484 THE CARBONIFEROUS SYSTEM. 



Phyllopteris, Brongn. 

 Phyllopteris antiqiia, spec. nov. (Fig. 166, E). Pinnate; petiole 

 thick, woody ; pinnules oblong, pointed, attached by the middle of the 

 base ; midrib strong, extending to the point, giving off very oblique 

 nerves, which have obliquely pinnate nervules not anastomosing. A 

 remarkable frond, which, if not the type of a new genus, must belong 

 to that above named. M. C, Sydney (R. Brown). 



Alethopteris, Sternberg. 



1. Alethopteris lonchitica, Sternberg. (Fig. 166, C). M. and U. 

 C, Joggins (J. W. D.) ; M. C, Sydney (R. Brown) ; Grand Lake 

 (C. F. Hartt). Very abundant throughout the Middle and Upper 

 Coal formations, and so variable that several species might easily 

 be founded on detached specimens. 



2. A. heterophylla, L. and 11. (Fig. 156, A). L. C, Parrsborough 

 (A. Gesner). 



3. A. Grandini^ Brongn. M. C, Sydney (R. Brown). 



4. A. nervosa^ Brongn. M. C, Sydney (R. Brown) ; Bay de 

 Chaleur (Logan) ; U. C, Pictou (J. W. D.). 



5. A. murlcata, Brongn. M. C, Joggins, Bathurst (Lyell) ; U. C, 

 Pictou (J. W. D.). 



6. A. pteroides, Brongn. [A. Brongnariii, Goeppert). L. or M. C, 

 Bathurst (Lyell's list). 



7. A. Serlii, Brongn. M. C, Sydney (R. Brown) ; Bay de Chaleur 

 (Logan) ; Springhill (C. F. Hartt). 



8. A. grandis, spec. nov. (Fig. 72). Bipinnate ; pinnae broad, 

 contiguous, united at the base ; veins numerous, once forked, not 

 quite at right angles to the midrib. Upper pinnje having the pinnules 

 confluent so as to give crenate edges. Still higher the apex of the 

 frond shows distant dccurrent long pinnules Avith waved margins. A 

 very large and fine species of the type of A. Ser^lii and A. Grandini, 

 but much larger and different in details. Its texture seems to have 

 been membranaceous ; and fragments from that part of the frond 

 where the long simple pinnules are passing into the compound ones 

 might be mistaken for an Odontopteris. Bay de Chaleur (Logan). 



Pecopteris, Brongn. 

 1. Pecopteris arborescens, Schloth. Seems to have been an her- 

 baceous species with a very strong petiole. It occurs in an erect 

 position in a sandstone on Wallace River. M. C, Sydney (R. 

 Brown) ; U. C, Pictou (J. W. D.) ; Wallace River (Dr Creed).
