Brought forward 

 24. Shaly calcareous sandstone .... 



23. Crinoid limestone with a shaly parting 

 22. „ i) with Pecten bifrons Salt 



Lower 2T. Dark limestone alternating with shaly Crinoid beds 

 Rbsetic. 20. Dark-grey limestone, dolomitic, with shaly partings 

 19. Dark fossiliferous Crinoid limestone in massive beds 

 18. Grey earthy limestone with numerous Myacites sp. 

 17. Hard limestone beds, containing many fossils, and on the wea 



thered surfaces showing sections of large Megalodon sp. 

 16. Hard Crinoid limestone in thick beds 

 15. Dolomitic limestone ...... 



14. „ „ in flaggy beds .... 



13. Massive grey dolomite, towards base rather flaggy 

 12. Massive dolomite, with scarcely any bedding visible 

 1 1. Massive beds of dark grey dolomite with partings of Crinoid 

 limestone .......•• 



10 Dolomite in beds of about 4 feet thickness, reddish near base 

 and containing Lithodendron . . . . . 



9. Dark concretionary limestone changing laterally into cellular 

 Rauchwacke, of reddish purple colour; in beds of 6 inches 

 to 1 foot ......... 



Crinoid limestone in thick beds » . . . 



Dark dolomites in massive beds, the contact surfaces knitted 



together, resembling sutures in the outcrop 

 Dolomite and limestone beds, with " knitted " contact surfaces 

 full of "Lithodendron and with a few shaly partings . 

 ;. Massive beds of dark blue limestone and dolomite alternating 

 with flaggy beds of limestone ; the latter form about 12 feet 

 of the upper part of this sub-division ; some of the beds 

 contain masses of dark purple colour with Crinoids 

 Dark dolomite beds with calcspar veins, thick bedded . 

 Same as 4, but beds are flaggy and have shaly sandstone part- 

 ings ..... • 



Dark hard concretionary limestone, alternating with dolomitic 

 beds .......... 



Grey and reddish dolomites, forming perfectly inaccessible 

 cliffs . . . . . . . . about

This continuous sequence of beds can only be roughly sub-divided 

 into divisions ; but although the beds all seem to pass gradually from one 

 into the other it is not difficult to observe that great differences exist 

 in lithological character of the strata which form this section, as in- 

 deed is the case in all the other rhsetic localities in the Central Him£-
