«Chlamys (Spondylopecten) stoliczkai: Cox, 1952, p. 15, pl. 3, fig. 17.
Description. Shell small, of rounded, triangular outline. Sculpture is of 20 rounded radial ribs. In size, ribs are consistent {firm}, except for the first and last three on the margins of the valve, which are narrower than the rest. On the slopes of the ribs a row of punctated {consisting of points} protuberances {bumps} is traced, formed as a result of the intersection of concentric sculpture and striae. Fine striation is observed on the surface as well of the ribs. Rib interspaces are narrower than ribs themselves.
Concentric sculpture is in form of fine lines, which curve on the surface of the ribs to the side of the beak. Comparisons and comments. It differs from Spondylopecten erinaceus (Buv.) (1852, p. 23, pl. 19, figs. 7-12) in having smaller number of ribs (20 as opposed to 22-24) and in the absence of protuberances on the ribs. From Spondylopecten badiensis (Cox) (1952, p. 16, pl. 1, fig.14) it differs in having smaller number of ribs (20 as opposed to 23-24). Range and age. USSR: M. Kavkaz {Caucasus} (Azerbaijan). Callovian. Outside of the USSR: lower Callovian of India.» KASUM-ZADE, A. A. & L. F. ROMANOV.
