 Lepidodendron aculeatum, Kidston, Catal. Palceoz. Plants, p. 153. 

 Lepidodendron aculeatum, Zeiller, Flore foss. d. Bassin houil. d. Valenciennes, pi. lxv. 



Remarks. — Frequent. 



A specimen in the roof of one of the workings of Braysdown Colliery, of 

 which a piece was shown me by the manager, Mr Steart, was 40 feet long, but 

 as both its upper and lower extremities were embedded, its complete length 

 could not be ascertained. At some of the other collieries, fragments of very 

 large stems were also seen. 



Localities : — Radstock ; Braysdown Colliery ; Wellsway Pit ; Camerton. 



Lepidodendron Worthenii, Lesquereux.

 Lepidodendron Worthenii, Zeiller, Flore foss. d. Bassin houil. d. Valenciennes, pi. lxxi. 



Remarks. — This species is comparatively common in the Radstock Series. 

 Localities: — Radstock; Wellsway Pit ; Braysdown Colliery ; Camerton. 



Lepidodendron lanceolatuni, Lesquereux. 

 Plate XXVII. fig. 5; Plate XXVIII. figs. 3, 4. 



Lepidodendron lanceolatuni, Lesqx., Coal Flora of Pennsyl., p. 369, pi. Ixiii. figs. 3-5. 



Description. — Scars lanceolate or broadly fusiform, smooth, keeled ; vascular 

 cicatrice small, situated in upper part of scar ; cicatricules indistinct. Leaves 

 lanceolate, acute, slightly curved. 



Remarks. — None of the specimens of this species with which I have met 

 give a clear view of the vascular cicatrice, nor does it appear to have been well 

 seen in Lesquereux's specimen. His enlarged fig. 5 has been probably taken 

 from an imperfectly preserved example, and seems to represent a leaf-scar, 

 from which the leaf has been forcibly torn. 



What I regard as the cone of this species is shown at PI. XXVII. fig. 5. 



Localities : — Radstock ; Camerton ; Upper Conygre Pit ; Braysdown.
