8. Pecopteris pteroides? (Brongu. p. 329, t. 99. f. 1?) 



Two large specimens seem to approach near to this species. The 

 leaflets are rather narrower and less closely set than in Brongniart's 

 figures ; the venation very indistinct ; and the basal leaflets of the 

 pinnse are not sufficiently well preserved to determine the species with 

 certainty. 



9. Pecopteris ? 



This seems more nearly allied to P. Plukenetii (Brongn. t. 107. 

 f. 2) than to any other described species ; but the lobes of the leaflets 

 are of a much rounder form than in that plant ; the leaflets them- 

 selves larger and more obtuse, except those towards the extremity of 

 each pinna, which become successively more and more acute ; and 

 the pinnse are broader and more ovate in their outline ; venation very 

 obscure. Another specimen, which I conjecture to belong to the 

 same plant, and which is perhaps one of the lowest and largest pinnse 

 of the frond, is pinnated, with broad ovate leaflets, divided half way 

 down into rounded lobes. The venation in this specimen is well 

 preserved ; the midrib of each leaflet is pinnated with rather strong 

 lateral veins running into the several lobes, but not reaching to the 

 extremities of them, and these veins are again pinnated with slender 

 and sometimes forked veinlets. 



10. Calamites approximatus (Brongn. Veg. Foss. p. 133, t. 24). 



A very large specimen, decorticated, but well characterized. 



Calam. approximatus has been found in the coal-mines of Alais, in 

 the department of the Gard, of Liege, of St. Etienne, of Kilkenny ; 

 in several of the English coal-fields, and abundantly in those of Nova 

 Scotia and Cape Breton. 



11. Calamites SUCKOWII? 



Many fragments, but none sufficient for the satisfactory determi- 

 nation of the species. 



12. Asterophyllites ? 



A species with short internodes and very narrow incurved leaves 

 many in a whorl, much longer than the internodes. 



13. Annularia longifolia. 



{Asterophyllites equisetiformis, Lindl. and Hutt. Foss.Fl.v.ii.t. 124.) 



Certainly the plant of the 'Fossil Flora,' and the same as No. 40 

 of my paper on the coal-plants of Cape Breton. 



Found in the Newcastle coal-field, at Wettin near Halle, and in 

 the island of Cape Breton. 



14. Annularia ? 



A small species, with short, wedge-shaped, very obtuse leaves ; I 

 think the same as No. 41 of my paper above-quoted.
