Ossicles I and II are inclined about 45° in the antero ventral direction. The unpaired propyloric ossicle (VI) is inclined 45° in the posterior direction; its dorsal margin is straight and dorsally rounded. The pectinal ossicle (VIII) is ring-shaped with eight accessory teeth. An anterior directed spine extends from the middle of the subdentate ossicle (XIV). The postpectinal ossicle (X) is at the posterior end circular rolled about 320°. Ossicles “XVII–XXIII” and “XXI–XXIb” are observed as mixed ossicles. It has a remarkable median narrowed strip. Ossicle XVIII has a comparatively greatly increased surface. Ossicle XXVIa is not recognisable.
