RELATIVE AGES OF THE LOWER KANAWHA GROUP AND THE ALLEGHENY 



SERIES. 



In the preceding list the asterisk (*) marks species which appear to be 

 identical in form with material examined from the Allegheny series. 

 It should, however, be noted that while these species, which constitute 

 but a small percentage in the ferns, occur also in the Allegheny series, 

 they do not include forms that are characteristic of that series. On the 

 contrary, they comprise species which are either of wide range or which 

 in most cases originate in the upper zone of the Pottsville formation. 

 Referring again to the list, the species distinguished by the dagger (f) 

 are either identical with or they are modifications of Upper Pottsville 

 forms. The much greater percentage of species in the latter category 

 falls far short of indicating the really very intimate connection of the 

 floras of the lower group of the Kanawha series with those of the Potts- 

 ville formation, both in West Virginia and in the type district. 



An examination of the combined floras from the lower half of the 

 Kanawha series reveals at once the absence of both the characteristic 



* Identical with species in the Allegheny series. 



t Identical with or modification of Upper Pottsville forms.
