parisoD with the Clee Hill fossils, and this showed conclusively that they could not 

 be referred to Sphenopteris trifida Gopp. sp., but were an undescribed species. 



From Splienopteris trifida it differs in the ultimate pinnae being even more 

 linear. On many of the pinnae (probably the upper ones) the pinnules arc bifid 

 (rigs. 3, 3a), on others and probably lower pinnae they are trifid (figs. 4 and 5) ; the 

 pinnules consisting of two lateral linear segments and a distinct terminal one ; 

 whereas on Sphenopteris trifida the pinnules might be described as cuneate, with 

 three teeth on the upper margin, as seen in Goppert's original enlargement ; and the 

 same character can be seen on Stub's two figures if examined with a lens.* 



1 have pleasure in naming this species after Mr E. E. L. Dixon, B.Sc, F.G.S., to 

 whom I am indebted for my knowledge of the flora of the Clee Hill Coal Field.

APPENDIX. 



LIST OF THE FOSSIL PLANTS COLLECTED FROM THE CORE 

 OF THE CLAVERLEY TRIAL BORING, 



Five Miles East of Bridgnorth, Shropshire. 



As only incidental reference has been made to the fossil plants collected from 

 the core of this boring, t it has been thought desirable to publish a complete list with 

 the depths from which they were obtained. 



A description of the core, accompanied by a section, has been given by Dr Walcot 

 Gibson when dealing with the geological and economic problems suggested by this 

 boring,| and an abstract of the section is given here by Mr Cantrill on p. 1010.
