dtis and Hyperodapedon, with these beds ; and I am inclined also to refer to 

 them some other red clays found in the Pench valley, north of Chhind- 

 wara, and in the Tawa valley, near Kesla, north of Betul* The Maledi 

 beds are also found in the Wardha river, near Porsa, between Chanda and 

 Maledi, and in South-east Berar, west of Chanda. In all these instances, 

 the clays are interstratified with soft white felspathie sandstone, and are 

 remarkably similar to those found in the typical locality near Raniganj, 

 where, however, they are associated with very micaceous sandstone. In 

 the Pench valley nodular limestone also occurs, but it is wanting to the 

 south. There is certainly no resemblance in mineral character between 

 the Kamthi beds and the Panchets in all these localities, which encircle 

 the Nagpur beds at a distance much as the Damiida localities do. 

 There may be some slight resemblance between some of the beds in the 

 " Upper Panchets" of Bengal and the Kamthi beds. But in cases where 

 mineral character is called in as evidence of the identity of rocks in 

 widely separated localities, something more than a slight resemblance 

 is necessary. There may be a slight resemblance between the red clays 

 of the Panchets or the red shales of the Panchet hill rocks and the red 

 compact shales of Kamthi, and some of the sandstones are similar, but 

 so are some of the Damuda sandstones ; but still the Panchets are very 

 unlike the Kamthis. On the whole, I consider that, judging from mineral 

 character, the Kamthi beds must be distinguished from the Panchets. 



The fossil evidence is more satisfactory. Sir C. Bunbury has identified 

 the Glossopiiens Browniana, Brogn., of Nagpur, with that of the Damuda 

 beds. Several other figures of Nagpur fossil plantsf are unmistakably 

 of those species found also in the Raniganj coal-field, and whether fig. 3, 

 PI. XI, of Sir C. Bunbury's paper, be that of Fertebraria according to 

 McCoy and DeZigno or not, I do not think there can be a moment's doubt

 seams.
