and presents the same beds full of the gregarious fossil Spirifera trigona- 

 lis (?) and of Productus Costatus : the distance between these beds is the 

 same as it is at Barus. On the top of the Zeeawan beds are seen 

 Weean beds, but they are much more complete than at Barus, having 

 a thickness, from the top of the Zeeawan bed to the foot of the knoll, 

 of about 660 feet. But I believe there are probably some faults 

 which cause beds to be repeated, and that the Weean bed is not quite 

 so thick ; about 500 feet. 



The Pampur knoll gives the following approximate section fiom 

 east to west. 



1. Coarse grey limestone. 



2. Slaty grey limestone. 



3. Patchy blue and yellow or pale brown limestone. 



4. Compact blue limestone, argillaceous. 



5. Patchy blue and dirty yellow. 



These beds are together about 100 feet thick. They dip W. with an angle 

 of 60°. 



6. Flesh-coloured limestone, 



7. Shaly coarse blue limestone. 



8. Flesh-coloured limestone. 



. These 3 beds are together about 80 feet. Dip as above. 



Other layers are buried under lacustrine deposits. This little 

 hillock was examined very superficially, owing to want of time. No 

 i fossils were seen except the small broken bivalves mentioned above, 

 and which are so common in all the rocks of the Weean group. 



40. The spur seen half way between the Pampur knoll and 

 Reechpoora, is tipped with Zeeawan limestone, but was not examined 

 in detail. 



41. Here ends our survey of the Wastarwan. I need not say 

 that the central ridges and summits are entirely composed of volcanic 

 accumulations. Black basaltic rocks are abundant, and by their 

 disintegration, and the rearrangement by water of the black mud 

 they gave in decaying, a great quantity of black slate was formed 

 which is seen interbedded with beds of ash and agglomerate. These 

 volcanic rocks do not require to be described, as they are identical with 

 those of the Zebanwan Mountain, All the rocks of the Wastarwan 

 present a stratification or superposition; on the northern slope it
