5. Cordaites angustifolms, Dawson (possibly young- leaves of C, 

 ■ Robbil, Dawson).* 



6. Cordaites Robbit, Dawson.* 



7. Anmdaria laiifolia, (Dawson)* Kidston. 



8. Anmdaria acicularis, (Dawson)* Sp. (Under this species I 



note that Dr. White employs the term "Lancaster formation" 

 suggested for the strata described as " Middle Devonian" 

 from the " fern ledges" of Lancaster, New Brunswick.) 



9. Aster ophyllites parvidus, Dawson.* 



10. Netiropteris Pocahontas^ var. inceqiialis, n. var. Allied to 



Cardiopteris Eriana^ Dawson,* and Odontopteris squamosa, 

 Dawson, which, bye the bye, has been called O. Dawsoniana 

 by S. A. Miller. Dr. White adds that it deserves a special 

 comparison with the Neuropteris Pocahontas group of Potts- 

 ville form's. 



11. Megalopteris plumosa, D. White, n. sp. This species closely 

 resembles M. Dawsoni, Hartt, from the so-called Middle 

 Devonian of New Brunswick. 



12. Alethopteris discrepans, Dawson.* This species, originally de- 

 scribed from the "fern ledges" of New Brunswick occurs in the 

 Pottsville formation at the New Lincoln Mine. Of specimens 

 from this place, Dr. White says : they " appear to agree in all' 

 respects with specimens from the 'fern ledges' at St. John." 

 "The occurrence of this species," he adds, "together with 

 Sphenopteris Harttii, S. pilosa and Pecopteris serrulata, Hartt, 

 in the Upper Lykens division of the Pottsville formation points 

 strongly to the close relationship between the flora of the 

 latter and that of the supposed Middle Devonian beds at St. 

 John, a relationship so close as to convince me that no appre-j 

 ciable diff"erence in age exists between the plant beds at the! 

 two localities." (p. 886.) ' 



13. Pecopteris serrulata, Hartt. 



14. Sphenopteris pilosa, Dawson.* 



15. Spheyiopteris Harttiiy Dawson,*
