The genus Ptychophylloceras from the Berriasian of the Crimea is revised. P. ptychoiciun (Querist.) is considered as a junior synonym off! seinistilcattim (d'Orb.). The suturai ontogeny and inner structure are studied. Three species, i.e., P. semisulcatum (d'Orb.), P. inordinatiun (Toucas), and a new species, P. teniticostatum, are described.
