Abstract
THE rocks under contlideratiou in this paper, are those lying above the yellow Ohouteau limestone in the region in question.They consist of beds of gray Ii mestone, more or less crystalline in the various strata, with scattered bands of lenticular chert concretions.No results of careful stratigraphical work, based on palooontological evidence, have ever .beenpublished in connection with this region, and though the rocks have been correctly considered as equivalent to that part of the Mississippian Series known in Illinois and Iowa as the Burlington and Keokuk Groups, the subdivisions of the strata have never been properly pointed out.The object of the present paper is to dissect out the val'ious sub-faunas, to note their order of succession and the relations which they hold to each other.During the summers of 1892 and 1893 the writer made quite extensive collections of the fossils from the quarries and other exposures in and about Springtield.From the study of these collections, the whole series of strata has been divided into twelve zones, which can be distinguished by their faunas.
