FROM THE SECONDARY ROCKS OF BRITAIN. 13 
is accurately figured by Mantell ; but the artist, in restoring the exter- 
nal aspect, has made the exposed apices of the scales nearly equal- 
sided, whereas, in the specimen, they are at least four times broader 
than they are deep. The axis occupies somewhat more than a third 
of the diameter of the cone. The position and shape of the seeds, 
the form of the scales, the shape of the exposed apices, and the general 
aspect of the cone, are very like those of a Cedar. It may be compared 
with Finns (Cedrus) Atlantica, Endl. 
5. P. Snssexiensis, Car., Geol. Mag. iii. p. 541. Cone oblong, trun- 
cate at both ends ; axis slender; scales leaving the axis at a very acute 
angle, bearing two ovate seeds in a hollow, very near the base; scale 
in transverse section triangular.

The specimen, which is the one described and figured by Mantell, is 
5£ inches long, and nearly 2 inches diameter. The apex is almost per- 
fect, but the base wants one or more whorls of scales ; the small stalk 
referred to by Mantell is a portion of the axis from which the absent 
scales have fallen. The cone is so much decayed on the outer surface 
that the apices of the scales are mostly absent ; but a portion which 
still retains some of the matrix in which it was preserved seems to 
show the form of the apex. It was a flat scale, like that of Pinus 
Strobus, L., but the superior margin had a tumid border, without any 
terminal umbo. The scales in transverse section, as exposed on the 
w r eathered surface, are sub-triangular as figured by Mantell, and on the 
upper portion of our Fig. 5. The axis is slender, and the scales on 
leaving it take at once their ascending direction. The two narrow 
■ 
ovate seeds are borne very near the base of the scale, in a cavity sunk 
into it. The two cavities shown in Fig. 5, are formed by the testa of 
the seeds, the contents having disappeared. 
Mantell submitted a plaster cast of this fossil to Brongniart, but as 
might have been expected, that distinguished palaeontologist was 
unable, with such materials, to determine anything positive in regard 
to it. Mantell had no hesitation in referring it to Zamia, as a fruit 
of that genus, and every subsequent writer has followed him. The 
fossil certainly belongs to the Pinus division of the genus, and is near 
to Pinus Strobus, L.
