No description, only figure.
"Shell oval with the spire very short; early whorls flesh-colored, later ones pale brown, the last with vermiculations, arrow-shaped markings and dashes of yellowish-white, the points of the arrows being protractively directed; the interior of the outer lip is mottled at the edge, and brownish-flesh-colored within. The first 3 whorls form a mucronate apex, the next 3 expand very rapidly and are separated by a rather deeply impressed channeled suture; the last whorl is marked by fine retractively slanting, incremental fines and microscopic spiral striations. Suture channeled. Base moderately long with a single impressed line a little anterior to the periphery; the parietal and basal callus are marked by folds of which the first two are slender, and these are about one-fourth of the length of the aperture anterior to the posterior angle of the aperture; they are followed by a heavy fold which in turn is followed by two a little less conspicuous, succeeded by a narrower one which is followed by 2 heavy folds which in turn are followed by 2 a little less strong; the outer lip is thin; the aperture is narrowly channeled posteriorly and deeply notched anteriorly. The type has almost 7 whorls, and measures — length, 10.7 mm.; greater diameter, 5.2 mm.". Recent. Salinas, Guayaquil Bay, Ecuador.
