Calappidae de Haan, 1833

Calappa granulata (Linnaeus, 1758) ( Fig. 7 )

The pyloric ossicle (III) is paired. The zygocardiac ossicle (V) has a semicircular impression antero ventral. The propyloric ossicle (VI) is nearly vertical, and its dorsal margin is U-shaped and has a sharp margin. The pectinal ossicle (VIII) is horseshoe-shaped with three accessory teeth. The inferior lateral cardiac ossicle (XIII) has a clearly antero lateral connection to the subdentate ossicle (XIV). On the subdentate ossicle (XIV) there is a circular ventral impression.
