SOUTHERN KHIRTHAR, BHIT AND BADHRA RANGES. 117 



farther south, to the westward. South of Jhangar the greater part of the 



country for many miles is covered by alluvium, or by subrecent gravels 



and conglomerates. Beneath these deposits, the Manchhar and Gaj beds 



disappear on the western side of the valley, but the Manchhars come 



in again on the eastern side, where the Gaj group is either wanting or 



represented by a very thin band. A few miles south by west of 



Jhangar some soft sandstones and shaly clays, with bands of white clay, 



are seen in ravines, but it is difficult to determine with certainty to what 



group they belong. Anticlinal rolls of Khirthar limestone, forming low 



hills, crop out from beneath the Nari beds forming the middle of the 



valley further south. One small ridge of Khirthar beds occurs 7 miles 



south of Jhangar ; another, and much longer ridge, the Lunda hill, close 



to the camping ground of Chorlo (Choterah of 

 Lunda hill. . . . 



inch and ^-inch maps) , is formed by a double roll, a 

 slight synclinal on the top, with an anticlinal on each side, the outer 

 slopes being very steep. The brown limestones at the base of the Nari 

 beds are seen on the outer slopes of these hills, running up the hill- sides 

 as usual ; and near the base of the Nari group, there appears here a band 

 of brown limestone, containing in abundance a very large EcMnolamjpas, 

 apparently unnamed, having some resemblance in general form to the 

 Khirthar species, E. discoideus. The junction of the Khirthar and Nari 

 Junction of Nari and ^ e( ^ s * s particularly well seen near the Chorlo 

 Khirthar. encamping ground on the western flank of Lunda 



hill. Brown limestones, as usual, rest upon white ; the uppermost 

 white bed is rather saccharoid, and contains Hchinolampas discoideus, 

 Kuphus in abundance, conspicuous on account of its fragments consisting 

 of tubes about half an inch in diameter, an Orhitoides, and several species 

 of Nummulites. Upon this rests a hard compact ochrey or yellowish 

 brown limestone ringing under the hammer, breaking with a sharp 

 conchoidal fracture, and containing several nummulites and an Orhitoides 

 (0. dispansa ? ). This bed, despite its colour, appears to belong to the 

 Khirthar group. Above this again come the usual Nari brown limestones, 

 with Nummulites garansensis, N. suhlcevigata, and Orhitoides papyracea.
