from the Raritan by an erosional unconformity. Its fauna has fur- 
nished but meager data for exact correlation but the large flora furnishes 
decisive evidence on this point. Compared with the underlying Rari- 
tan it may be noted that 61% of the Raritan flora becomes extinct be- 
fore Magothy time and 70% of the flora of the latter, including many 
new and progressive types, is not found at horizons as old as the Raritan.

loosa and lower Eutaw of the Eastern Gulf. 
Compared with European floras that of the Magothy shows several 
types identical with and many closely related to those of the lower basin 
of the Rhone, Bussaco, in Portugal, and the richly plant-bearing Turo- 
nian section of Bohemia. This floral similarity as well as the strati- 
graphic position of the Magothy leads to the conclusion that the Mago- 
thy formation is of Turonian age.
