Depressiscala scipio (SYNONYM): Shell livid flesh-color, brilliantly polished, smooth, with nine to fifteen whiter thin low varices, curved and appressed at the suture, where they are slightly expanded; here and there one is of double size. The varices are often but not always continuous; the whorls are rounded, ten or fifteen in number, of which three, hardly distinguishable from the rest except by their paleness, are nuclear ; mouth ovate, lip thin, narrow, reflected; base rounded without a disk or cordon; suture distinct but partly filled by the expanded tips of the appressed varices. Lon. 16.0 mm, max. lat. 4.0 mm.

Small, about 14mm, with 10-12 whorls and an angle to spire of 20-25 degrees. White to tan or reddish brown in color. Axial sculpture consisting of 12-14 costae, low, reflected, with tiny angles or hooks at the shoulder. No spiral sculpture and no basal ridge. This species occurs from low water to about 65 fathoms. It is found from off the coast of North Carolina, south through Florida to the Bahamas and as far south as southern Mexico. This is not a common species.

This is the most slender recent species I have seen, and is readily recognized by its livid pink color, glassy polish and thin varices, compactly rolled spire, and absence of umbilicus, fasciole, or disk on the base. It is nearest to S. aciculina Hinds, but still more slender and drawn out.
