miles, and the average dip at 20° (probably rather too low), the thickness 

 of the Nari group must be over 5,000 feet. 



The rocks in the plain west of Mol plateau, between the latter and 

 the Hamlig range, consist also of Nari beds, but with an eastwardly dip, 

 the Mol plateau being in the middle of a synclinal fold. In the north- 

 ern part of the plain the Nari beds are nearly horizontal, except in 

 the neighbourhood of the Hamlig range, where they turn up and dip 

 sharply to the east. In the southern part of the plain the dip is 

 generally south-east. 



The Hamlig Hills extend for many miles from north to south, along 



the left or eastern bank of the Habb river, from 

 Hamlig Hills. ^^ ^ g £, ^ ^^ ggo gg, north latitude _ 



They are entirely outside the British frontier, and they were only exa- 

 mined very cursorily at their southern extremity near Kand. Here 

 they appear to consist of beds shown to belong to the Khirthar group 

 by their fossils, but differing entirely from the usual type of beds belong- 

 ing to that formation in Sind, all massive limestones being completely 

 absent. The prevailing beds are fine sandstones of various colours, 

 white, cream-coloured, brown, and olive, and thick olive or grey shales, 

 breaking up when exposed into minute fragments, with thin bands of 

 harder bright rufous brown shale interstratified. Many of the sand- 

 stones also are shaly and thinly bedded, with peculiar salient and angular 

 markings on the surface of the beds. These rocks resemble the beds 

 below the massive Khirthar limestone on the Gaj river ; and they also 

 closely coincide in character with those attributed to the eocene forma- 

 tion in Makran (Southern Baluchistan), north of Gwadar. 



There is no marked break between the Nari and Khirthar beds. 

 A bed with an Orbit oides, apparently undistinguishable from 0. 

 papyracea, occurs some distance below the top of the shales, so these 

 may be Nari, in part at all events. Some distance lower down a 

 calcareous grit is exposed, containing typical Khirthar nummulites, such 

 as N. spira, 2V. granulosa, N. ohtusa, N. scabra ?, &c, and with these 

 is a saddle-shaped Orbitoides, apparently 0. dispansa. Beneath this grit
