Etrema kaipara

General description: 

Shell of moderate size, fusiform. Spire slightly taller than height of aperture plus canal. Whorls 44, exclusive of protoconch, which is incomplete, but evidently of about three smooth whorls, the last keeled. Whorls angled above middle, more strongly on body-whorl. Base quickly contracted to a long straight neck. Axials broadly rounded, slightly oblique, extending from upper suture to neck, 13 on body-whorl. Spire whorls with two pimary sharply raised spiral cords and three secondary ones, one above upper primary, one between the primaries, and the third just above lower suture. Four weak spiral threads on shoulder. On the body-whorl, base and neck, there are 22 spirals, closely spaced on neck but relatively strong. Aperture narrow, oblique. Outer lip heavily variced but thin on the inner edge. Sinus occupying shoulder, deep and rounded, rendered subtubular by a thick entering parietal callosity, bearing a strong tubercle. Columella with four rather distant strong tubercles. Inner edge of outer lip bearing six tubercles arranged in pairs on three prominently raised callus patches. Anterior canal moderately long, narrow and slightly oblique.

The status of this taxon was revised by Powell 1966 to doubtful [pg 112].
