Leucosiidae Samouelle, 1819

Philyra variegata (Rüpell, 1830) ( Fig. 12 ) and Philyra laevis (Bell, 1855) Ossicles “IV–V” is observed as a mixed ossicle. The zygocardiac ossicle (V) has a semicircular impression antero ventral. The pectinal ossicle (VIII) is conical and has one accessory tooth. The ossicles (XI and XIXa) are not recognisable. The inferior lateral cardiac ossicle (XIII) has a clear antero lateral connection with the subdentate ossicle (XIV).

Leucosia anatum Herbst, 1783

The urocardiac ossicle (VII) has a convex bulge antero dorsally.
