un pen le genre Ptilophyllum des hides.’* And we Lave this liassic species in our Jabalpur 
group, which is of the same age as the Ivach series. 
There are about three or four specimens which closely resemble Ptilophyllum cutchense, 
Morr.; but they have no decurrent leaflets ; the base of the leaflets i< a little broader, sub- 
auricled, and subcordate, attached by the middle of the base only, the veins radiating in the 
leaflets, and forked within ; the leaflets closely set, alternating, having evidently all the 
characters of Olozamites, JL\, in which class Schimper has therefore right! v placed it. Dr. 
Oldham had already determined it correctlv. 
It still further proves the early age of our Jabalpur and Kaeh series. Our specimens 
are from the Sher river in the Satpnra basin. 
1 ■— Ptilophyllum, Morr. ( Palceozamia , F,ndZ.). 
This common genus of the upper portion of the Gondwana series occurs, and shows 
again the relation of this group with the others as belonging to the same epoch. Ptiloph. 
acutifolium, Morr., is the prevailing form. 
The only related form of Ptilophylhim , Schimper finds, as I mentioned, with the 
liassic OlozctwUes gracilis (Kim'.), Schimp., and just this genus is the most prevailing and 
most characteristic of the upper portion of the Gondwana series. 
Our specimens of Ptilophyllum dive from Saipura basin. 
1.— Williamsonia, eonf. gigas, Carr.f 
I have had occasion to mention this interesting and important genus from the Kach 
series, the Rajmahal series in the Rajmahal Hills, and from Golapili. It occurs also in the 
Jabalpur group. 
In pi. 53, f. 15, Mr. Williamson gives a section of the restored involucrum, with 
smooth pyriform axis supporting a superficial layer of oblong cells arranged vertically on 
its outer surface, and with this our specimen from the Jabalpur group agrees quite well, 
only that the layer of cells seems to be broader in the upper part. Outside, several of the 
lanceolate scales are well seen. I will range our specimens provisionally as Williamsonia 
comp, gigas, Carr. From the Satpuru basin. 
We have therefore amongst the Cycadeacece the following species of great importance : 
I .—Podazamites lanceolakts , L. & II. sp. Very frequent in all three districts; a 
lower oolitic species in England; represented in the rhsetie by Podozam. distune , Fresh 
2 -—Podozamites Hacketi, Fstm., from the Satpura basin. Nearly identical with the 
Australian Podoz. Barklyi, McCoy from mesozoic (oolite). 
3 —Otozamit.es comp, gracilis, Kurr.,J from the Satpura basin. In Europe an upper 
liassic form, related a little to Ptilophyllum, Morr. 
Ik.—Ptilophyllum acutifolium, Morr., from the Satpura basin. Prevailing in the 
Eajmahal series. 
5.—Williamsonia comp, gigas, Carr., from the Satpura basin. In England specially 
a lower oolotic species.
