Recent developments on the morphology of the brachyuran foregut ossicles and gastric teeth Author Brösing, Andreas text Zootaxa 2010 2510 1 44 journal article 10.5281/zenodo.294144 ce99f918-054b-4464-a0eb-b176579eb998 1175-5326 294144 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).

The pyloric ossicle (III) is paired. Ossicles	“XVII–XXIII”	occur	as	a	mixed	ossicle.	A	lateral	mesopyloric
ossicle (XIXa) is recognisable.

Leucosia anatum Herbst, 1783 The urocardiac ossicle (VII) has a convex bulge antero dorsally. FIGURE 11.
