The exterior is sometimes most beautifully marked with transverse grooves, striæ, punctures, or granulations; the colour of almost every hue.
Shell turreted, sub-fusiform, and oval; the spire always pointed at the summit; the aperture small, triangular, wider and strongly notched anteriorly; the external edge sharp, almost straight, always longer than the columella, which is formed by a very thin callosity, and marked with oblique parallel plaits, of which those anterior are the shortest.
