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 Bythograeidae Williams, 1980 Segonzacia mesatlantica (Williams, 1988) ( Fig. 16 A, B) and Austinograea alayseae Guinot, 1989 ( Fig. 16 C– F) 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.
