cases, be made not only to their distance above the base of the series, 
but also to their distance from the Iraty black shale, which lies 
approximately 280 meters above the base of the series in the Minas 
district, and which Dr. White has been able fortunately to identify in 
the State of Rio Grande do Sul, as well as in Parana and Sao Paulo. 
The position of the plant beds in these states will be given, 
when possible, with réference to the Iraty black shale. For this very 
important stratigraphic information Iam indebted to the kindness of 
Dr. White, in whose epecial report will be found full stratigraphic 
details relaling tothe individual localities.
