that the Sphen. Geihiei of Kidston, Trans. Eoy. Soc. Edinb., Vol. 

 30, pi. 30, f. 5, is only a young, succulent, growing and not 

 fully developed frond of the same species. It seems probable 

 that the fragments figured by Hutton and others are only small 

 portions of a very large frond.

93. — Sphenopteris linearis, L. et H. Type SPECIMEN, pi. 230. . 



Specimen from the fresh-water limestone of Burdie House. 

 Leaves wedge-shaped, with fine radiating nervation, and the 

 pinnules closer and not so much lobed as in Hutton's figure, 

 which very imperfectly represents the original. The specimen 

 is in a dun-coloured, impure limestone. 

 Loc. — Calciferous sandstone, Burdie House, near Edinburgh. 

 (H. C. 175). 



Remarks. — While there can be no doubt that the specimen No. 

 93 mentioned above is the Type of Hutton's plate 230, yet the 

 figure is so unlike the original that no one would at first sight 

 think it was drawn from the above specimen. The draughtsman 

 has certainly given a much too free scope to his imagination and 

 neglected the original. The impression is very imperfect, most 

 of the pinnules on the lower side being broken off ; the pinnules 

 are flattened and wedge-shaped, and not lobed as in Hutton's 

 figure. The specimen itself is a small portion of a very large
