FROM TIIK BUTTON COLLECTION. 95 



176. A very fine bifurcating small branch shewing leaf-scars 



and leaves. 



Loc— Shale above the Bensham Seam, Jarrow. (H.C. 347). 



177. — Lepidodenclron elegans, Brongt., L. et H. 



Very fine impression of leaf-scars on portion of a large branch ; 

 the scars well preserved, and in size and shape very similar to 

 those of L. dilatatum, L. et H. 

 Loc— Shale above the Low-Main Seam, Felling. (H. C. 336). 



178. — Lepidodendron dilatation, L. et H. 



Three rows of casts of leaf-scars with leaves attached of L. 



Sternbergii. The inner surface of the scars shewn. 



Loc. — Shale above the Bensham Seam, Jarrow. {H.C. 324). 



179. — Lepidodendron obovatum. Sternb. 



A small but fine fragment of leaf-scars in clay-ironstone shale 

 of this species. 



Loc. — Uncertain, but like specimens from the neighbourhood 

 of Durham (city). (H. C. 344). 



180. — Lepidodendron Sternbergii, Brongt., L. et H. 



Small slab of shale covered with numerous spore-capsules, 



spread separately over the surface. 



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



Fructification. 

 181. — Lepidostrobus variabilis, L. et H. Type specimen, F.F. , pi. 10, f . 2. 

 This slab is nearly covered with portions of strobili, but only 

 four are figured ; one small cone on the left of pi. 10, f. 2, 

 two sections of cones and an imperfect cone near the lower 

 margin of the slab. The sections on the slab are of most 

 interest. There are two labels on the back of the slab ; one 

 illegible, the other, " Wm. Hutton. To be returned." The 

 specimen was found in the collection without a legible, scien- 

 tific name on it. 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 431). 



182. , L. et H. This specimen has two of Hutton's labels on 



it, " L. variabilis, Jarrow, B. P., 10 and 11," but neither of 

 the two cones on the slab can be identified with any of Hutton's 

 figures in Fossil Flora. There is on the left hand side of the 

 slab a small cone, about three inches long and an inch wide, 

 and to the right a cross section of a cone shewing the cen- 

 tral axis, and the remains of spore-scales arranged round and 

 radiating from the centre. 

 Loc— Shale above the Bensham Seam, Jarrow. (H.C. 438).
