Fenestella remota Foerste

Coal Measures: Flint Ridge and Bald Hill, Ohio. 

 1887 Fenestella remota. Foerste, Bull. Den. Univ., Vol. 2, p. 87, PI. 7, Fig. 5. 



Foerste's description. "Four cells to each fenestrule, a compara- 

 tively broad median keel occupied by a closely arranged series of 

 nodes. The reverse is occupied by distinct longitudinal striae/' The 

 species closely resembles F. limbata, but is distinguished by the greater 

 distance between the dissepiments and by the greater number of pores 

 opposite each fenestrule.

Lower Coal Measures: Ohio. 



Remarks. A very small, delicate species of Fenestella is common 

 in the marine limestones of the Pottsville formation which has been 

 referred with some doubt to Fenestella shumardi, a form originally de- 

 scribed from a far distant locality. However, this form agrees very 

 closely with Meek's interpretation of Prout's species, which is also 

 reported by him to be present in the Lower Coal Measures of Ohio. 

 If Meek's form is really identical with F. shumardi there seems little 

 doubt that the Ohio specimens likewise belong to that species.
