" The finest sections are exposed in the Khirthar range in Upper Sind, and from this 

 range the name applied to the Nummulitic limestone, which always forms the highest 

 part of the hills, has been taken. On the eastern flank of the range, the Nari, Gaj, 

 and Manchhar beds are seen successively dipping towards the Indus plain, whilst west 

 of the range, in Kelat, lower beds come in ; but these have hitherto only been examined 

 very hurriedly in one spot, on the Gaj river, which traverses the main range by an im- 

 passable gorge. Some 10,000 feet of these lower beds are exposed, no base being seen ; 

 but Nummulitic and other fossils were only found in the higher beds, the lower 5000 

 or 6000 feet being unfossiliferous. 



" The only other place in Sind where beds inferior to the Nummulitic limestone were 

 found to be exposed is in the nameless range of hills running south from Sehwan. This 

 range is sometimes spoken of as the Laki range, from the village of Laki near the nor- 

 thern extremity. It appears to be part of the Hala range of Vicary and others ; but the 

 Hala range of the old maps included the Khirthar and several other ranges, and no 

 distinct chain of hills is known by any such name in the country. There is, however, 

 an unimportant pass in the Laki range known as Hala Lak (Lak=pass). Each sepa- 

 rate peak of this range has its own name, no general term being applied to the whole.
