Description (Gittenberger et al, 2000):
Shell: Very fragile, elongate-conical, creamy white; reaching 8.5 mm in length. Length/width 2.0-2.3-2.7. Protoconch whorls 3.25. Protoconch with numerous very fine, incised, axial lines. Maximum protoconch 1 diameter 0.12 mm (n=1). Teleoconch whorls up to 8, separated by a very deep suture. Teleoconch sculpture with evenly spaced, orthocline, lamellate costae, crossing low spiral threads that are approximately a half to a fifth as wide as interspaces. Reticulate pattern present on most adapical whorls, replaced by spiral threads on later whorls. Third whorl with ca. 13 spiral threads, fifth one with ca. 15; spiral threads equally prominent throughout whorl. Costae unually not continuous, lamellar, but rather low, barely touching preceding whorl. Due to damage in most specimens, fine structure of costae could not be examined. Fifth teleoconch whorl with 24-25-26 costae and 12-13-15 spiral threads. Aperture subcircular. Apertural length/shell length 0.22-0.23. Umbilicus absent. Egg-capsules roundish, white, mixed with sand, closely connected along a straight mucous thread.
