Description

(composite; from Thiele's German description and Barnard's supplementary notes) —Shell small, 12.5 mm. (ca 1/2 inch) in height, fusiform, spire slightly taller than aperture plus canal. Whorls 6,5, including a blunt smooth dome-shaped protoconch of about 1,5 whorls. Shoulder area smooth, slightly concave and rather narrow, bounded below at about three fourths whorl height by an angulation formed by the abrupt termination of numerous linear spaced very protractively oblique fold like axials which continue strongly to the lower suture but do not extend over the base. Axials 15 on early whorls, increasing to 18-20 on the body-whorl (Barnard). Spiral sculpture consisting of faint spiral striae, crossing the axials on the spire-whorls and about 8 distinct threads on the neck and anterior end. Colour white. This species falls readily into Comitas since it is fusiform, with a blunt smooth paucispiral protoconch and post-nuclear sculpture of protractively oblique axials, stopped above by a smooth shoulder area, site of a broad but deeply arcuate sinus.
