The few late Lower Carboniferous (lower Pendleian) trilobite remains from Magdeburg (Sachsen-
 Anhalt, Germany) described by WOLTERSTORFF (1899) are revised.  These and additional somewhat
 richer collections of trilobitcs from the Flechtingen Block (Magdeburg and Hundisburg regions),
 made during 1971-2001 from six horizons within the Magdeburg-Flechtingen Formation, a more
 than 1000 m thick flysch sequence of Culm facies type, include the following taxa: Paladin (Paladin)
 pitzi HAHN & HAHN, 1968, Paladin (Paladin) magdeburgensis n. sp., Paladin (Paladin)flechtingianus
 n. sp., Kulmiella wolterstorffi n. sp., Kulmiella olvetalensis n. sp., and Cyrtoproetus (Cyrtoproetus)
 sp. indet.  The six species occur in the Cravenoceras leion Zone (E 1 a, including the Emstites schaelkensis
 fauna) within a sequence of four ammonoid levels characterized by Edmooroceras tornquisti,
 Cousteauceras? involutum, Edmooroceras bisati, Edmooroceras medusa; some are already known
 from the latest Upper Viséan (Brigantian).  The presence of Kulmiella and Cyrtoproetus within the
 basal Serpukhovian at Magdeburg shows that the change of the trilobite succession at the traditional
 Viséan-Namurian boundary is less distinct than two remarkable earlier changes within the Upper
 Viséan (Asbian-Brigantian boundary and mid-Brigantian level).
