Description

Shell forming a short cone with straight sides and a flat top. Colour white-transparent. Embryonic whorls intorted, of type C. Teleoconch consisting of about four, slightly convex whorls. Suture clearly marked. Growthlines strongly pro-socline. On the initial whorls a few spirally incised lines are sometimes discernible; apart from that the surface is smooth. Outer lip thin. Only a slight umbilical chink is sometimes present. There is a small but distinct columellar tooth.
Dimensions: H. 1.4-1.5 mm, W. 0.6-0.7 mm; holotype: 1.4 x 0.7 mm.

Interchangeable taxa

This rather common species looks somewhat like some forms of O. turrita Hanley, 1844, but it has an intorted protoconch instead of the helicoid protoconch of that species. O. striolata Forbes & Hanley, 1850, is also somewhat similar, but much larger and less slender.
Depth range.— 60-400 m.
