RADSTOCK SERIES OF THE SOMERSET AND BRISTOL COAL FIELD. 363 



Odontopteris, Brongniart, 1822, Sur la classification des vegetanx fossiles, 



p. 34. 



Odontopteris Lindleyana, Sternb. 



Odontopteris Lindleyana, Sternb., Vers., ii. p. 78. 



Odontopteris obtusa, L. & H. (not Brongt.), Fossil Flora, vol. i. pi. xl. 



(?) Odontopteris heterophylla, Lesquereux, Geol. Rep>. of Illin., vol. ii. p. 433, pi. xxxviii. figs. 2, 5. 



(?) Odontopteris heterophylla, Coal Flora of Pennsyl., vol. i. p. 129, pi. xxii. fig. 6. 



Remarks. — The type of Lindley and Hutton's species is preserved in the 

 University Museum, Oxford, but the figure given in the Fossil Flora is not a 

 very correct representation of the specimen. 



Odontopteris Lindleyana is very rare in the Kadstock Coal Field, but occurs 

 more plentifully in the shale over Pontydwaith Seam, Pochin Pit, near 

 Tredegar, South Wales. The examination of the type and the additional 

 specimens from Radstock and South Wales has shown that Lesquereux's 

 Odontopteris heterophylla is probably identical with the plant figured in error 

 by Lindley and Hutton as Odontopteris obtusa.
