39,275. PI. XIII. Fig. 1. 



Part of a large pinna, with pinnules longer and more tapering

 always contiguous basally, where they are attached to the axis 

 of the pinna. Sori indistinct.

V. 3666. A clearly preserved impression in ironstone of large 

 pinnules which vary in breadth, the fertile segments being narrower 

 than the sterile. 



Gristhorpe. 



10,333. Imperfect fertile pinnules, in some of which the- 

 margin is slightly undulate, but this character is by no means 

 constant, and is in part due to inequalities on the surface of 

 the rock. 



Upper Shale, Gristhorpe. Mantell Coll. 



10,371. Large sterile segments, 4'5 cm. long and 6 mm. broad, 

 showing very distinct venation. 



Upper Sandstone, Scarborough. Mantell ColL 



39,243. A fairly large example of fertile pinnules, about 4 cm. 

 in length and 4 mm. broad ; individual sporangia may be recognized 

 on some of the segments. 



Upper Shale, Scarborough. Bean Coll.
