16 WYNNE; GEOLOGY OP THE SALT RANGE IN THE PUNJAB, 



and carbonaceous slates {6), Jurassic, succeeded by (7) nodular sandstone^ 

 and sbaley bituminous clay with lignite and limestone with NtimmuUtes 

 (8), shaley grey limestone with Nummulites (9), grey or yellowish lime- 

 stone marly or sandy and sub-compact, and (10) nodular sandstone, the 

 whole from No. 7 forming the lower tertiary sub-division^ overlaid by 

 (11) younger tertiary rocks with bones. 



In their palseontological resume, the authors refer to the Punjab as 

 their " second region " or province, the first being Sind, Beluchistan, and 

 Kach, and the third the Himalayan or Subathu division. Of the forty- 

 four Punjab (Salt Range) nummulitic species of fossils, they found 

 eighteen common to the first province, but none common to the Salt 

 Range and Subathu rocks. They appear not to have known any Salt 

 Range Ce^Jialo^oda, and of its Echinodermata mention only one species. 



The next account of the geology of the Salt Range is by Mr. 



Theobald,* who had, when exploring the range

with Dr. Fleming, good opportunities for studying 



the subject. The paper was written three years before it was published, 



but revised and curtailed owing to the publication of others on the same 



subject in England. The writer gives a close description of the physical 



features and general appearance of the range, its direction, length, and 



width, remarkable points and heights. 



Passing to the geology of the range, Mr. Theobald avoids discussing 

 the identity of the geological groups with similar ones in Europe, but 

 remarks that " it would not be difficult to identify almost every bed 

 of the permian and saliferous rocks of Europe by lithological character 

 with the beds of the Salt Range below the nummulitic limestone, but 

 in an inversed order." He contends that as the whole of the strata are 

 conformable they were deposited during subsidence, and he attributes 

 the formation of valleys on the plateau and gorges leading thence to the
