2. — The northern watershed of the Teeree Towey (Tiri Taui) basin 

 and hills from Murdan Kh4l eastward by Weejoosum {Wtyu- 

 sum) and Drubbokus nearly to the Indus. 



The nummulitic limestone as usual forms the high ground overlook- 

 ing the (Tiri) valley near the Murdan Khel : yet

difier much from that last given; a singular 



T-shaped glen, opening through a rocky gorge southwards into the larger 

 valley near that village, having been eroded from a soft clayey and 

 sandstone group in the nummulitic rocks unseen before and which pre- 

 dominates in this vicinity. 



Besides the occurrence of different rocks, the usual amount of mis- 

 inversion : Murdan representation prevails in consequence of the inver- 

 Khe1, sion of the beds, a feature strongly developed here. 



Here, too, a band of rocks so identical with the lower tertiary sand- 

 stones as to be undistinguishable appears with all the aspect of intercala- 

 tion between the nummulitic limestones, and follows their outcrop, divi- 

 ding one band of these limestones from another. 



In the gorge near Murdan Khel the arrangement shown in Fig. 5 

 may be observed — 



Beds inverted. 



8. Purple and gray sandstones and purple clays at mouth of the gorge dipping 

 northward at 30°, and upwards, tertiary sandstones. 



7. Thick Alveolina limestones dipping north at 55°. 



6. Thinner and darker coloured limestone, nummulitic. 



5. Bluish-gray coarse sandstone and purple clays identical in character with those 

 of the lower tertiary sandstones, 



4. Limestone thinner hedded than 6 and 7, darker and more shaly. 



3. Lumpy, dark-coloured limestone with beds of platy shale. 



In these a band of coarse light purple conglomeratic sandstone 

 occurs, apparently overlying which only odd beds of limestone occur here 

 and there in sandstones often conglomeratic with pebbles of limestone 

 and crystalline rocks. The limestone bands contain both Ntmimulites and
