Neuropteris rarinervis Bunb. 



Quart. Journ. Geol. Soc. Vol. III. 1847, p. 425, PI. xxii. 



Gape Breton, Nova Scotia. Goal-Measures. 



Bunbury's figure represents a portion of a frond with a length 

 of 32 cm. The pinnules and venation are clearly preserved. 

 Solms-Laubach ^ refers to this species as an example of a fern 

 possessing Aphlebice. Lesquereux ^ has figured several examples 

 of N. rarinervis from Illinois, some of which show cyclopteroid 

 aphlebia — leaflets ; and more recently Zeiller ^ has figured an 

 aphlebia-bearing specimen from the Valenciennes Coal-Measures. 

 In Bunbury's example we have no actual proof of the occurrence 

 of such cyclopteroid leaflets. This species has been recorded from 

 several English localities, and Zeiller * has lately recognised it 

 among the fragments of Coal-Measure plants from the Dover 

 boring. 



Odontopteris subcuneata Bunb. 



Quart. Journ. Geol. Soc. Vol. iii. 1847, p. 427, PI. xxiii. fig. 1. 



Gape Breton, Nova Scotia. Goal-Measures. 



In the first notice of this fragment it is described as probably 

 the extremity of a frond, and compared to Odontopteris ohtusa 

 Brong. Schimper ^ recognises the species in his Traite de pale'on- 

 tologie vegetale, but Bunbury ®, in a later paper, prefers to consider 

 it as a terminal portion of some large Neuropteris ; " at any rate," 

 he adds with his usual caution, " a species ought not to be founded 

 on so imperfect a fragment as the only one I have seen of this 

 supposed Odontopteris." In his Studien uber Odontopteriden, Weiss'' 

 includes Odontopteris Subcuneata in his subgenus Xenopteris. 

 Lesquereux ^ retains Bunbury's species, and speaks of it as possess- 

 ing well-marked distinctive characters. It would seem then that 

 we are justified in accepting this terminal fragment as the type of 

 a distinct species. 



Pecopteris taeniopteroides Bunb. 



Quart. Journ. Geol. Soc. Vol. III. 1847, p. 428, PI. xxiii. fig. 2. 



Gape Breton, Nova Scotia. Goal-Measures. 

 The small specimen accurately represented in Bunbury's figure 

 possesses a very well-defined venation. It is much too small to
