b WYNNE : TllANS-JNDUS EXTENSION OF THE PUNJAB SALT EANGE. 



Stoliczka and confirmed by himself from my discovery therein of Obolus 

 (see Salt Range Memoir, page 68), is bracketed together with the "pro- 

 ductus limestone," as well as the two unfossiliferous groups beneath this 

 limestone. 



In the footnote on page 3 of the paper under notice, it is said that 

 I considered Terebraiula (Waldhemia) flemingi to be carboniferous. This 

 is an error : the settlement of such a point I left of course to the 

 palaeontologists of the survey, whose proper business it was, but I have 

 pointed out the higher horizon at which the fossil was obtained on page 

 1 04 of my Report. 



In the recently published Manual of the Geological Survey, in the 

 Geological Survey Ma- Introduction as well as in chapters xx and xxi, 

 nual - there are numerous scattered allusions, both directly 



and indirectly bearing upon the geology of this district, chiefly taken 

 from pre-existing papers, but from want of correct observations on this 

 trans-Indus region the references to its physical geography are more 

 reliable than those to its geology. Regarding the latter, the reader will 

 not be able to gather much information, most of the points noticed 

 as taken from the accounts given by earlier observers sharing their 

 inaccuracy or inadequacy. 



The impression might be conveyed 1 that a distinct assemblage of 

 cretaceous rocks ranging from lower neocomian to the upper (?) horizon 

 of the olive group of the Salt Range, is present at Chichali pass. 

 At this place (see Salt Range Memoir, pages 105, 276, 277) one 

 thick dark-coloured bed forms the top of the Jurassic series, and in its 

 upper part an Ammonite occurs, which has been determined by 

 Dr. Waagen to be of neocomian age, while other Ammonites and JBelem- 

 nites in the lower part of the same bed are on the same authority said 

 to be Jurassic. This dark zone is overlaid by a thick light-coloured sand- 

 stone previously referred to the cretaceous period, but it has furnished 

 no fossils, and has been since found to occupy the same relative position
