The higher portion of the Brazilian series, including the Iraty 
black shale and the overlying 150 meters or more of red and grey 
beds, etc., with Lycopodiopsis Derbyi, Sigillaria (?) muralis, Dado- 
aylon (2), and Psaronius, is to be regarded as corresponding in age 
to a portion, at least, of the Damuda series in India. I confidently 
expect that subsequent studies of these beds, which are at present 
little known paleobotanically, will fully confirm this somewhat 
tentative correlation. 
In Australia and South Africa it is clear that our flora finds its 
close identities in the Newcastle series of New South Wales, the Bowen 
River series in Qaeensland, the Mersey series of Tasmania, and in the 
Ecca shales and Beaufort series in the Transvaal, Cape Colony, Natal, 
Orange River Colony, and German East Africa. Beds of the same age 
in Argentina are recognized by Bodenbender and Kurtz in the precor- 
dilleras and in the Pampean sierras in the provinces of San Juan, La 
Rioja, San Luis and Mendoza. 
The general systematic positions of these formations is indicated 
in a very broad way in the accompanying table compiled from various 
sources. 
The tabulation of the Mesozoic formations is given to show the 
sequence, rather than to indicate the contemporaneity of the beds 
placed at the same level. For discussions of the equivalences of the 
series see F'rech: Lethaea Geognostica, vol. II pt. 4, 1902, pp. 579-623 ;
