Upper Ordovician bryozoa from Dalmanitina beds of Borenshult, Östergötland, Sweden

Bryozoan fauna from samples collected in 1823 during construction of Göta Channel in exposures no more accessible since that time comprises 14 idemified species belonging to 11 genera. One genus, Radiotrypa, and 13 species are established herein. Fauna differs in composition from other contemporary faunas in Balto-Skandia, probably because of differences in ecological conditions.
