throughout the length of the area described here ; in most cases the 

 lithological character of the beds composing these horizons remains 

 remarkably uniform. 



On the whole a great likeness exists between the trias and 

 rhaetic of the Himalayas and the Alpine type of these systems; a 

 feature which had long ago been recognised by Salter, 1 Strachey, 2 

 and Eduard Suess, 3 and enough fossils have been obtained from 

 the different divisions to enable us to compare the trias of the Hima- 

 layas with that of the Eastern Alps. 



I distinguished the following divisions and zones in the trias sec- 

 tions of the Himalayas.
