Shell small, varying in shape from ovate to broadly ovate. The first nuclear turn is smooth, the next shows the beginning of the spiral cords of the postnuclear sculpture. Postnuclear whorls with a roundly sloping shoulder, which extends over almost half of the turns and terminates in a well-marked angulation. The whorls are ornamented by well developed, sigmoid axial ribs and almost equally strong spiral cords, the junction of which produce rounded tubercles. The spiral sculpture of the shoulder is usually weaker and more crowded than that on the rest of the whorls. Suture moderately constricted. Periphery well rounded. Base moderately long, ornamented like the spire, but with the sculpture a little finer. Columella stout, marked by spiral cords and slender axial threads. Aperture pear-shaped, strongly channeled anteriorly, with a weak sinus at the shoulder on the outer lip. Type: Venustoma harucoa, new species.
