UPPER PALEOZOIC FORMATIONS OF KANSAS 725 



the beds composing the division must be referred to the Wichita 

 division of the Permian. Since the Wichita division is now 

 made to include the area heretofore referred to as the Albany 

 division, it becomes at once the most important and interesting 

 part of the Permian in North America." 1 And he concluded 

 with the statement that " it has been determined that the Albany 

 division, with its numerous fossils, is but another facies of the 

 Wichita division which is beyond question Permian." 2 



If Professor Cummins be correct in correlating the Fort 

 Riley limestone with the top of the Wichita division of Texas it 

 very decidedly supports the reference of the Upper Paleozoic 

 formations of Kansas to the Permian. He had stated that all 

 the typical localities of invertebrate fossils described by Dr. C. 

 A. White were included in the Wichita division, " the greatest 

 number of vertebrate fossils described by Professor Cope " and 

 the fossil flora described by Dr. I. C. White; 3 while the Phaco- 

 ceras Dumblei "was taken from the very top of the Albany 

 division." 4 



The fossil named and described by Professor Heilprin as 

 Ammonites Parkeri which was reported from rocks of Carbonifer- 

 ous age in Wise county, northern Texas, 5 was referred to Popano- 

 ceras by Professor James P. Smith 6 who stated, on the authority 

 of Professor Cummins, that the Popanoceras Parkeri beds are in the 

 Strawn [Richland] division and therefore of the age of the Lower 

 Coal-measures. 7 The occurrence of this type in the Texas beds, 

 however, led Karpinsky in 1889 to write as follows: Since the 

 Popanoceratidae up to the present time have not been found in 

 other countries in deposits which are older than the Permo- 

 Carboniferous (in which the commonest Ammonites occur) ,
