This paper is an elaboration of the representatives of the Upper Visean tetracoral families Amygdalophyllidae Grabau and Rozkowskiidae n. fam. of the Holy Cross Mts. Development trends within the superfamily Aulophyllicae, as well as the microstructure of septa and columellae are presented in the general part, in which the microstructure of columella has been assumed as a basis for erecting families. The systematic part contains descriptions of 16 species (and two subspecies) belonging to four genera and two families. Most taxonomic units have for the first time been erected in the present paper.
