"Olivid with a solid, elongated fusiform shell, with a remarkable depression around the last suture, with two brownish orange bands in sub-sutural, fasciolar and basal bands on grayish brown ground, with small protoconch and spire-sheath forming a false suture. Aperture narrow, and with operculum having terminal nucleus. Description: Shell elongate fusiform, with depression around last suture, with two brownish orange color bands in subsutural and fasciolar bands on grayish brown ground. Spire consists of protoconch and five spire-sheath forming false suture. Protoconch exposed, rather small, hemispherical, with nucleus hidden. Spire-sheath faded in color but partially tinted by brownish orange as same as subsutural band on upper margin. Subsutural band with remarkably deep depression indicating suture formed by primary callus developed from the columella pillar forming narrow and thick pad-like deposit which never exceeds posteriorly the margin of this band. Middle zone light brownish orange, with fine axial lines crossed by very fine spiral striae, delimited by the margin of subsutural band posteriorly and fasciolar band anteriorly, with a white band in front of fasciolar band and lacking ancillid band and labral denticle. Fasciolar band delimited by raised margin of basal zone, with microscopic granules. Basal zone narrow, dark brownish orange in color, delimited by a furrow came from twisted columela pilllar with 4-5 folds. Aperture narrow, pointed at posterior canal. Outer lip moderately thick, simple anteriorly, white inside, tinted brown color on the margin. Operculum sword-like in shape, with terminal nucleus. Radula with three cusps in the middle part of central tooth, with strongly curved basal plate. Measurements (mm): length 38.6; width 13.0; aperture length 22.4 mm.". Recent.
