Species / Persististrombus Pannonicus
Stromboidea
Original Description of Persististrombus pannonicus by Harzhauser & Kronenberg, 2013, p. 795:
- "Bulky robust shells with pronounced sculpture. The height ranges around 80–100 mm; the spire is broad with an angle of c. 60–70°. Nodes appear already on the penultimate spire whorl and grade into prominent spines on the last spire whorl. Early spire whorls are covered up to their middle by the following whorl, often forming a wavy sutural band, which covers the spines up to just below their tips. On later spire whorls, the suture is gradually shifting slightly below the tips of the spines but the following whorl covers always the base of the spines. The spines of the last whorl are very irregular in shape; they are axially elongate at their base, much higher than wide in cross section, and often display concave areas along their flanks. They are deflected leftwards in apical view and point in adapical orientation. Aperture moderately wide with broad sinuous adapical tip which is attached to the suture; outer lip thickened with straight sided or sigmoidal margin. Shell surface of adult shells smooth; only subadults display weak spiral threads."
