746 MR ROBERT KIDSTON ON THE EOSSIL PLANTS OF 



The Sphenopteris bifida, Schmalhausen,* is, however, a distinct species from the 

 Sphenopteris bifida, L.and H.,and the name has evidently been adopted by Sohmalhausen 

 for his plant, which comes from the Permian, by an oversight. 



Localities. — Glencartholm, Eskdale ; Kershope Burn and Tweeden Burn, Liddesdale.

Remar ks.— Some years ago the late Mr Howsk, Curator of the Natural History 

 Museum, Newcastle, called my attention to the specimen figured by Lindley and 

 Hutton under the name of Sphenopteris linearis, Brongt. t Their specimen is not 

 Brongniart's plant, but an exceedingly fine example of the upper portion of a frond of 

 Sphenopteris crassa, but the plate is not a satisfactory rendering of the fossil. 



Localities. — Docken Beck, near Langholm ; Glencartholm, Eskdale ; and Tinnis 

 Burn, Liddesdale.

Remarks. — The specimen placed here is the terminal portion of a pinna. It agrees 

 well with Goppert's figures of the var. stenophylla, which I believe to represent the 

 upper portion of the frond. Reference has already been made to the difficulty of
