[VOL. IS 
c. —Pecopteris ( Asplenites) macrocarpa, Oldh. and Morr., PI. XXVIII, is an Asplenites 
very near to Asplenites Ottonis, Schimp., also from the R h 031 i c (Bavaria); important. 
d. —Pecopteris lobata, Oldh. and Morr. PL XXIX, XXX, pretty frequent; it may 
retain this name; it seems an Indian type. 
4.—Order Tcsniopterides. 
This family gives one of the chief characters of the Rajmahal series, especially in the 
Rajmahal hills; there are very frequent large and interesting forms which are very 
important for the determination of the age. 
a. —MaeroUmiopteris (Tmniopteris) lata , Schimp., (Oldh. and Morr.) PI. I, II, IV, 
Tceniopteris musesfolia (Oldh.) Schimp., which are not really different, represent the 
character of this family, being very near to Tceniopt. (Macrotceniopt .) gigantea, Schimp., 
from the R k re t i c. 
b. — Tceniopt. ( Angiopteridium) MeClellandi, Oldh. and Morr., PI. VI, (Tceniopt. 
spatlmlata, MoClell.), being near to Angiopteridium {Tceniopt.) Munsteri, Schimp., from 
the R hoe tie, these two fossils indicate a lower age for this series than that hitherto 
supposed. 
p.— Tceniopt. ova/a, Schimp., described as Tceniopt. ovalis (Oldh. and Morr.), hut 
different, as I find by the denticulation of the margin. 0. M. PI. Ill; Fstm. PI. 
XXXVII, f. 1. 
d. — Macrotceniopt. Morrisi, Oldh., is also a separate species. 0. M. PI. Ill, IV. 
c. —Tanaopsis Rajmahalensis, Fstm. PI. XXXVIII. 4. The essential characters of 
this very interesting genus are, I believe, exhibited in this species. 
In the Cryptogamae we may, therefore, note as important JSquisetum Sajmahalense, 
Schimp., ThimfelJia irulica, Fstm., Alethopteris indica, Oldh. and Morr., Alethopt. 
macrocarpa, Oldh. and Morr., Macrotceniopteris lata, Oldh., and Angiopteridium 
MeClellandi, Oldh. and Morr. 
B.— Phanerogam.®—Cotyledohes. 
1.— Zamiece. 
In this class we find another marked character of the Rajmahal series, by which again 
this flora differs quite distinctly from that of the Ivach series. 
a - — Pterophyllum, Bgt. The most devekqicd genus, with a great variety of forms, 
of which the most characteristic are Pterophyllum carterianum, Oldh., Pterophyll. Mor- 
risianum, Oldh., Pterophyllum princeps, Oldh. and Morr. (which is quite near to PteropK. 
Braunsi, Schenk, from the Rhcetic), Pterophyll. Rajmahalense, Morr. &c., as they have 
been described and figured by Oldham and Morris. PL X, XVII1. 
b- Ptilophyllum, Morr. About this I have already said that I take this name instead 
of Palcsozamia, Rndl., observing it as an Indian type, and therefore as a distinct genus ; 
this genus is known both in the Each and the Rajmahal series ; and also the same species 
occur in both ; but while Ptiloph. Qutnhense, Morr., prevails in Each, Ptiloph. aeutifohum, 
Morr., is the most abundant in the Rajmahal series. Ptilophyll. rigidum, Schimp., I take 
to be identical with this latter, and think Ptilophyll. {Palcsozamia.) affine, n. sp., not very 
far from Ptilophyll. Cutchense, Schimp. As varieties I distinguish here also Ptiloph. 
acutifoliuni yar maximum and Ptiloph. Cutchense var minimum; this genus constitutes a 
connective form between these two rock-series, belonging to the same great geological 
epoch; it is Jurassic.
