Correlations with India. 



Tschernyschew regards it as " highly desirable to discuss in 

 detail the section of the Salt Range, which, as far as the sequence 

 of the horizons and their paleontological characteristics are 

 concerned, is described more completely than is any other 

 region of Asia. This area is at present not only the starting- 

 point for the correlation of other Asiatic regions, but for the 

 Austrian Paleozoic as well ; hence I hold that my v iew regard- 

 ing this profile will not be unacceptable" (p. 715).
