 Kosmoclymenia sp. aff. K. bisulcata (Münster, 1832) from the D. trigonica and the late P. jugosus Zones at Dzikowiec in the Sudetes. Diagnoza Conch of generalized morphology developing ventrolateral furrows at diameter of about 40 mm or later, ornamented with dense distinct growth lines. Porównanie The species is similar to K. bisulcata in general conch form but differs in underived shape of mature aperture and the lack of lateral furrows; probably also in distinctness of growth lines, a feature dependant on preservation. K. adammeri Korn et Price, 1987 is even more similar to the Dzikowiec form than that species in low whorl expansion rate, but its diagnostic character is a longitudinal striation. Such a striation sometimes developed in the Dzikowiec Kosmoclymenia, but rather on specimens of juvenile morphology resembling K. undulata. Autekologia Występowanie geograficzne Dzikowiec.
