, the last whorls are high and almost cylindrical in shape. The edge of the ramp is projecting abaxially and forms the whorl periphery.</paragraph>

In the other extreme form, morphotype 2, the rapid increase of the width of the whorls and the formation of a broad ramp is confined to 2-3 whorls. Afterwards, the whorls become wider and increase in width only slowly, but considerably increase in height. The ramp forms only a narrow band. The whorl face is straight and lacks a concavity below the ramp so that this part of the shell is almost cylindrical. As mentioned, there are transitional forms between varieties 1 and 2 (Plate

Base and whorl face are smooth. The base has a distinct umbilicus. The growth lines run straight and somewhat opisthocline on the whorl face and curve strongly backward below the ramp. The aperture is very narrow, adapically acute and has a weakly developed siphonal canal. The inner lip is broadened and detached in the columellar area; it partly covers the umbilicus. The inner lip bears a strong parietal and two columellar plaits. The adapical columellar plait is weaker than the abapical one. The aperture has two palatal plaits which are, however, rarely recognizable.</paragraph>
