Khyrabad hills. 



On tlie western side of the hills here, particularly along the Barki 

 nulla, there is a thick deposit of rubbly stream- 

 like conglomerate and clay, forming cliffs 200 

 feet high, the fragments being of the local rocks. A couple of 

 small mound-like hills near Khyrabad are formed by brecciated (and 

 magnesian ?) limestone, with some sandstone and shales of the 

 Jurassic group, indicating the direction in which these rocks pass 

 into the plains. The mass of the hills here is cut off from those towards 

 Mari, by the open valley of a nameless river coming from behind the 

 hills towards J aba. On the south-eastern side of this gap the massive, 

 thin-bedded, and lumpy layers of the nummulitic limestone are seen 

 to dip pretty steadily towards the east-north-east at 30°, underneath 

 heavy masses of light, drab-coloured, gypseous clay, which lie along the
