KAMET AND SP1T1. 207 



or else he would not have fallen partly into the same errors Stoliczka 

 committed on his first visit to that valley. Oldham gave the results of 

 his reconnaissances in two papers 1 ; subsequently I gave an outline 

 of my own observations on the Spiti sections in a short paper. 2 



I have already given the sequence of formations in Spiti, accord- 

 ing to Stoliczka, but it will be convenient to re- 



Stoliczka's sequence. 



capitulate the list. 



He grouped the sedimentary formations below the Jurassic "Spiti " 



shales into the following divisions: — 



Upper Tagling ........ Lias.

Trias. — I have little to say concerning the mesozoic rocks; of 

 Spiti the general grouping as shown by Stoliczka is according to 

 facts, and I have only to add that the trias (Muschelkalk horizon) 

 does not rest directly upon carboniferous; but there is a series of beds, 

 underlying the former conformably, ranging through the upper Pro- 

 ductus shales (permian), the Otoceras (passage) beds and thin lime- 

 stones with lower trias Brachiopods, which series comprises the lowest 

 trias (Bunter) of Central Europe, but reaching down even to the 

 upper permian. This series is not of great thickness, but is well 

 exposed both at Muth, and in sections north of it (Kuling, &c), but 

 Stoliczka has apparently included it in the Ruling beds. 



The chief changes which should now be made in the correlation 

 and nomenclature of the Spiti formations concern the palaeozoic 

 group, but I shall give a summary of the points on which I differ 

 chiefly with Stoliczka, at the end of this chapter. 



I entered the Spiti drainage by the Babeh Pass (fig. 30^, returning
