). Teleoconch thin and fragile, translucent, thickened where ribs or keels occur. Whorls highly convex, inflated for its genus. Suture distinct, well defined, impressed. Spiral sculpture of 2 or 3 very strong, sharply raised, approximately equally-spaced blade or flange-like keels, positioned at shoulder, mid-whorl, just above suture. Some individuals lack shoulder keel; other 2 always present. Three additional weaker spiral ribs present anterior to suture. Axial sculpture of 14-18 regularly spaced, raised ribs running from suture to suture, approximately equal in strength. Together two directions of ribs intersect to form regular reticulate sculpture of regular rectangles. Nodes drawn out on spiral keels where intersection with axial ribs occur, resulting in undulated edges, on shoulder keel these develop into short spines. Aperture semicircular, taller than wide. Columellar variable from straight to sigmoidal. Siphonal notch distinct, shallow. Apex decollate, heavily corroded, leaving only 1.5-2.5 whorls of teleoconch whorls. Incompletely corroded periostracum present around apex, darkened in colouration. Secondary plug-like calcareous secretion present at apex, preventing exposure of visceral mass. Growth lines indistinct. Protoconch unknown, as all specimens examined had corroded spire.
