This species was found intertidally on and under rocks in a habitat with fine, pale muddy sand. About 60 were collected; they occurred more densely than similar species where they were found and tended not to be mixed with other small columbellid species. Three adults were sectioned (one male, two females with one female cross sectioned, one longitudinally sectioned), three males dissected.

measured. Adult shells with 4 to 5 teleoconch whorls (avg. 4.3). Protoconch smooth, white, with 3 to 3.25 whorls and no real sinus. Predominant sculpture consists of rounded, slightly sinuous axial ridges (16 to 19 on the body whorl), with spiral grooves between ridges on the spire whorls and often on the body whorl. A weak subsutural groove cuts across the tops of the axial ridges. Shell translucent, white. Spire whorls have a single band of wavy axial chestnut makings in the middle of the whorl, with an additional row present on the basal half of the body whorl. These form two large blobs on the outer lip. Tip of siphonal canal in adults dark purplish brown. Aperture white. Aperture edge thickened, denticulate, with a shallow posterior notch. Parietal wall with a ridge of denticles.

E): In four adult male specimens dissected, lateral teeth 28 to 34 µm long by 12 to 15 µm wide, with rectangular center plates. Two radulae that were complete had 137 and 155 tooth rows. Lateral teeth have three pointed secondary cusps, the bottom one pointed and curved down, and separated from the distal two by a wide gap.

: Male reproductive anatomy typical for the genus. Primary seminal vesicle coiled, contains both pink staining and typical dark staining sperm, with a low epithelium overall. Spermiduct gives off short mantle cavity duct adjacent to the kidney. Anterior spermiduct embedded in the body wall has a thin coat of circular muscle. Anterior spermiduct enters hemocoel near penis base and forms a long loop adjacent to the proboscis. The loop has a complex pale purple-staining mucoid epithelium that continues into the penis base, after which the duct becomes non-secretory. Penis tip densely supplied with subepithelial mucus cells. Penis long and very narrow, with a short filament tip (as in
