point whether the Arta beds should be regarded as a separate 

 division or included with the Permian, and it matters little for 

 purposes of correlation whether an American writer follows one 

 group of authorities rather than the other. Personally, I am quite 

 willing to include them both in a single division of the time scale, 

 and although believing that propriety would be better served by 

 retaining Permian for only the upper division, I am willing to extend 

 that term to cover the entire series because of the usage which it 

 has received in this sense, but I am not willing, for reasons which 

 must be obvious, to call the whole Permian and the upper part 

 also Permian, and for the sake of precision I have been temporarily 

 calling the upper beds Permian, the lower beds " Permo-Carbon- 

 iferous," and the whole "Permo-Carboniferous" and Permian. If, 

 in my Guadalupian report and elsewhere, I restricted the term 

 Permian to the supra-Artinskian beds, it was done as a matter 

 of procedure in nomenclature. I had no opinion of my own as to 

 the classification of the beds to express or defend, although, if I 

 had, excellent authority could be named in support of my position. 



DISCUSSION BY DAVID WHITE 



The plant material collected by myself from the breaks of the 

 Little Wichita River near Fulda, Tex., is derived from two near-by 

 localities, both near the middle of the Wichita formation. The 

 fossil plants previously listed by Fontaine and White from two 

 other localities, and recorded 1 by them as Permian, appear to repre- 

 sent a mixed flora, one of the localities being under suspicion of 

 Pennsylvanian age. Neither of the latter two localities was visited 

 by me on account of the lack of time; but on the basis of informa- 

 tion received, I am disposed to believe that the stratigraphically 

 lower beds at Antelope are probably Pennsylvanian. 



The identifications given on p. 122 are provisional. Later it is 

 hoped, when the material will have been increased both geographi- 

 cally and stratigraphically, a formal report covering the floras of 

 the "Red Beds" will be prepared. The species printed bold-face 

 in the lists on p. 122 are characteristic of the Permian. They 

 point somewhat distinctly to the Rothliegende age of the beds.
