Tinca tinca ( Linnaeus, 1758)

Fig. 20 .

Material and dimensions.—See Table 2.

Description.—The general shape is elongate−rhombic. The anteromedial edge is the most prominent edge, even in small specimens ( Fig. 20B, D, E ), whereas the posteromedial edge is absent or very small. The posterolateral edge is distinct and forms the posterior tip of the lapillus, also the anterolateral edge is well developed. The lapillus illustrated in Fig. 20A shows a prominent cut in the middle of the medial margin and strongly crenulated rims.
