Esmeraldas Province, Ecuador. Onzole Formation. Height mm. width mm. 1, from view; 2. rear view; 3. from right side. orthocline to slightly opisthocline axial ribs per whorl. Axial ribs more or less alined on successive whorls. Interspaces of axial ribs slightly concave, sculptured by three to seven flat topped spiral riblets on spire whorls, which usually are subdivided centrally by an incised line. The spiral sculpture is crossing the axial ribs not only on the body whorl but also on the spire whorls. Suture not deep. Aperture moderately narrow. Outer lip thickened. Sinus adjoining suture moderately deep. Inner surface of outer lip smooth, but with a ridge parallel to the sharp edge of the outer lip ex- tending from the sinus to the beginning of the anterior canal. Columellar and parietal calluses moderately prominent. Anterior canal almost straight and short. //o/onyjf.—USNM 644221 (Text-fig. 10). Dimensions of holoType.—Height mm. width mm.
