 This species closely agrees with the European forms figured and described 

 by Zeiller. The fine, longitudinal wrinkles on the ridges separating the 

 bolsters are however not figured as appearing on the European forms. The 

 bolsters are a little wider than those figured by Lesquereux from Pennsyl- 

 vania.^ 



Locality : Lower Block Coal east of BoAvling Green, Asherville and north 

 of the Roadman school. A form doul)tfully referred to this species was 

 also found in the Yoho School locality. 



Genus Siyillaria Sternburg 



Sigillaria elegansf Sternburg 



PI. VII, Fig. 8; PI. VIII, Fig. 7. 



The extremely poor state of preser.vation of these plants makes their de- 

 termination uncertain. The form shown in pi. VII, fig. 8, appears to possess 

 some of the chai'acteristics of S. lassellala. The uinisual length of the parich- 

 nos in the form shown in pi. VIII, fig. 7, may be due to the conditions of fossil- 

 ization. 



Localities: The species figured in pi. VIII, fig. 7, is from the Roadman 

 school; the form shown in pl. VII, fig. 8, is from Bowling Green.
