Shell brilliant white, with a trochoid brown glassy nucleus of four whorls, the last of which has a sharp peripheral keel; subsequent whorls seven, with a peripheral row of (on the last whorl 14) short prominent subnodular waves which on the last two whorls tend to become a little elongated and oblique ; they do not form ribs or pass on the last whorl before the periphery; between them and the suture the whorl is excavated somewhat and marked with very fine spiral grooves crossed by the arched incremental lines; over the nodules run a few small spiral threads, strongest on the early whorls ; on the base are five or six flattened threads with wide interspaces, on the canal are about a dozen smaller threads, closely set; the whole surface appears polished and the fasciole smoooth ; notch deep and wide, abutting on the preceding whorl at the suture ; outer lip arched forward about a quarter of a turn, thin, simple ; inner lip smooth, pillar short, obliquely twisted; canal wide, distinct, flaring at the end, slightly recurved ; aperture narrow, shorter than the spire. Max. lon. of shell, 13.75 mm ; of last whorl, 8.2 mm ; lat. of shell, 6.0 mm.

Shell high, slender, light yellow, reaching 23.1 mm. Protoconch with 3 whorls, dark yellow. Protoconch 1 slightly darker and granulose. Protoconch 2 with a spiral keel on its lower portion and a delicately nodulose suprasutural cord. The spiral keel itself is sculptured with tiny slanted riblets, giving it the appearance of a braid. Clear-cut protoconch-teleoconch transition. Teleoconch with about 8 middle-angled whorls. The middle shoulder bears large rounded axially elongated nodules, about 14 on the 7th whorl. The spiral sculpture consists of 6 very thin lines, the upper one right above the shoulder and the others spreading equidistally towards the lower suture. The entire shell surface is covered by axial growth scars and microscopic, spirally arranged granules. Suture shallow. Base convex, inflecting to form the siphonal canal, with about 17-20 spiral lines. Labial sinus deep, curved at the zone between the shoulder and the upper suture. Inner lip whitish and reflected. Outer lip thin. Siphonal canal long and narrow. Aperture elongated.

Though small, this is one of the most elegant of the American species, and does not accord in the details of its sculpture with any other known to me.
