ANTHRACOLITHIC ROCKS OF KANSAS

composed of the Artinsk (CPg) and the superjacent dolomitic lime- 

 stones (CPc). 



Hans V. Staff has recently published the following table of the 

 Russian Upper Carboniferous Fw^w/ma-bearing horizons:^ 



Dr. Girty criticizes the statements which I have made concerning 

 certain fossils; but as the invertebrate fauna, exclusive of the insects, 

 is being critically examined by Dr. J. W. Beede who has studied it 

 more thoroughly than anyone else, I will not devote any particular 

 space at present to the consideration of this part of the subject, with 

 the exception of calling attention to some facts which support my 

 identification of the Kansas specimens as Fusulina. 



Dr. Girty has written as follows: 



It might also be pointed out that just below the Artinsk a zone in the Russian 

 section is characterized by a profusion of Schwagerina occurring in association 

 with Fusulinas. Now Schwagerina has never been reported from the Mississippi 

 Valley, while I have recently^ offered reason for believing that the Fusulinas of the 

 Kansas section, if they do not belong to a different genus, at least show important 

 differences from the typical Fusulinas. These facts seem to destroy Mr. Prosser's 

 argument so far as this item of evidence is concerned. At the same time these very 

 forms furnish more stable evidence looking somewhat in the same direction.^
