410 MR ROBERT KIDSTON ON THE FOSSIL FLORA OF THE 



APPENDIX. 



The Fossil Flora of the Farrington, New Rock, and Vobster Series has not 

 been nearly so fully worked out as that of the Radstock Series, but still 

 sufficient has been done to make a record of the species known to occur in 

 these horizons of considerable value. 



In none of these series are fossil plants so plentiful as in the Radstock 

 Series, hence the difficulty of working out their flora, — in fact, it can only be 

 done satisfactorily by those residing in the neighbourhood, who can take 

 advantage- of collecting when shafts are being sunk or new roads being driven 

 underground, or when in any other mining operations good fossiliferous shales 

 are met with. Some of the localities at the time of my visit appeared to be very 

 barren, while at other times I know they yielded a very good harvest. 



Next to the Radstock Series, the Farrington Series is that from which I have 

 collected most, but the time devoted to it has been small compared to that 

 given to the examination of the Radstock Series. I may remark in passing, 

 that paloeontologically the Farrington Series cannot be separated from the 

 Radstock Series, of which, in fact, they seem to form a part. 



The records from the New Rock and Vobster Series are chiefly obtained from 

 the study of specimens in the museums already referred to ; but I am also 

 much indebted for information regarding the flora of these series to Mr E. 

 Wethered, F.G.S., Cheltenham, and to Mr S. Jordan, Clifton, who kindly gave 

 me every facility for examining the fossil plants in their collections. 



The Pennant Rock seldom yields well-preserved examples, owing to the 

 coarse-grained nature of the rock. Any specimens seen were usually coarse 

 casts of Catamites or Lepidodendra. 



The Red Shales which separate the Radstock and Farrington Series are 

 also very barren, but the plants observed were similar to those of the two 

 series just mentioned. 



The flora of these various horizons are treated of in descending series : —
