 geology and fossils of the neighbourhood of Nagpur,f which he wrote 

 together with Mr. Hunter ; that on the connection of the Umr£t coalbeds 

 with the plantbeds of Nagpur,J and that on the age of the f ossiferous, thin- 

 bedded sandstones and coal of the province of Nagpur in India,§ which 

 was followed by a supplemental note in 1862. 



In a paper by Baron de Zigno, entitled " Observations on the Flora of 

 the Oolites," || he also makes general remarks on the Indian fossil Floras 

 placing them all with the Oolite formation. 



In the Proceedings of the Austrian Geological Institute (Verhandlun- 

 gen der k. k. Geologischen Beichsanstalt) for the year 1861-62, there is a 

 note upon the first 35 plates of the Eajmahal plants, which states, that 

 the figures of Zamites, Pterophyllum, Pecopteris, Taeniopteris etc., agree 

 with Austrian Keuper plants. 



In another paper entitled " Sopra depositi di piante fossili del America 

 settentrionale delle Inde e dell Australia, etc. " 1862, Baron de Zigno has 

 attributed a liassic age to the flora of the Eajmahal group. 



In the same year (1862) Professor E. Jones published his Monograph 

 of fossil Estheriae^]" wherein also the EstJieriae of the Indian Gondwana 

 system are described, especially JS. mangaliensis, Jon., which is so 

 abundant in the Mangli shales. 



Here I have also to mention Professor Morris as co-author of a work 

 on the Eajmahal Flora (1862) for although it was published in the Palseonto- 

 logia Indica, he was not connected with the Geological Survey. 



In 1864 a reptilian fossil, said to belong to the genus ArcTiegosaurus 

 was collected by Major Go wan near Bijori in the Satpura basin. ## 



Ettingshausen in his great work on the comparison of living with fos- 

 sil ferns,tt classes our Taeniopteris lata and T. morrisi (now Macro- 

 taeniopteris) from the Eajmahal group, with Acrostichum, and writes of 

 that formation as being liassic. 



I should also refer here to Professor Huxley's paper " on the vertebrate 

 fossils from the Panchet rocks near Eaniganj, Bengal, J J for although the
