Diagnosis
ReferenceDiagnosis
O. S. Adegoke 1977Small-sized, conical, thin-walled turritellid, apical angle about 25°. Protoconch small, bulbous and smooth; first two post-nuclear whorls gently convex, later whorl sides straighter. Five spirals appear almost simultaneously on the third spire whorl, they represent r, a, b, c, and d(.''). All five spirals subequal at first appearance with a, b and c later becoming more prominent than others; position of a migrates abapically during ontogency. Other spirals to a total of 11 develop on adult whorls; of these, two are adapical to a, three lie between a and b, and two fine threads occur in the excavated interspace between b and c, and one between c and the peribasal d.

Growth line inconspicuous, with a deep and broadly curved antispiral sinus with the deepest part on b, and a narrower sharply flexed spiral sinus with the major flexure on d. Suture well defined, impressed. Base plano-convex, ornamented by several fine spirals with finer threads in the interspaces. Aperture small, low, with an oval-trigonal outline.
