ing fossils. These form the scarp to the eastward, which is 200 to 300 



feet in height. 



The coal or lignite bed of Lainyan (Leilan) was discovered amongst 



Coal or lignite of Lain- tne sand J snales and cla y s in a wel1 sunk b y the 

 y an * Baluch nomads who inhabit the country, and when 



found was said to be 7 feet thick. This is doubtful, but the seam 



measured nearly 6 feet in places. A second smaller seam was found 



beneath the thicker bed. The coal, however, was found to thin out 



within a short distance, nowhere exceeding 100 yards. The quality too 



was inferior. 



The best section of the fossiliferous limestones, overlying the shales 



and sandstones of the Ranikot group, is seen in the 

 Section of fossiliferous . 



beds at top of Ranikot scarp to the eastward or Lamyan. 1 hese lime- 



group ' stones are the beds the absence of which in the 



sections of the Laki range has already been noticed. 1 The whole of 



these brown limestones and their associated beds, east of Lainyan, are 



considered by Mr. Fedden to be not less than 800 feet in thickness ; but 



the highest portion is not seen in the scarp section. 



The uppermost bed seen in the scarp is rather hard, massive, and of great 

 thickness. It is a brown limestone containing numerous fossils, amongst 

 which are a large Nautilus, Sftondyhis rouaulti, a Terebraiula closely allied 

 to the cretaceous T. subrotunda, a Conoclypeus, and several corals, including 

 TrocJwcyaiJius vandenhecJcei, Cyclolites vicaryi, and Montlivaultia jacquemonti. 

 Below this bed are some clays and ferruginous shales. Then follows in 

 descending order another limestone bed, about 30 feet thick. This 

 abounds in Ostrea vesicularis and Ttmitella, and contains Vulsella legumen, 

 in masses, several individuals cemented together, a flat Uc/miolamjms, 

 and Opercidina. Below this bed again is greyish-brown sandstone, with 

 one or more bands of limestone, and then the variegated sands, shales, 

 and clays.
