sandy and obliquely laminated above. Upon these rest yellow marly 

 limestoneSj with Oysters, EcJdnanfkus, sp., Balanus sublavis, Natica, 

 Corallines, Cidaris sp. spines, ScJdzaster Belwchistanensis, EcJiinolampus 

 spheroidalis, and Yicaryi. 



Near Bitta this stream exposes some brown sands such as were 

 noticed at Teyrah and Nullia, and little else 

 besides superficial deposits is seen over these 

 plains. Towards Rowa, however, the ground rises slightly, and the 

 stream there shows a section in nearly horizontal beds, consisting of 

 brown sands and sandstones above and lumpy concretionary clay beds 

 among fine soft sandstones, beneath which a bright yellow claystone 

 occurs. No organisms whatever were found in these beds. 



The plain to the south of this shows an approach to the black soil 

 of Western India. 



Just south-west of Barachor the variegated soft rocks of the sub- 

 nummulitic group appear in a stream, resting 

 upon the traps, the upper flow of which is ferru- 

 ginous and vesicular, weathering greenish and powdery. The marbled 

 purple and white unctuous deposits above this have a thickness of 30 

 feet, are soft enough to be cut readily by a knife, and are traversed by 

 veins and strings of red haematite. Above these is a laterite bed, 

 blotched red and white, overlaid at a little distance by a band of frag- 

 mentary shell limestone, containing fossils similar to those found near 

 Wumootee. 



On the southern slopes of the hills north of Roha, much of the 



trap weathers to a brownish dry earth. Thick 



flows of soft splintery rotten' dark trap with 



concretions and lumps of harder nature overlie these, and at one place 



contain a (2-foot) bed of red bole, showing the dip plainly at 10° to 



S.25'=W.
