\Q&.— Sphenopteris repanda, L. et H. Type SPECIMEN, F. F., pi. 84. 

 Small frond or a pinna, very indistinctly preserved and diffi- 

 cult to define. Nerves much branched and spreading. It has 

 not the character or appearance of a Sphenopteris. The lower 

 part of the frond separate. The figure, pi. 84, very inaccurate 

 and misleading. 



Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 166, 

 161). 



Remarks, — The Type specimen of Sphen. repanda, L. et H., 

 F. F., pi. 84, is a very imperfect impression of a primary pinna 

 of some large fern. The Hutton drawing is very incorrect, and 

 gives quite an erroneous idea of the shape of the secondary pinnse 

 and pinnules. The pinnules are not pedunculated as in the 

 drawing, but so far as the state of preservation of the specimen 

 shews, appear to be attached to the pinna by the whole of the 

 basal margin ; and on some of the pinna;, the pinnules are so 

 closely placed that they overlap each other, and it is difficult to 

 observe the real shape of the pinnules. It seems to me to be 

 allied to Schlotheim's species. The veining, as shewn on some 

 of the pinnules, of which the enlarged figure gives a more accu- 

 rate idea than it does of the shape of the pinnules, is very similar 

 to the vernation of the pinnules of Pec. Pluckenetii, Schloth. 

 The specimen seems to be unique, and as it is too imperfect to 

 admit of accurate description and presents many of the charac- 

 ters of the above species, I have no hesitation in referring it to 

 the above.
