CoralKan Plants. — A small nuinber of plants tave been obtained 

 from the Corallme Oolite of Malton in Yorkshire ; the most 

 abundant specimens are the Gymnospermous seeds described by 

 Lindley & Hutton' and other writers. The Malton Museum 

 contains some good examples ; others may be seen in the 

 British- Museum, the Manchester Museum, the York Museum, 

 the Museum of Practical Geology, London, and in several other 

 collections. Eeference is made to Malton plants by Blake & 

 Hudleston ^ in their paper on the Corallian rocks of England, and 

 in an appendix Carruthers" describes an interesting example of 

 an Araucarian cone, Araucarites Hudlestoni, preserved in the York 

 Museum. 



Kimeridgian Plants. — Eeference has already been made to the 

 Kimeridge Coal. In 1869 Carruthers' described a small cone 

 from the Kimeridge Clay of "Weymouth, which he named Pinites 

 depressus ; the type-specimen, which has almost fallen to pieces, is 

 in the British Museum (V. 6370). In 1892 Mr. George Mun-ay " 

 proposed the name Caulerpa Carruthersi for some specimens which 

 he believed to represent a species of the Siphoneous algal genus 

 Caulerpa, but, as pointed out in the sequel, it is probable that 

 the specimens so named do not owe their origin to algse. 



Class THALLOPHYTA. 



The British Oolitic rocks, at least those which are dealt with in 

 these pages, have not afforded any thoroughly satisfactory examples 

 of either Algae or Pungi. In the petrified tissues of coniferous 

 wood one constantly finds direct or indirect evidence of the 

 occurrence of fungi, but I am not aware of any examples of 

 this group worthy of record among the fossils in the Museum 

 collections. Several ' species ' of Algse have been described, but 

 none have any claim to be regarded as botanically important.
