Diagnosis
ReferenceDiagnosis
S. N. Nielsen and D. Frassinetti 2007Shell massive, biconical to subglobose. Aperture about twice as high as spire. Protoconch unknown. Teleoconch of five to six shouldered whorls. Broad concave subsutural ramp. From third teleoconch whorl onwards very strong, long nodes are developed, seven to nine per whorl. Suture adpressed, on early whorls often on nodes of previous whorl. Regular flattened spiral cords over whole teleoconch, 22 to 31 on spire whorls, on later whorls becoming restricted to subsutural ramp, secondary threads occur irregularly. Interspaces equal to slightly narrower than spirals. Aperture elongate-oval. Outer lip thickened, interior smooth, lower half flaring. Posterior notch present. Columella straight, on lower end slightly twisted to the right, bearing two to three folds. Thin to heavy parietal callus present. Last whorl constricted, forming a short, straight, wide, open siphonal canal. Fasciole very prominent, restricted above by ridge. Height up to 125 mm.
