Shell moderately large, 30-40 mm, solid, narrowly elongate-biconic, with a rather short turreted spire, and a very long narrow body-whorl, gradually tapered to a weakly differentiated short shallowly notched anterior canal, with a low inconspicuous fasciole. Protoconch small, erect, papillate, of two smooth shining whorls, the first planorbid and the second globose, developing very faint spirals towards its close. Adult whorls with a strong sutural fold, a relatively wide shoulder sulcus and a bluntly rounded submedian peripheral keel. The shoulder sulcus bears weak spiral threads but from the periphery downward and over the entire body-whorl to the anterior fasciole, the surface is cut into rather broad flattened spiral cords by linear grooves. The whole crossed by axial sculpture, which renders both the sutural fold and the peripheral keel somewhat nodulous, and cuts the remaining spiral cords into squarish gemmules. Aperture very long and narrow. Outer lip thin, descending rather straight, but interrupted above by a moderately deep U-shaped sinus, with a rather widely divergent approach, its apex on the lower part of the shoulder sulcus. Inner lip long and straight without processes and lightly callused. Colour yellowish-brown to diffused rusty-brown. Radula toxoglossate, a pair of lanceolate marginals, tapered to a very narrow point, minutely barbed at the tip, and with a knuckle-like base.
