Dr. Bartenstein's results show considerable progress in the recognition of marine horizons within the belt of Westphalian strata lying between the Sarnsbank Coal Gastrioceras subcrenatum Marine Band and the Katharina Anthracoceras vanderbeckei Marine Band. Kukuk (1938, pp. 166–171) recognized in this stratal belt but twelve marine or Lingula horizons, whereas the author from his foraminiferal finds in the same strata adds evidence of six more marine incursions in Westphalia.
