As Discopsis turtoni Bartsch:
Shell small, discoid al, semi translucent, bluish white. Nuclear whorls one and one-half, smooth, well rounded, forming a depressed helicoid spire with strongly impressed sutures. Postnuclear whorls two and one-fifth, broad, well-rounded, with strongly impressed sutures marked on the upper surface by rather strong, decidedly, retractively curved lines of growth. Periphery of the last whorl acutely keeled. Base very widely, openly umbilicated, there being scarcely any external limit to the umbilicus, all the whorls showing within, A slender spiral cord encircles the base about one-fourth of the distance anterior to the periphery. On the base the lines of growth assume a thread-like appearance, becoming stronger within the umbilicus. The entire base is marked by microscopic spiral striations. Aperture very oblique, of irregular outline; outer lip thin, sinuous, showing the external markings within; inner lip decidedly flexuose , thin.
