Vol. 65.] FOSSIL PLANTS EROM THE KENT COALFIELD. 27 



of certain JS T europterids, are met with occasionally in various beds 

 in both series. It is not, however, possible at present, owing to 

 the fragmentary condition in which all fossil plants occur, to refer 

 them to the species of frond that bore them.

This plant, which is not infrequent in the "Waldershare Series,, 

 has been so rarely figured, that I include a figure of the best 

 specimen from Kent on PI. I, fig. 4. Dr. Kidston ' L has stated that 

 the figure given by Lindley & Hutton ' is not a very correct 

 representation of the specimen.'

This species appears to be more abundant in the Fredville than 

 in the Waldershare Series.

This species appears to be rare, or at any rate much less- 

 abundant than A. lonchitica (Schloth.).

These specimens of seeds, which in some respects resemble 

 certain states of preservation of Trigonocarpus jparMnsoni, are too. 

 badly preserved to be specifically identified,
