Scardinius erythrophthalmus ( Linnaeus, 1758)

Fig. 19 .

Material and dimensions.—See Table 2.

Description.—The general shape is trapezoid in the posterior portion and semicircular in the anterior portion. The four edges are well developed. The medial and lateral margins of the smaller lapillus ( Fig. 19C ) run straight and regularly. In contrast, those margins curve irregularly in the larger lapilli ( Fig. 19A, B ). The posterior margin reveals a distinct concavity in all specimens. The concavity is situated in the mid of the posterior margin in the smaller lapillus, but close to the posteromedial edge in the larger lapilli.
