), slender with a high, acutely pointed spire composed of flat to convex whorls having a concave anal sulcus below the suture. Aperture narrowly oval, only slightly wider at its widest than the anal sinus and canal at opposite ends. Anterior canal well demarcated and of short to moderate length, and a weak to strong anterior fasciole with or without a weak false umbilicus, or chink. Protoconch of 23 smooth whorls. Sculpture of numerous ridged axial ribs (crests narrow, not round) that extend from suture-to-suture but are greatly reduced and recurved in the sulcus giving the shell a shouldered or turreted outline in most species; ribs either straight or slightly opisthocline. Varix hump-like in most, positioned ¼- to ⅓-turn from the outer lip. Strong spiral sculpture of incised grooves that create the appearance of bands, cords or threads that override or cut the axials. Outer lip thin, flattened from varix to lip edge, strengthened by irregular axial folds, with a stromboid notch anteriorly, and anal sinus posteriorly; edge of lip may be scalloped or “toothed” by spirals, or not. Inner lip margined, recumbent or erect, usually relatively wide; with a callus on the parietal wall at the anal sinus. Anal sinus deep, U-shaped, adjacent to the suture, offset from shell axis by parietal lobe and projected laterally so that it appears spout-like.
