Description
editThe shell is 9 mm long and 3.5 mm in diameter. It is nearly smooth and porcellaneous. The spire is slightly shorter than the narrow aperture. The protoconch consists of three smooth convex whorls, then a half whorl finely and closely ribbed. Three and a half subsequent whorls consist in sculpture of narrow, slightly oblique ribs which pass across the spire-whorls between sutures. On the body whorl, eight follow down the anterior canal to its tip. The spaces between the ribs are wide, flat and smooth. The tops and sides of the ribs are etched with fine subobsolete spiral lines. The aperture is linear-elliptical. The outer lip is somewhat thickened by the last rib, and smooth within. The anterior canal is long and straight.[1]
Distribution
editThis fossil was found in the Gatun Stage of Pliocene strata in Costa Rica.
