can, however, be but little doubt that the conglomerates are identical 

 with those of the Dhar forest, and there cannot be much doubt of their 

 identification with the similar beds at Lokurtullai, while the limestone 

 appears equally clearly to represent that of the EUichpoor beds and pro- 

 bably the uppermost Bagh beds. It should be added that similar lime- 

 stone occurs beneath the trap close to the smaller Tawa river about fifteen 

 miles east of Poonassa, and that the distance from Poonassa to Lokurtidlai 

 is about seventy miles, the whole intervening distance being occupied by 

 trap. 



Thus it will be seen that a connexion has been traced out between 



the sandstones of Bagh and the conglomerates of

the Puchmurry hills, and also between the marine 



limestone of Bagh and the freshwater limestone of the Lametas. 



Further researches may be necessary to establish this correlation, but it 



appears to rest on strong evidence. 



One circumstance should be borne in mind : The traps are represented 

 by Mr. J. G. Medlicott to be quite unconformable upon the Mahade- 

 vas. They appear, on the other hand, to be quite conformable to the 

 Lametas. To the Bagh beds they have been shown to be generally ap- 

 proximately conformable, but with marked local unconformity. It is 

 possible that the Lametas may be rather newer, or that the base of the 

 traps to the eastward may be rather older. But the greater unconform- 

 ity shown between the traps and the Mahadevas may be due to an 

 interval between them represented by the limestones of Bagh. 



It is also highly probable that the cherty masses so frequently
