| N. D. Banjac et al. 2007 | (according to AKOPYAN, 1976). The shell is conical with a high spire. Whorls are slightly convex, with two major keels. They frequently bear tubercles and give the whorls an angular shape. The suture is well expressed. Ornament may also consist of additional weak spiral threads. The area between the keels in the central part of the whorls is flattened. The base is convex with a narrow umbilicus. The aperture is rounded and has a wide and deep sinus at its outer lip. |
