In the paper the author gives some more data on the shell SEM structures in Marstoniopsis scholtzi (A. Schmidt, 1856), not described by him earlier. He gives descriptions of the shell outer surface and sections perpendicular to the growth lines. Based on these data and the ones published in his monograph (Falniowski, 1990, this volume), the paper is to present some idea of what possible relationships of Marstoniopsis are.
