INTRODUCTION. 



In 1895 trie writer published a paper on "The Classification 

 of the Upper Paleozoic Rocks of Central Kansas" in the Jour- 

 nal of Geology. 1 Additional field work and study of the Cot- 

 tonwood Falls quadrangle render it advisable, in compliance 

 with the custom of the United States Geological Survey to 

 designate each lithologic individual capable of representation on 

 the topographic map as a formation, to subdivide three of the 

 units which were described as formations in that article. 



A few changes in classification or nomenclature have been 

 made which are also explained in this paper. Dr. J. W. Beede,
