question. The form and kind of tapering at the base agree, but it has more numerous 
and more crowded secondary nerves. 
I found m the 26th bed at Bovey several fragments of bark which probably belonged 
to an oak, and therefore might belong to the species in question. The bark is very thick 
and corky, provided with deep longitudinal furrows, and in some places fuiTowed trans- 
versely (cf. Plate LXVllI. fig. 6).

I have ah’eady mentioned in my ‘ Flora Tertiaria ’ (ii. p. 64) that the leaves of many 
lining species of fig-trees (I allude to the species which have leaves similarly shaped to 
Ficus fulm, Spr., F. 7'ubra, Spach, F. fermginea^ Desf , and F. phytolaccoefolia, Hort. 
Berol.) have a granulated appearance and a rough surface due to numerous little 
warts which cover the epidermis, and that the tertiary flora of Switzerland also pos- 
sessed two species, the leaves of which had the same rough surface. It is very curious 
that tliere are in the 26th bed at Bovey leaves which are granulated in this manner; and 
one of them is very near to Ficus scahriuscula. Hr. I therefore believe that I am not 
mistaken in ranging these three species under the genus Ficus. The following facts 
indicate that the granulation belongs to the leaf and not to the stone: — 1. The stone 
certainly is finely granulated ; but these granules are larger than the small points of the 
leaves, which can only be seen with the aid of a lens, and which are all of the same size ; 
2. they are regularly spread over the surface of the leaf; 3. they are on all the pieces 
of this species, but not on the leaves of other plants (e. g. Oinnamomum lanceolatum, 
Faphnogene TIngeri, and Lastrma Bunhurii\ which are lying in the same clay.

F. foliis coriaceis, magnis, confertissime granulatis, elliptico-lanceolatis, apice longe 
acuminatis, nervis secundariis subtilissimis, remotis, valde curvatis. 
The leaf represented in Plate LXIV. fig. 7 is the best preserved. The upper part is 
quite perfect, but the base is wanting. It is entire, and 12 millims. wide in the middle ; 
it is gradually tapered towards the apex, forming a long narrow point. The secondary 
nerves are very delicate, and there are but few to be discovered with the lens. They 
are strongly curved, and form arches, which are far from the margin. The areas are 
divided by very delicate nervules, and filled up with a very delicate reticulation. The 
rigid points which cover the whole surface are very small, and only to be seen with a 
strong lens. Plate LXIV. fig. 6 is the point of the leaf, the secondary nerves of which 
are more distinct. 
It is still doubtful if the leaf represented in Plate LXIII. fig. I « belongs to this 
species. It shows the same peculiar sculpture (cf. fig. I a «), and also very delicate 
secondary nerves ; but they approach nearer to the margin, and are much less directed
