Shell slender, acute, rather flat-sided, purplish brown usually more or less obscured by a yellowish white glaze; nucleus with the first turn smooth, inflated, the second has a peripheral keel and is followed by about eight and a half subsequent whorls; suture strongly appressed with a smooth narrow band in front of it and behind the somewhat constricted fasciole; other spiral sculpture of sharply incised lines, four or five on the spire between the sutures, equal and with wider equal rounded interspaces, and about 24 on the last whorl, the interspaces becoming more cord-like near the canal and sometimes feebly nodulous where the lines cut the ribs; axial sculpture of (on the penultimate whorl about 18) feeble narrow ribs, stronger near the apex, obsolete on the last whorl, with wider interspaces, beginning in front of the fasciole, hardly reaching the base, and protractively oblique; there are also fine sharp incremental lines, chiefly evident in the depressions, but here and there finely reticulating the interspaces; aperture rather wide, anal sulcus conspicuous, rounded; outer lip thin, prominently arcuate, smooth within; inner lip with a thin layer of brownish enamel, the edge raised anteriorly; canal distinct, slightly constricted, with a small concentrically striated siphonal fasciole. Height of shell, 18 mm.; of last whorl, 10 mm.; diameter, 6 mm.
