In WiUiamson's papers read before the Geological Society in 

 1834 and 1836,' a list is given of Oolitic plants, but one of the 

 most important additions to the geology of the plant-bearing strata 

 in these contributions is the correction of Phillips' mistake as to 

 the horizon of the Gristhorpe plant-bed. 



An important paper was read before the Geological Society of 

 London in 1851 by Bunbury,* On some Fossil Plants from the 

 Jurassic Strata of the Yorkshire Coast, in which several species 

 are critically discussed, and illustrated by accurate drawings ; the 

 species specially referred to include the following : — 



Sphenopteria nephrocarpa, Bunb. (Type in the Leckenby Collection, Cambridge.) 



= Coniopteris hymenophylMdes (Brongn.).
