• Resumen

  • In Berriasian-inferior Valanginian strata of southeastern France, the genus Protocythere Triebel, 1938, is well represented (at least 15 species), and, from biostratigraphical point of view, of a great interest. Most of the species are already known, but four of them are new. These are described here. Their stratigraphic range has been ascertained by comparison with Ammonites and Calpionelles. One is left in open nomenclature because of a lack of sufficient material. In addition, a «forme costata» is considered as a variation of species P. camberiensis Donze, 1964.
