The volume of Illustrations of Fossil Plants edited by Professor 

 Lebour, consisting of autotype reproductions of drawings prepared 

 for Lindley & Hutton, contains two plates of Lower Oolite plants : ~

(PhilL).

In Williamson's papers read before the Geological Society in 

 1834 and 1836, 3 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 Coaat, in which several species 

 are critically discussed, and illustrated by accurate drawings ; the 

 species specially referred to include the following : 



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



= Coniopteris hymenophylloides (Brongn.). 

 Baiera gracilis, Bunb. (Type in the Bunbury Collection, Botanical Museum, 



Cambridge.) = Baiera gracilis.

 Peeopteris ciespitosa, Phill. = Laccopteris polypodioides (Brongn.). 

 Acrostichites Wittiamsoni (Brongn.) = Todites Williamsoni (Brongn.). 

 Peeopteris ezilis, Phill. [Bunbury's figured specimen is in the Botanical Museum, 



Cambridge; refigured, Seward (94), p. 197.] = Klukia exilis (PhilL).
