PLATE XXXI. 



Sphenopteris latifolia. 



Bkong. Yar. 



Another, but very different variety of this species. In 

 the absence of venation little need be said respecting this 

 specimen, which, like the last, conies from the shale roof 

 of the Bensham seam, Jarrow Colliery. 



The drawing is by Prior, and is, like our figure, of the 

 natural size. 



The Pecopteridian affinities (as to form) of this variety 

 will be readily observed.
