where Dr. Ramiro Barcellos has explored the measures :

lt is quite probable that ns. 8, 9 and 10 represent the S. Jeronymo 
coal bed, with the parting clay greatly increased in thickness and 
they are also doubtless identical with the Barro Branco bed of Santa 
Catharina. From n. 13 were collected some fossil plants among 
which Dr. David White has listed the following species as coming 
at the horizon of the Jrapudé coal, the designation of n. 14 : Glos- 
sopteris Indica, Glossopteris Browniana, Cardiocarpon Barcellosum 
Ottokaria ovaris, etc. 
Another partial section of Rio Bonito beds about 400 kilometers 
southwest from Irapud, near Candiota in Rio Grande do Sul, will 
show the persistency of the S. Jeronymo coal. This section was 
measured at Serro Partido, on the fazenda of Cor. Manoel Lucas 
de Lima which occupies the region between Rio Candiota and Rio 
Tigre. It reads as follows in descending order :
