not yet critically examiued ; and it is very possible that the full examination of th & fauna may 
modify the strati graphical relations as deduced from the cephalopoda, and then the “ palaeon¬ 
tological contradiction” would not be so strong. To show this, and to explain my point of 
view, the following observations may he given :— 
1,—There are certainly some mollusca that are generally of older age than Portlandian, 
passing into the higher beds of Ivach. 
a. —I may mention only from the Umia group (which contains the Portlandian cephalo¬ 
poda) the very frequent occurrence of— 
Goniomya-V-scripta, which mostly occurs in middle jurassic beds in Europe. 
Astarte major, Sow., very near with Astarte maxima, Om., from Middle Jura in Ger¬ 
many. 
A Trigonia near Trigonia Van, Sharpe, from jurassic beds on the Sunday River in 
Africa. 
A Goniomya scarcely different from Goniomya inflata, Ag., a Middle Jurassic form—■ 
also related with Goniomya rhombifera, Goldf., from Liassie strata. 
A Trigonia very near to Trig. TLerzogii, Hausm, from Enon on the Sunday River in 
South Africa. 
Some Trigonice allied with Tr. ventricosa in South Africa. 
A portion of the lower jaw junction of a Plesiosaurus, which has mostly allied forms 
in the English Lias—found near Borooria in the Umia group. 
hi —Erom the Charee and Katrol beds of Each, which are especially taken as represent¬ 
ing the Oxford group and Callovian, we have especially to mention Mtonotis inceguivalvis. 
Sow., in Europe generally of Liassie age—here in the Charee beds. 
Monolis Munsteri, Goldf., generally in Europe from Middle brown Jura here in the 
Katrol group which is talceu as representative of the Upper Oxford group. 
Pttrasuchus, a vertebra of that Crocodilian fossil which is looked upon as Triassic, 
and which occurs frequently with the Jabalpur flora near Maleri, which latter is identical 
with our Kach flora. 
Near Nurha, in the Katrol beds (therefore below the common plant horizon), the follow¬ 
ing fossil plants occur :— 
Sphenopteris arguta, L. & H., from Inferior Oolite in England In India occurs 
in the Rajmahal Series (Rajmahal Hills) and in the Jabalpur group. 
Alethopteris Whitbyensis, Giipp., in the form as Pecopteris tenuis, Bgt., from 
Inferior Oolite in England. Also at Kukurbit and in the Jabalpur group. 
Otozamites comp, contiguus, Fstm.—A similar form from Kukurbit. 
Araucarites Kachensis, Pstm.—a smaller specimen of this frequent species at 
Kukurbit and in the Jabalpur group. 
These plant remains are mostly identical with the others from Kach and the Jabalpur 
group. 
2. There is a great affinity of some of the fossils in the uppermost beds of Kach with 
forms from the South African strata on the Sunday and Zwartkop rivers as already men¬ 
tioned ; and also Dr. Waagen* refers a Trigonia from the Umia beds to the Trig, ventri¬ 
cosa, Kr.
