Phyllopteris, Brongn. 

 Phtllopteeis antiqtta, spec. nov. PI. XIII. fig. 96 



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.

Alethopteris, Sternberg. 



1. Alethopteris lonchitica, Sternberg. 



M. and V. C, Joggins {J. W.D.); M. C, Sydney {E. Brown); Grand 

 Lake (C. F. Hartt). 



Yery abundant throughout the Middle and Upper Coal-formations, 

 and so variable that several species might easily be founded on 

 detached specimens.

8. A. GRANDis, spec. nov. PI. XIII. fig. 100. 



Bipinnate ; pinnae broad, contiguous, united at the base ; veins 

 numerous, once forked, not quite at right angles to the midrib. 

 Upper pinnae having the pinnules confluent so as to give crenate 

 edges. Still higher the apex of the frond shows distant decurrent 

 long pinnules with waved margins. A very large and fine species of 

 the type of A. Serlii 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 

 Oclontopteris.

Pecopterts, Brongn. 

 1. Pecopterts arborescens, Schloth. 



Seems to have been an herbaceous species with a very strong
