lower in the series than the shales just mentioned, but the section is not 

 clear. Farther to the westward are black hillocks, composed of soft disin- 

 tegrated shale, with large ferruginous concretions, and covered over with 

 fragments of black highly ferruginous sandstone forming a gravel. No 

 good section is seen, nor were any fossils found. These beds are, how- 

 ever, higher than those seen near the road. 



Still higher in this section ferruginous black sandstone is found in 

 place, the upper portion passing into richly ferruginous clay, in part red 

 haematite, succeeded in ascending order by a few feet of crumbling 

 mottled clay impregnated with salt. Then comes a light-coloured 

 yellowish earthy marl, with Alveolina, Orbitolites, and a few nummulites. 

 This passes up into sandy and then into calcareous beds with Alveolina. 

 The last are considered the base of the Khirthar group. 



The Khirthar limestone, along the scarp of Aongar Hill, above the 

 rocks just described, appears to be thinly bedded and weathers into flags. 

 Much flint derived from the limestone is scattered about. There are 

 numerous small outliers of Khirthar limestone on the Ranikot area, but 

 they are of no importance, and the details of the topography on the map 

 are not accurate enough to enable small patches to be correctly laid down 

 without much difficulty and loss of time. 



Farther to the westward, below the base of the Khirthar group, a well 

 marked lateritic bed comes in, composed in large measure of red ironstone 

 (apparently a mixture of red and brown haematite). The underlying 

 Ranikot beds are of very loose and incoherent materials. The ferrugin- 

 ous band corresponds in position with that near Bandh Vera and Lainyan. 

 Still farther west highly calcareous sandstone comes in between the white 

 Khirthar limestone and the Ranikot group ; this sandstone is of a light 

 yellowish-brown colour, and forms a conspicuous band on the slope of the 

 hill. A few fragmentary Foraminifera and a small Brissopsis occur in 

 this bed. In this ground there are one or two sharp folds of the rocks. 



Still farther west, near Meting station on the railway, the brown 



Near Meting Railway calcareous sandstone, here so calcareous as to be a 



stutlo)1 - sandy limestone, increases in thickness and im-
