Description.
Shell brownish corneous or yellowish, slender turriform, widest at its base; there are 10.25 (n=2) regularly increasing whorls; first whorl of the protoconch rather smooth, the second whorl is finely ribbed; suture deeper on the upper whorls, especially at the protoconch; the coarse riblets are regular on the whole shell; keel blunt, the ribs of the body whorl are visible here too, especially close to the end of the keel (close to the columellarparietal transition of the peristome); there are rather shallow sutures on both sides of the keel where it joins the shell surface of the last whorl; keel starts from the back side of the most basal point apertural rim, and ends on the ventrolateral side; keel gradually becomes lower towards its end; there is a second, lower keel between the main keel and the umbilicus; it also starts from the back side of the apertural rim; main keel visible inside the aperture as a shallow canal; aperture round with angled columellar-parietal and parietal-palatal transitions; the lower incision (basal part of the aperture) is the starting point of the keel; apertural rim thickened and very much reflexed.
