PLATE XV. 



Fragment of Neuropterid-Frond (?). 



Referring to the drawing, of which this Plate is a 

 faithful copy, Hutton wrote to Dr, Lindley as follows, 

 in a note dated the 15th November, 1835 : — " A beau- 

 tiful fern, from the roof of the Ben sham coal-seam, in 

 Jarrow Colliery, of which this fragment is the only in- 

 dication I have seen. The impression is on a coarse 

 micaceous schistus, which has not preserved any other 

 marks of the veining than the drawing represents." 

 (HuttonMSS.) 



The drawing is by Prior. 1
