15 mm

Very narrow fusiform. Point of protoconch broken, and apical whorls corroded; 7 postnatal whorls remaining. Profile of whorls evenly convex, no shoulder. Growth-lines for the most part distinct, somewhat variable but not forming axial ribs, strongly protractive on sulcus before passing over on to -whorl. Fine spiral lirae 4 on 4th whorl, 6 on 5th, 8-9 on 6th and to on 7th, on base c. 15 additional lirae but not well defined on rostrum. Columella sinuous, canal long, narrow. 15 X 3.5 mm. White, glossy except where corroded.

Larger syntype (15.2 x 3.4 mm) with broken aperture, partly broken penultimate whorl. Smaller syntype (13.6 x 3.3 mm) here designated as lectotype. Shell very narrow, semitransparent. white, very fragile. consisting of 7.5 whorls, uppermost whorl(s) missing. Upper 3 whorls with eroded surface, differing in their proportions from subsequent whorls, apparently representing a protoconch. Teleoconch whorls rather evenly convex, with clearly defined subsutural ramp, bordered by spiral cord corresponding to lower, almost horizontal branch of anal sinus. Spiral sculpture developed below subsutural ramp, consisting of weak narrow cords separated by wide (2-3 times wider than cords) interspaces. Cords weaken on shell base with smooth band at transition of shell base to canal. Sculpture resuming on canal but with very weak cords. Siphonal canal long, narrow, twisted. Anal sinus subsutural. not very broad. Outer lip projects forward below anal sinus. Paralectotype differs only in having slightly more numerous and more closely spaced spiral cords (12 on the penultimate whorl vs. 11 in the lectotype).
