14 ON GYMNOSPERMATOUS FRUITS 
The specimen is from the Lower Greensand at Selmeston, Sussex. 
6. P. Dunkeri, Car., Geol. Mag. iii. 542. Cone elongated, cvlin- 
drical; scales broad, with a rounded and thin apex; axis slender; 
seeds oval, compressed.*— 4fi*tite$ Dunkeri, Mant., Geol. Isle of Wight, 
2nd ed. p. 452, 3rd ed. p. 337, Lignographs 43 and 42-, fig. 5 (ex- 
clude fig. 1-4 and 6, which belong to a Cycadean fruit) ; Med. of 
Creation, p. 179, Lign. 61. 
There are many specimens of this species in the British Museum. 
This is a very remarkable cone, little more than an inch in diameter, 
yet attaining a length of thirteen inches. The cones have generally 
opened before they were buried in the sand in which they are pre- 
served, and as the sand has penetrated between the expanded scales, 
they are always broken when the fossils are exposed, their apices still 
remaining in the piece of rock which has been separated, just as the 
scales on the side of the cone are seen to penetrate the rock in which 
the fossil is imbedded (Plate LIX. Fig. 2). This condition and aspect 
of the cone has led Mantell into the error of supposing that it was 
furnished with large foliaceous bracts, which he has represented in his 
somewhat restored figure in the ' Medals of Creation,' p. 179. I was 
fortunate enough to remove the stony matrix from one of his speci- 
mens, which had been buried unopened, and which exhibits the form of 
the scales (Plate LIX. Fig. 1). The apices are rhomb-shaped, but 
with the upper angle somewhat rounded. There is no indication of 
bracts. The fossil has the aspect of a very elongated and cylindrical 
cone of Pinna Abies, L., to which it is evidently nearly allied. 
This species has been found in the Wealden of Tilgate Forest, and 
of 3 -5 rook Point, Isle of Wight. 
There are fragments of two cones from Brook Point in the British 
Museum, the one more slender than P. Dunkeri, and the other beiBg 
at least twice its diameter, but whether they belong to this species or 
are different the materials are not sufficient to determine. 
7. P. Mantellii, Car., Geol. Mag. iii. 543. Cone ovate-acuminate; 
scales broad, flat, and thin at the apex; axis slender; seeds roundish 
(Plate LIX. Fig. 3). 
This cone is about an inch and three-quarters long, by fully three- 
quarters broad. The specimen is fragmentary, but the form of the 
cone is preserved in the matrix. The apex of the scale is very broad 
and thin.
