Original description by Korobkov, 1949 (in Russian).

Крупная (высота до 57 мм), сильно расширяющаяся книзу, слегка изогнутая раковина, состоящая из 8 оборотов, разделенных глубоким узким швом. Последний оборот большой, несущий на поверхности 3 гранулированных киля, из которых нижний часто бывает совершенно гладкий. Поверхность более ранних оборотов покрыта спиральными ребрышками, количество которых колеблется в пределах от 15 до 18, пересеченными поперечными так, что образуется характерная сетчатая скульптура. На поздних оборотах сетчатая скульптура неотчетливая, вследствие сильного развития спиральных ребер. Устье узкое с 3 характерными пальцевидными отростками наружной губы. Верхний отросток, приросший по всей длине поверхности оборотов, у некоторых экземпляров значительно выступает над спиралью раковины. Второй, изогнутый отросток под углом в 50–70 ° к первому направлен вбок и вверх, а нижний прямолинейный отросток примерно под таким же углом к предыдущему — вбок и вниз. Верхний сильно бугорчатый киль поверхности последнего оборота в виде грубого гладкого ребра продолжается на среднем отростке, а средний киль — на нижнем. Пальцевидные отростки с внутренней стороны несут узкие каналы, открывающиеся в устье.

Original description by Korobkov (1949) (translation Trubin, Wieneke).

Large (height up to 57 mm), strongly expanding downwards, slightly curved shell, consisting of 8 whorls separated by a deep narrow suture. The last whorl is large, bearing 3 granulated keels on the surface, of which the lower one is often completely smooth. The surface of the earlier whorls is covered by axial ribs, the number of which ranges from 15 to 18, crossed by transverse ones so that a characteristic reticulate sculpture is formed. On later whorls, the reticulate sculpture is indistinct due to the strong development of axial ribs. The aperture is narrow with 3 characteristic finger-like digitations of the outer lip. The adspiral digitation, grown along the entire length of the spire, in some specimens protrudes significantly above the spira. The second, curved process is directed laterally and upwards at an angle of 50–70 ° to the first one, and the lower rectilinear digitation is directed laterally and downwards at approximately the same angle as the previous one. The upper, strongly tuberculate keel of the surface of the last whorl, in the form of a rough, smooth rib, continues the middle digitation, and the median keel continues the lower digitation. The finger-like digitations on the inner side bear narrow canals that open at the aperture.
