The genus Kozlowskia from the Couvinian of Grzegorzowice in the Holy Cross Mountains (Góry Świętokrzyskie), assigneil to a new family Kozlowskiidae, was erected by the writer in 1958. Now, on the basis of a new material, supplementary observations have been made concerning the structure of wall and ontogenetic development. At the same time, since the name of Kozlowskia was preoccupied (Fredericks, 1933), new generic and family names have been introduced.
