Material.— Four specimens from set K, ZPAL Bp 57/21–22, 37, 53 .
Description.—Exterior: see Biernat and Racki (1986a) and Sartenaer (1998b).
Ventral interior ( Fig. 4 View Fig ) with slightly thickened umbo and deeply ruffled inner surface of the muscle scars suggesting attachments of the ventral adjustors; teeth strong, stout, but short; dental plates absent, but low flanges may be interpreted as rudiments of these plates (see Fig. 4 View Fig , distance 0.9–1.5). Dorsal interior with short, divided hinge plates which are distinctly inclined medially to the floor of the valve; crural bases distinct, thickened; crura slightly divergent, proximally crescent− to boomerang−shaped in cross section, distally calceolate and ventrally curved ( Fig. 4 View Fig , distance 1.6–2.4).
Remarks.— Biernat and Racki (1986a) illustrated the internal structures of the newly described species only on photographic plates which are quite illegible, wherefore their original specimens have been redrawn using a camera lucida and redescribed by the present authors.
Stratigraphic and geographic distribution.—This species is known solely from the middle Famennian of the Kowala section.
