the lower portion of the group ; it contains Alveolina, Nummulites spira, 

 N. obtusa, &c. The beds become nearly or quite vertical, and form a 

 steep ridge, succeeded to the westward by similar limestones dipping at a 

 moderate angle to the eastward. There is doubtless some faulting, but 

 the feature is a synclinal, more or less broken. In one of the limestone 

 beds dipping to the eastward, a little distance north-west of Bachani, 

 an oligurous crustaeean belonging to the genus Ranina was found. 



To the northward near Kajur, the faulting along the eastern edge 

 Fault east of Karnbu °^ the Kambu range is greater than at Bachani, 

 ran S e - and occurs apparently at the foot of the range 



between nummulitic limestone (Khirthar) and Manchhar beds. The 

 latter are seen dipping in the low ground towards the former ; the actual 

 contact is concealed by detritus, but the Khirthar beds first seen are 

 Alveolina limestones, probably far from the top of the group. 



Along the western side of the Kambu range the Nari beds are for 

 Beds to west of Kambu a long distance cut out by a fault, and Gaj beds 

 range> appear in contact with Khirthars, but towards 



the southern extremity of the range, as to the northward between the 

 Kambu and the termination of the Khirthar mountains, the Nari beds 

 appear in force. Indeed, the Kambu range appears approximately to 

 represent the eastern limit of the area of deposition in which the Nari 

 beds and all the lower Gaj beds were deposited, the only Gaj beds seen 

 to the eastward, in the valley between the Kambu and the Laki ranges, 

 and east of the latter, being apparently the uppermost layers of the 

 group. The Nari beds may of course have once existed to the eastward, 

 and have been removed by denudation, but in this case it is probable that 

 remains of them would be found here and there. 



It is difficult, however, to define the boundary between the Khirthar 



Kkirthari-Nari bound- and Nari beds in the southern portion of the 

 ary near Bbule Khan's 

 Tliana. Kambu range, and in the low anticlinal to the 



southward known as Gadula Hill, 2 or 3 miles north-west of Bhule Khan's 



Thana. In the latter hill especially, the uppermost bed, forming the 



greater part of the surface on the eastern side, is a whitish limestone
