Material. 2 complete specimens and 4 fragments from layer 3.
Description. The shell is round-triangular in shape (HS is 34.1 mm; WS is 26.1-30.1 mm, average 28.1; WS/HS average is 0.9), consists of 5-6 rounded whorls, separated by a shallow suture. Convex, thick ribs are observed on the shell surface. The last whorl is bulbous (HLW/HS is 0.95). Spire is high and has a cone form, consisting of convex whorls. Umbilicus is closed by the inner edge of aperture. Aperture is rounded, large, pointed in the upper part (HA is 15.4-17.2 mm, average 16.2; WA is 13.4-14.0 mm, average 13.7; WA/HA is 0.8-0.9, average 0.85) and is about 1/2 of the total shell height (HA/HS is 0.5). Aperture edges are thickened. Spiral growth lines that coincide with ribs are visible on the shell surface.
Remarks. This species was described by Toula (1892) as Turbo barboti , but he also used the same name for almost smooth forms from Bulgaria in 1877. As a result, Kolesnikov (1935) used the name “intermedia ” for ribbed forms, proposed earlier by Radovanović and Pavlović (1893).
Region of distribution and age. Sarmatian of the Eastern Paratethys (O. Anistratenko and V. Anistratenko, 2012).
