ADIGRAT SANDSTONES. 1 75 



It is possible that the beds associated with coal in the 

 Chelga district may be of the same age as the Adigrat 

 sandstone. It is very much to be regretted that the 

 problem of their age, one of the most interesting geo- 

 logical questions in Abyssinia, could not be solved.^ 



1 I -would venture to suggest the possibility that both the coal-bearing beds 

 of Chelga and the Adigrat sandstones may belong to a portion of the great 

 series associated with coal in India — the Damudas and their associates of the 

 Indian Survey classification. This, of course, is mere surmise, and my only 

 reason for thinking it probable is the resemblance between the fossils of the 

 dicynodont beds of South Africa and the Panchets of India, and the want, so 

 far as is known, in Equatorial and Southern Africa, as in great part of 

 Southern Asia, of marine representatives of the upper palaeozoics and lower 

 mesozoics of Europe.
