sary to lay special stress on this fact, because Noetling in his historical 
retrospect ' somewhat exaggerates the importance of Stoliczka's work in 
Spiti affirming with great confidence that the only progress in the 
stratigraphy of the Trias since Stoliczka's memoir is marked by the 
discovery of the Lower Trias within the Lilang series. 
Stoliczka was particularly unfortunate in confining his attention 
to the Ruling section, which he presumably accepted as a typical one, 
whereas subsequent researches have shown the Lower Trias to be cut 
out there by a fault, which causes the Daonella shales to lie directly on 
the Productus shales. We may, however, admit that his overlooking 
the Lower Trias is easily explained by his short visit to the Spiti sec- 
tions and that his correlation of the entire Lilang series with the Upper 
Trias is pardonable, fossils of the Muschelkalk having been found, but 
not recognised as such before Stoliczka's survey began. 
There is, however, no doubt that considering the circumstances 
under which he worked, Stoliczka's stratigraphical results were most 
valuable. To him belongs the credit of having been the true pioneer of 
Himalayan stratigraphy. 
Very considerable progress was subsequently made by C. L. Griesbach, 
who succeeded Stoliczka in the geological exploration of the Himalayas 
and in 1880 gave the first systematic account of the Triassic system.'^ 
All subsequent accounts of the Himalayan Trias must needs be based 
on his work. 
He was the first to discover the Lower Trias and the Muschelkalk 
in situ. In a preliminary note on his first season's work in the Hima- 
layas he gave a detailed description of the section of the Shalshal cliff 
near Rimkin Paiar, in Painkhanda, together with description and 
figures of the fossils characteristic of the Oioceras horizon, which was 
then considered by him as a passage bed between the Permian and 
Triassic systems."' In the Upper Trias he distinguished a number of 
subdivisions, which still remain unaltered, although the knowledge of 
their fossils has led to a correlation with Alpine Triassic stages, differing 
widely from that which had been established by Griesbach.
