DiCTYOPTEEIS, Gutb. 



DiCTYOPTEEis oBLiuuA, Bunbury. 

 M. C, Sydney {B, Brown). 



LoNCHOPTEEis, Brongn. 

 Lois-CHOPTEEis TENUIS, spoc. nov. PI. XIII. fig. 103. 



Pinnate or bipinnate ; pinnules contiguous at the base, nearly at 

 right angles to petiole, oblong elongate, obtuse. Network of veins 

 very delicate. Allied to L. Bricii, Brongn., but with smaller, more 

 elongate pinnules and finer veins. I suspect this to be a thick-leaved 

 Pecopteris, showing a coarse cellular reticulation on the upper surface. 



M. C, Sydney {B. Brown). 



Sphenopteeis, Brongn. 



1. Sphenopteeis munda, spec. nov. PI. XIII. fig. 97. 



Like S. Dubuissonii, Brongn., or S. irregularis, Sternberg, in habit ; 

 but the pinnules are obovate, decurrent, and few-veined. 

 M. C, Grand Lake ((7. F. HaHt). 



2. S. HYMENOPHTLLOIDES, BrOUgU. 



M. C, Sydney (B. Brotvn) ; IJ. C, Joggins (J. W. D.). 



3. S. latioe, spec. nov. PL XIII. fig. 98. 



Petiole forking at an obtuse angle, slender, tortuous ; divisions 

 bipinnate ; pinnae with broad, rounded, confluent pinnules ; veins 

 twice forked, with sori in the forks of the veins. In habit like S. 

 latifoUa, Brongn., S. Newherryi, and S. squamosa, Lesq. 



M. C, Grand Lake {C. F. Hartt) ; U. C, Pictou (J. W. D.). 



4. S. DEciPiENS, Lesquereux. 

 M. C, Sydney {B. Brown). 



5. S. GEAciLis, Brongn. 



M. C, Joggins (J. W. D.) ; Grand Lake (C. F. Hartt). 



6. S. aetemisijefolia, Brongn. 



M. C, Grand Lake {C. F. Hartt) ; Sydney {B. Brown). 



7. S. Canadensis, spec. nov. PI. XIII. fig. 99. 



General aspect like ^. Hoeninghausi, but secondary pinnules with 

 a margined petiole, and oblong pinnules divided into three to five 

 obtuse points. It is not unlike B. marginata, from the Devonian of 

 St. John. 



Bay de Chaleur (Logan) ; Sydney ? (B. Broivn).
