perhaps might belong to Pecopteris oreopteridia, but its state of preservation did not 

 admit of a satisfactory determination. Further collecting may reveal the existence of 

 these species in the Upper Pennant Series, but in any case they are rare.

Analysis of Table II. 



The plants from the Lower Pennant Series contain a very remarkable admixture 

 of Upper and Middle Coal Measure species. 



Leaving out a doubtful record for this series, — Calamitina Gopperti, Ett., sp., of 

 whose horizon there is some uncertainty, — of the 36 species from these rocks, 22 occur
