039E87F8D47BB10DFF4A345AB1F27C96.taxon	discussion	Discussion. Skryjelites gen. nov. is a monotypic genus which resembles the Mediterranean Ordovician genus Elegantilites Marek, 1967 regarding the sculpture of the dorsal side. However, the clavicles in all known species of Elegantilites show fully opened and nearly diverging bilobate cardinal processes of hook-like cross-section. Nevertheless, it is possible, that Skryjelites gen. nov. represents one of parent morphological types of Elegantilites. Occurrence. Middle Cambrian, Skryje – Týřovice Basin, Bohemia.	en	Valent, Martin, Fatka, Oldřich, Szabad, Michal, Micka, Václav, Marek, Ladislav (2015): Skryjelites auritus gen. et sp. nov. and Quasimolites quasimodo gen. et sp. nov. — two new middle Cambrian hyolithids (?

W / h index = 1.3, angle of divergence ranging between 15 and 20 degrees. Amblygonal aperture; semicircular ligula provided with one transversally elongated apertural muscle scar.

Surface sculpture of conch consisting of very fine, almost indistinct growth-lines. Platyclaviculate operculum flat and robust clavicles divided by longitudinal diaphragms in hollow channels. In crosssection triangular cardinal processes opened and broadly diverging. Their anterior and posterior ends almost parallel; their axes lying in one line. Very thick-walled cardinal area sagitally elongated into rounded processes. Several radial channels developed between the outer and inner surfaces of cardinal shield. These channels most probably made the cardinal shield lighter. Distinct paired adductor muscle scars arched and deflected. Sculpture of external opercular surface consists of growth-lines. Several thicker riblets developed near summit of operculum. Dimensions. Maximum length of adult specimen was 25 mm. Occurrence.
