Cyclostomatous Bryozoa from the Kullsberg Limestone

The bedded limestones associated with the “reef” limestones in the Siljan district of Sweden contain numerous bryozoa. Samples from the quarry at Kullsberg near Rättvik have been investigated with respect to their content of bryozoa. The material is Late Caradocian in age. The main part of the fauna consists of trepostomes and cryptostomes, but cyclostomatous bryozoa also occur in small numbers. Three species belonging to the order Cyclostomata are identified in the investigated material, one of them new to science. The identified species are Kukersella boreale (Bassler), Corynotrypa schucherti Bassler and Mitoclemella kullsbergiana n. sp.
