PLATE XLIV. 



(?) 



Another very vague specimen which Lindley declined 

 to name, his memorandum respecting it being: — " too 

 imperfect." The drawing was, nevertheless, intended 

 for publication. It came from the Bensham coal-seam 

 horizon, Jarrow Colliery. 



Our figure is slightly reduced from that of the original 

 drawing by Peioe.
