long and 2 to 3 millims. wide ; at both ends they are obtusely rounded, and at one 
end are furnished with a small round hole (fig. 33, magnified fig. 34 ; fig. 35, magnified 
fig. 36), which is only -visible in those specimens that are compressed from above. The 
sides are furrowed by very delicate and elegant longitudinal strise, formed by the cells, 
which are arranged in lines. They are neatly crenated and very delicately dotted (cf. 
fig. 37, a highly magnified piece, of which only part of the testa has been preserved). 
This elegant sculpture can only be made out by the aid of a lens or microscope. 
They are very much like the seeds of Nyrrij^Jicea alba, especially the form with the larger 
seeds, the Nymjylicea alba melocarjya, Casp. In the recent seeds the longitudinal striae 
appear much less distinct ; but in such seeds as are found in the ‘ Pfahlbauten’ of 
Kobexhausex, they look exactly like those of the fossil species. In these also the 
hole on the top of the seed is somewhat more widened, as in the fossil species. As to 
the shape, the latter differs in so far as the seeds are comparatively somewhat wider 
(those of alba melocarjya are 3 J millims. long and 2 millims. wide) : this more con- 
siderable breadth may have been caused by pressure, since they are all highly com- 
pressed. To the same circumstance we may ascribe the fact that the raphe cannot be 
pointed out distinctly. 
The seeds of Bovey are very like those of my Nym^hcea Charpentieri (Flora Tertiaria, 
iii. p. 195, pi. 155. fig. 20 b, c), the latter being only somewhat narrower. It would 
therefore be very desirable that the leaves be sought for at Bovey, since from these 
alone can it be decided with certainty whether this species is really distinct from 
N. Charpentieri, to which it comes very near. The seeds of the li-ving NymphcBce are 
variable in their dimensions.

As at Bovey only fragments of leaves have been found, no sure determination can be 
given. The leaves are smooth, shining, coriaceous, somewhat incurved, and taper 
towards the tip. The secondary nerves are very delicate and form arches, which run 
nearly parallel with the margin. Close by the leaf (represented in fig. 9) lies the top 
of a leaf of a quite different plant, which seems to belong to Quercus I/yelU’
