4 HOLLAND AND TIPPER: INDIAN GEOLOC4ICAL TERMINOLOGY. 



queut observations, however, -have shown that the attempt was 

 very largely premature ; for Dr. Carter grouped together the 

 G-ondwanas with the much older Transition and Vindhyan systems, 

 increasing the prominence of the error by correlating all these sedi- 

 ments with the ' ' Oolitic ' ' series of Europe. He regarded the trap 

 sheets of the Bombay Presidency as intrusive, whereas subsequent 

 observers agree in considering these to be normal effusive lava- 

 flows. Although marked by errors of classification and correlation, 

 Dr. Carter accumulated a large quantity of valuable detail, both 

 palEeontological and stratigraphical. His classification of the Indian 

 formations is shown in the following table : —
