The remainder of the open country in this neighborhood is formed 

 of the upper Jurassic rocks^ with a few isolated

patches of the red volcanic rocks. Further to 

 the northward it becomes low, alluvial, or of the barren Runn-like 

 variety called Laana, and passes so gradually into the Bunnee and 

 Eunn that nothing like a line of demarkation exists. One slight 

 depression of the surface north of Damurka is a constantly wet jheel." 



' Rig her Tertiary' 1 — South and south-west of the range extends 

 „, . ,, ^ „ a broad plain at a slightly higher level than the 



Plain south of the ^ o j o 



l"ll8- alluvium that borders it on the south. In this 



plain some beds of cemented rock are occasionally seen cropping out 

 here and there and in the sloping sides of water-courses, resting hori- 

 zontally upon argillaceous and earthy reddish-brown deposits. These 

 are probably referable to some of the higher members of the tertiary 

 group. 



The cemented rock presents different appearances in different places ; 

 it generally assumes the form of a conglomerate with a kind of pisolitle 

 structure, made up of little nodules of kunkur. Some of these beds 

 are worked between Pussoora and Chiree for building materials, a 

 thickness of 10 to 14 feet being exposed, and among them are some 

 bands of fine micaceous silty clay. 



The pisolitic bed becomes more of a conglomerate or concrete in 

 another place where Balani were found attached to and imbedded in the 

 rock. A tough dark clay occurs below the Balanus conglomerate. 



In a conglomeritie concrete, 4 or 5 feet thick, associated with fine 



grained obliquely laminated sandstone, occurring

at the stream bank north of Pussoora, many 



small fragments of bone were found, also teeth and dermal plates, pro- 

 bably reptilian.
