Abstract

Seven new species of articulate brachiopods from the Burlington Limestone of northeastern Missouri are described. Caenanoplia burlingtonensis, n.sp., and Magnumbonella macrura, n.sp., are type species for new genera. Other new species are Leptagonia missouriensis, Marginatia magna, Unispirifer? corpulentus, Punctospirifer acutus, and Composita pikensis. Most of the specimens occur in the lower Burlington 'white chert' and are part of the R. R. Rowley Collection from Louisiana, Pike County, Mo. The brachiopod fauna of these beds appears to be an age equivalent of that of the earliest Osagian Fern Glen Formation.
