should be considered as representing the conglomerates of the upper 



Taptee valley. Very possibly some of the beds to the north of the Taptee 



should also be referred to the same series as the Glossopteris beds of Nagpoor. 



This is especially the case with the beds seen in the valley near Khattapani, 



the great vertical extent and disturbance exliibited by which and their 



apparent unconformity to the traps were noted at the time of the survey 



as showing them to be probably different from the usual infra-trappean 



sandstones and conglomerates. These latter from a thin band, rarely, if 



ever, exceeding 100 feet at the base of the traps, which appear to rest quite 



conformably upon them. 



Another connexion which has been traced out during the examination

and Bagli beds. h^^Q of Jubbulpoor and these sub-trappean rocks. 



The Lameta beds* chiefly consist of — 



1. Gritty and cherty limestone ; 



2. Nodular limestone ; 



3. Loosely aggi'egated greenish sandstone ; 



4. Argillaceous beds, purplisli or greenish, arenaceous or marly ; 

 the gritty and cherty limestone being by far the most typical and 

 widely spread member of the group. This has been traced at intervals 

 from Jubbulpoor to considerably south of Nagpoor, and there can be 

 scarcely a doubt that it is identical with the subtrappean limestone of 

 Ellichpoor. A bed which cannot be distinguished from it mineralogically 

 is also met with frequently, interstratified with the traps, between 

 Jubbulpoor and Nagpoor and in the neighbourhood of the latter. 



This is not the only point of connexion of the Lametas with the 

 Bagh beds. The nodular earthy limestone at Lameta ghat which there 

 underlies the gritty and cherty limestone is very similar in appearance 

 to the nodular limestone of Bagh and Cherakhan. Sandstone in both 

 cases when present appears to be a lower formation in the same group.f
