We have here also again a form which begins in rhasticand goes into lower oolite. 
Our specimen is allied with both. From Jabalpur. 
III. — Pecopterides. 
This family is pretty frequently represented ; it also occurs both in Kach and in the 
Rajmahal series. 
Group of Alethopteris Whitbyensis, Gopp. 
Two forms represent this group, which is essentially lower jurassic. 
1. —•Alethopteris Medlicottiana, Oldh. 
Fronde tripinata, pinnis remotis patentibus, pinnulis integris, striatis ; e Iasi latiore 
lanceolatis, acuminates basi paulum sub decurrent ibus, fere contingentibus. Nervo medio 
distincto, nervis secundariis sub angitlo acuto aggredientibus dicliotomis. —(Diagnosis 
given by me). 
This specimen was recognised already by Dr. Oldham as differing from the others of 
this group. He proposed the name as above, which I will not change, although it has 
never been published, and I find it only in pencil on the original drawing. 
Our species differs from the allied forms in the pinnules . which begin with a broad base, 
but become much narrower, giving the whole plant a peculiar appearance; it may be closely 
allied with Pecopt. ligata, Phill.* 
2. — Alethopteris Wldibyensis, Gopp. 
This species we know already from Each ; in the present region it is more common 
and especially in the form described formerly by Brongniart as Pecopteris tenuis ,t which 
has, however, already been united by Unger and others with Alethopteris Whitbyensis, Gopp. 
As I have said, M. SchimperJ placed all these related forms to the group Alethopteris 
Whitbyensis, Gopp., considering it a truly jurassic typo. 
Mr. Saporta has done the same; only he established for all these allied forms a new 
genus, Cladophlebis, Sap., which would then contain the following species :— 
Alethopteris Rosserti, Aleth. Whitbyensis, dentata, Phillipsi, harburnensis, arguta, 
recentior, nebbensis, fyc., Sfc., establishing for all these a close relation, as I have shown in 
my Kach llora. 
Our specimens of Alethopt. Whitbyensis, Gopp., are from the Satpura basin. 
3. — Pecopteris comp. Murrayana, Bgt. 
A specimen from Jabalpur recalls this lower oolitic species. I found the same 
determination written by Dr. Oldham on the original drawing, which I will use in my 
detailed paper. 
Of the Pecopterides, therefore, all three species indicate a lower oolitic age. 
One is also found in Kach. 
IV. —Tainiopterides. 
Only some fragments represent this family, indicating one of those forms which 
Schimper placed in his subgenus Macrotceniopteris, reserving Taeniopteris for the 
Palaeozoic forms; amongst these, however, are also some which could he taken as Macro- 
taeniopteris, Schirnp. I only recall the specimen described thirty years ago by Gutbier as
