2. Aspidium Heerii , Ett., Plate XXXIX. figs. 4, 5. K. von Ettingshausen, die Farm 
krauter der Jetzwelt, p. 199. A. elongatum , Hr. FI. Tert. Helv. i. p. 36, pi. xi.

Fragments of pinnules, agreeing well with the fern of the Hohe Rhone. It differs 
from the preceding species in the pinnules, which taper at the apex, and the secondary 
nerves, which are apparently not forked. Figs. 5 & 5 b represent the pinnatisect ends 
of the pinnules. The pinnules are bent upwards, and the secondary nerves spring at 
acute angles. Fig. 5 b shows traces of sori. 
3. Aspidium ursinum, Hr., Plate XXXIX. fig. 6 a. Foliis bipinnatis (l) pinnulis ob- 
longis, subpinnatifidis, lobis rotundatis. Hab. Kudliset. 
A portion of a pinna. Rachis slender, bearing alternate, oblong-oval, and on the 
upper part obtusely rounded pinnules. Margin with large teeth, or rather short obtuse 
lobes, separated by shallow sinuses. Nervation obliterated, but only one undivided 
secondary nerve seems to run to each lobe (fig. 1 a a, magn.). 
4. Woodwardites arcticus, Hr., Plate XF. fig. 6. Hr. FI. Foss. Arct. p. 86, pi. i. fig. 16.

Fig. 6. Fragments of pinnatifid pinnules, lobes obtuse. Nervation well preserved, 
agreeing with pi. i. fig. 16 of my ‘Flora Arctica.’ 
5. Hemitelites Torelli, Hr., Plates XL. figs. 1-5 a ; LV. 2. Fronde bipinnata, pinnis 
pinnatifidis vel pinnatipartitis, apice attenuatis, lobis integerrimis, apice obtusius- 
culis, nervis tertiariis furcatis, inferioribus sinum attingentibus. Pecopteris Torellii , 
Hr. FI. Foss. Arct. p. 88, pi. ii. fig. 15. Hab. Atanekerdluk. 
Formerly I had but a small fragment of this species. Mr. Whymper’s specimens 
are much better, and give a good idea of this interesting species, but the sori are 
wanting. 
Stipes furrowed, pinnules alternate, tapered downwards and decurrent (Plate XL. figs. 
1, 2), long, deeply cut, entire, lobes rounded or obtuse, midrib pretty stout. Secondary 
nerves forming acute angles more or less curved, and bearing on each side 4-6 tertiary 
nerves ; lowest strongly curved, always entering the sinus between two lobes. The 
lowest tertiary nerves do not generally join those of the neighbouring pinnules (figs. 2, 3), 
but this is the case in fig. 4. 
Fig. 5 a. Portion of a very large pinnule, which belongs, I believe, to the same species. 
In the collection at Copenhagen is a remnant of this species showing that the leaf is 
bipinnate ; the rachis communis is large (11 millims. diam.), the pinnae approximate. 
(Plate LV. fig. 2.) 
This must have been a very large and luxuriant fern. It is very near Pecopteris 
( Hemitelial ) lignitum , cf. Lignites of Bovey Tracey, p. 29, pis. iv. figs. 4-6 ; v. 1-11 ; vi.,
