PL ANT-BE AKIKG SERIES OF INDIA. 523 



The plant-remains obtained from the Kamthi group by Mr. Hislop 

 have been figured and described by Sir Charles Bunbury*, who 

 identified the most abundant fossil as Glossopteris Browniana, iden- 

 tical with that of the Biniganj group of Bengal. The Vertebraria 

 {V. indica) and the Phylloiheca (P. indica) are also identical f. But 

 other characteristic plants of the latter formation, viz. SpJienophyl- 

 lum (Trizygia) and JSchizoneura (Zeugophyllites) are absent £. On 

 these grounds, as well as on that of their position, Mr. W. T. Blan- 

 ford regards the Kamthis either as the Central-Indian representa- 

 tives of the Baniganj group of Bengal, or as intermediate between 

 this and the Panchets. The beds at Mangli, in which Mr. Hislop 

 found Brachyops laticeps, Owen, and Estlieria mangaliensis, Jones, 

 with the teeth and scales of Ganoid fishes, are considered by Mr. 

 Blanford to be the upper beds of this group ; and E. mangaliensis has 

 been identified, though doubtfully, with the species occurring in the 

 Panchets of Bengal, in which also occur Labyrinthodont remains &c. 

 On these grounds, and partly on that of the greater lithological 

 resemblance of the Kamthi to the Panchets, Dr. Oldham considers § 

 these two groups to be more nearly related to each other than to the 

 Biniganj group of Bengal. 



The beds of Maledi, however, which overlie the Kamthis, are re- 

 garded by both as Panchets. In these occur Ceratodus || and Hype- 

 rodapedon%, both Triassic genera in Europe, though it must not 

 be forgotten that two species of the former are now living in 

 Australia **. 



The geology of the Godavery valley has not yet been worked out 

 in detail ; but the officers of the Geological Survey are, I believe, 

 agreed in regarding the Kota beds, in which were found the remains 

 of Lepidotus and^Eb7imo<iwstf, as probably more recent than any of 

 the above. 



Y. Representatives of the Rajmahal group have only lately been 

 met with J J in the Godavery basins ; and no description of them has 

 yet been published ; but plant-beds containing Palceozamicu, some of 

 which Dr. Oldham §§ has identified with Cutch species, occur in Tri- 

 chinopoly||jj, underlying the cretaceous rocks of that district, and also 

 covering a large area of the plains of the Payen Ghat, west of 

 Madras ^[if. In the former region they have afforded no marine 

 fossils; but they appeared to me***, both on stratigraphical and 

 lithological grounds, to be not very widely separated in time from the 

 cretaceous rocks immediately overlying them (the Ootatoor group),
