Abstract
This study originated in the attempt to identify a number of Rhynchotremas and Zygospiras from the Plattin and Decorah formations of Ste. Genevieve County, Mo. Comparisons were made with sets from several other localities in the Mississippi valley, and thus considerable additional material was examined, involving not only Black River horizons, but the Kimmswick and Maquoketa as well.
