78 WYNNE : TRANS-INDUS EXTENSION OE THE PUNJAB SALT RANGE. 



The Jurassic limestones mantle round, enfold, and occupy the whole of 



the anticlinal ellipsoid forming 1 the northern lobe

of Shekh Budfn. They are in places fossiliferous* 



and a considerable collection from these beds is in the hands of Dr. 



Waagen for determination. Among the highest, or forming the 



very highest layer around the ellipsoid, as well as overlying it in 



scattered patches to the east, near a tank on the descent from the 



summit towards Paniala, and again near the Pezu road, between the 



Giind and a summit called Pic-nic hill, there occurs a tough blackish 



sandy and ferruginous band of 40 to 50 feet or 

 Blackish zone. . 



less. This is almost exactly similar to the black 



band in the Chichali range on the same horizon containing uncanaliculate 



Belemnites and a neocomian Ammonite in its upper part, but enclosing* 



Jurassic Ammonites and Belemnites just beneath. 



This black band here (if it be quite the same) always contains Belem- 

 nites with and without canals. Ammonites of two or three species have 

 been found in it, but none that have been as yet identified with the 

 neocomian A. {PerispJiinctes) asterianus of Chichali pass : several fossils 

 besides, such as RhgncJwnella, Pecten, Qoniomya, Corals, Ostrea, &c, occur, 

 also nodular masses of hard clay full of cavities, apparently made by 

 boring shells. 



Not far below this horizon is a band of blue oolite which contains 

 numerous Betzice? some Pleurotomarice, and numbers of IP/wladomya, as 

 well as fragmentary Ammonites, &c. One always singularly well preserved 

 tumid Pecten ranges from these upper beds down into the variegated 

 series of the Paniala bluffs. The zone is perhaps partly representative 

 of some of the golden oolite layers elsewhere. 



In some spots, but always isolated, dislocated, or generally without 



any overlying strata, I have observed exposures of 



similar dark-coloured rocks to those just described, 



but not always found them to contain fossils. It is uncertain whether 



these exposures belong to the topmost Jurassic horizon, or may be those 



of other black bands at no great distance downwards in the series. The
