THE LARI RANGE, ETC. 133 



On the top of the hills is a bed containing- oysters and fragments of 

 large bones, apparently reptilian. West of the hills the olive shales with 

 Cardita leatmionti occur in a marked depression, due to the weathering 

 of these soft beds, which dip westward at a much higher angle than the 

 sandstones, the latter rolling over to the eastward with the usual ten- 

 dency to an anticlinal. In the olive shales at this spot, besides the usual 

 fossils, two or three fragmentary amphiccelous reptilian vertebra? were 

 obtained, since identified by Mr. Lydekker as belonging to a mesozoic 

 type of crocodiles. Above the olive shales, the trap is found in the usual 

 position, and the Ranikot group, here of great thickness, is exposed on 

 the slopes of the main range and capped by the Khirthar limestone. 



This, as already stated, is the only place where the white limestone

ceous sandstone. South of Barrah Hill the main 



fault appears to divide, and a branch running- to the south-west, and 



having a downthrow to the south-east, causes the disappearance of all 



the cretaceous rocks below the Cardita beaumonti beds, and brings in 



Ranikot beds west of the main fault. For some distance south of the 



branch fault, the olive shales with Cardita beaumonti form an anticlinal, 



and their outcrop is scarcely a quarter of a mile broad, the trap bed 



resting upon them, and the Ranikot group upon the trap, both east and 



west of the anticlinal. This, however, only continues for about a mile, 



then the cretaceous strata suddenly roll up to the southward, the Ranikot 



beds to the east of the anticlinal come to an end, and the cretaceous 



sandstones re-appear and form the high dark-coloured hill of Bor. 1

lowest beds seen are the cretaceous sandstones. The Manchhar beds are 



highly inclined, and dip at about 75° to east-10°-north; the Khirthars 



1 The section at Bor Hill was examined by Mr. Fedden only, and I unfortunately mis- 

 understood his account of the section, and, consequently, omitted to search for the lower 

 bed of trap when I made a rather hurried examination of the hills in 1877.
