the Lower Gondwdna series, it represents in Indian geological homotaxis 

 the period of the Trias in Europe. He connects the Panchet with the 

 Raniganj flora through Schizoneura Gondwanensis, and this again with 

 that of the Barakar through the genus Glossopteris, while that of the 

 Talchir is united with that of the Barakar through Gangamqpteris 

 cyclopteroides. 



The Panchet group has always, since its fossils were determined, 

 been considered as probably Triassic, but the Raniganj, ironstone shales. 

 Barakar and Talchir groups have hitherto been thought to be possibly 

 older : the stratigraphical unconformity of the Panchets to the under- 

 lying Raniganj beds suggesting the view. The general facies, how- 

 ever, of the plant-remains of the Lower Gondwana series, Dr. Feistmantel 

 maintains to be Triassic, and not Palseozoic. In the absence, therefore, 

 of the more reliable data that would have been afforded by marine fossils 

 we may accept his conclusion, awarding such measure of value as an ad- 

 herence to the doctrine of "European affinity the test of age " may allow. 



Lameta group. — The identification of the Lame'ta group rests upon 

 the recognition of limestone resembling that which is supposed to be 

 the typical rock near Jabalpur, and also upon the similarity of fossil 

 remains. The synonymous term for Lameta given by Mr. Blanford — 

 " Infra-trappean" — expresses its relationship to the trap ; and that it is 

 closely connected with that series is shewn by its mode of occurrence 

 (the outlines of its outcrops conforming in a noticeable manner to those 

 of the trap), and by the discovery of a fossiliferous band underlying the 

 Dhamni fish-beds that contained the characteristic Unios of the inter- 

 trappean series.
