DESCRIPTION.—Shell (Figures 125, 126): Shell slender, turreted, comprising 11–14 convexly angulate whorls, and reaching 27.2 mm length and 9.5 mm width. Protoconch (Figure 126D) 2.5 whorls, smooth, with moderate sinusigeral notch. Early teleoconch whorls with broad, sloping, subsutural ramp, and sculptured with two spiral cords. Adult teleoconch whorls sculptured with 12–16 axial ribs crossed by 2, sometimes 3, major, spiral, nodulose cords, with single minor subsutural beaded, spiral cord and one minor presutural beaded cord varying in size; many, fine, spiral lirae on interspaces. Large, angulate varices randomly distributed. Two major spiral cords at whorl periphery, frequently nodulose and angulate. Suture distinct, slightly wavy. Body whorl sculptured with 5 beaded or nodulose spiral cords, and with moderately excavated base sculptured with 5–7 weaker spiral beaded cords extending down anterior siphonal canal. Large varix on body whorl opposite outer lip of aperture. Aperture ovate, a little more than one-third the shell length. Anterior siphonal canal short, wide, well defined. Anal canal distinct, with strong parietal columellar tooth. Columella concave with strong callus and moderate columellar lip. Outer lip thickened at edge, strongly crenulate. Shell color white, sometimes tan, with brown spiral spots on nodes and beads, and with fine tan specks. Aperture and columella white. Measurements (Table 40). Periostracum thin tan. Operculum, thin, tan, paucispiral with eccentric nucleus.

Radula (Figure 127): Radular ribbon Type-1 (Figure 3A) small about one-tenth the shell length. Rachidian tooth (Figure 127B,C) with triangular shaped basal plate with long posterior projection and pair of basal ridges; anterior front lightly concave; cutting edge with large, triangular, central, main cusp flanked on each side by two very small denticles. Lateral tooth (Figure 127B,C) having long, lateral, posterior projection with long median buttress and small pustule, on broad basal plate; cutting edge of lateral tooth with one broad, main cusp, one inner denticle, and 2 or 3 outer, pointed denticles. Marginal teeth (Figure 127A–C) elongate, narrow, with tapered bases, and curved and serrated at tips. Inner marginal tooth with spatulate major cusp at tip and with 3 inner denticles and 2 outer denticles. Outer marginal tooth same, but lacking outer denticles.
