Ossicles I and II are inclined about 45° in the antero-ventral direction. The zygocardiac ossicle (V) has a semicircular impression antero ventral. The unpaired propyloric ossicle (VI) is nearly vertical. The pectinal ossicle (VIII) is horseshoe-shaped with eight accessory teeth. The inferior lateral cardiac ossicle (XIII) has a connection-pice to the subdentate ossicle (XIV) antero dorsal. Ossicles “XVII–XXIII” are observed as a mixed ossicle. Ossicle XXII is not recognisable.
