PKOM THE HUTTON COLLECTION. 99 



have near me a specimen of Phytolithus verrucosus from the 

 Somersetshire Coal-field, which is exactly like Mr. Kidston's 

 figure, Plate 38, f. 10, in the work just quoted, and which 

 does not, I think, belong to Sternberg's illustration of Lepido- 

 dendron Anglicum. 



The Lep. rhombicum, Lesqx., Coal Pits. Penns., pi. 62, f. 4, 

 comes close to this, if it be not identically the same species, but 

 his figure appears to be from a branch or part of a younger stem. 

 I have not been able to examine a figure of Lep. serpentigerum, 

 figured by Konig, which species is, in the British Museum Cata- 

 logue, recorded from this Coal-field. This species occurs also in 

 connection with the thin seams of coal which are intercalated 

 with the upper beds of the Carboniferous-Limestone of Northum- 

 berland.

188. — Lepidodendron rimosum, Sternb. 



Very fine impression of elevated casts of leaf -scars ; the upper 

 and lower parts of each scar with transverse wrinkled lines. 

 The leaf-scars are separated by narrow bands of grooves, 

 which are the impressions of the vascular bundles which sur- 

 round each leaf-scar. This is the L. rimosum of Sternberg 

 and others. 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. — ).
