in the Sikkim Province, south of Darjeeling (Darjiling), and some of the 
highest beds are also represented in the Kach Peninsula, north-west of 
Bombay.” 
In the above paper, as well as in the 2nd Part, Vol. IY, of my 
Gondwana Plora (188G), I have found it more convenient and natural to 
subdivide the whole coal and plant-bearing system, called the Gondwana 
System, into three divisions. 
A. — Upper Division of the Gondwana System.* 
Jabalpur ( Umia Group, Kach. Tripetty Sandstones. Chikiala Sand- 
Series. v stones. Jabalpur Group. Bagra Group. 
Intermediate 
Series. 
C Chari Group, of Kach. Denwa Group. Kota-Maleri beds. 
*< Sripcrmatur Group. Bagavapuram. Vemaveram. Utatur 
( plant beds. 
Rajmahal ( Bajmahal Group— Atgarh Sandstone. Sironcha Sandstone. 
Scries. t Paclnnari Sandstones. Dubrajpur Group. 
This Upper Division is especially characterized by plant remains, such as 
Gleichenia , Piclcsonia, Alethopteris (Asplenium) , Tliinnfeldia , Macrotccniop- 
teris , Angiopteridium, Pterophyllum, Anomozamites, Ptilophyllum, Olo~ 
zamites, Cycadites, Pa Ussy a, Taxites, &c. Also some animal remains occur 
in some beds of the Intermediate Series, such as Ceratodns , Lepidotus, 
Tetragonolepis, Ilyperodapedon , Parasuchus, P do don, &c. In the upper- 
most group (Kach Group) there are marine animals of uppermost Jurassic 
type, and a flora of Middle Jurassic character. 
B. — Middle Division of the Gondwana System — some uncertain transitional 
beds. 
Panchct Series. — Panchet Group. Almod beds. 
Damuda ( Mangli shales. Karnthi Group. Itaniganj Group. Bijori 
Series. (. horizon. Ironstone shales. Motur horizon. Barakar Group. 
The fossils of this division consist of animals and plants. The animal 
remains, especially in the Panchet Group, Mangli Shales and Bijori horizon, 
are represented by the genera JEstheria, Gonioglyptus, Pachygonia, Glyptog- 
nathus, Picynodon, Ppicompodon, Prachyops, and Gondwcinosaurus. Of 
plants the following genera are known : — Sdiizoneura (frequent), Phyllotheca, 
Trizygia, Vertebrarici (numerous), Alethopteris, Merianopteris, Macro treniop- 
teris, Palceovittaria, Glossopteris (very numerous), Gangamopteris (rare), 
# This name, as well as those of the three Series of the Upper Division, have been introduced by me into 
the literature.
