Lithostratigraphy and biostratigraphy of the Lower Carboniferous of the Nizký
   Jeseník Hills is being revised.  There increases the number of faunal finds which enable
   the biostratigraphical correlation of very thick and relatively monotonous Culm series.
   This makes possible to put the lithostratographical division of the Culm series and the
   research of facies on a biostratigraphical basis.
        The present author has revised the collections of previous authors, deposited
   in the collections of the Ostrava Mining University (the collections of  K. P a t t e i s k y),
   in the Ostrava Museum (the collections of V. S u s t a), in the Silesian Museum of
   Opava (mostly the collections of L. Knopp), in the Olomouc Museum (the col-
   lections of various authors) and in the National Museum of Prague (mostly the col-
   lections of  P. A 1 t a r) and carried out extensive new collections, on the already known
   localities and on new localities as well. Many new collections on new localities were
   collected by mapping geologists J. Dvorak and L. Mastera.  At the same time,
   the author carried out the lithostratigraphical research of the Culm series in the
   central and northern part of the Nizký Jeseník Hills and constructed geological
   sections through these series.  The result is the lithostratigraphical division o t e
   Moravice Group in the central and northern part of Nizký Jeseník, verified by faunal
   research, and the subdivision of the Horní  Benesov Group as well.
