last-mentioned, and is turned into or preserved in a car- 

 bonized state. 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 588). 



272. — A larger example shewing nearly the entire pericarp, fully two 

 inches in length, and at the top three divisions or lobes of the 

 pericarp are seen, but whether the top was divided into three 

 or six divisions the imperfection of one side of the specimen 

 at the top does not allow to determine. The basal part of the 

 outer surface with fine parallel lines. 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 579). 



273. This specimen shews the external appearance of the 



pericarp, with its top divided as in the last into apparently 

 three lobes. The general appearance of this specimen is like 

 that of the flower of a Crocus with the petals partially ex- 

 panded. 

 Loc. — Shale above the Bensham Seam, Jarrow, (H. C. 583). 



274. ' Section of the pericarp shewing the carbonized kernel 



and spike ; the inner surface of the pericarp with numerous 



fine elongated vessels of the fibrous lining. 



Loc. — Shale above the Bensham Seam, Jarrow. (H.C. 586). 



275. Section of a kernel with flattened, flanged margin all 



round, which passes upwards, at the apex, into a long flattened 



spike, more than an inch and a half long of thin carbonaceous 



matter. 



Loc— Shale above the Bensham Seam, Jarrow. (H. C. 580). 



276. Two impressions of the kernel (Trigonocarpoii) in coal ; 



one shews the dividing edge of two sides of the kernel pro- 

 duced into a sharp ridge, which is continued up into the spike 

 or bayonet-blade shaped continuation of the kernel to the top 

 of the pericarp. 

 Loc— Bensham Seam, Jarrow? (H. C. 590). 



277.— Carpolithes ? 



Five specimens of the kernel smaller than usual, apparently 

 belonging to this species, closely placed together. On the 

 same slab is portion of a stem with two somewhat circular 

 leaf-scars, which appears to be a fragment of the stem of 

 Cordaites regularis (Sternb. sp.). 

 Loc. — Shale above the Bensham Seam, Jarrow. {H. G. 592). 



Remarks. — The Hutton Collection contained a fine series of 

 specimens of Carpolithes alata, from which the above Type-
