•material goes it corresponds exactly with the more typical
material from other regions, and until specimens are collected
showing adequate grounds for separation, we are justified in
assuming the.presence of this species in New Jersey in Raritan
times. The genus Gleichenia was a prominent one during the
Cretaceous with many.characteristic species, some with a wide
range. The present species, which ranges through the Greenland
Cretaceous series from the Kolne beds to those of Patoot,
occurs also in the Lower Cretaceous of Spitzbergen and the
Black "Hills; the Cenomanian of Bohemia; the Senonian of
Bohemia, Saxony and Bulgaria; the Magothy formation of New
Jersey andDelaware; and it has recently been collected in the
Upper Cretaceous of the Western Interior. It is not contained
in any recent collections from the Rat:tan.

The presence of this species in New Jersey. like the preceding,
is based upon very fragTnentary specimens. It is much larger
than the other Gleichenia-like fragments from the Rat:tan and
agrees closely w'ith Heer's species which ranged through the
Greenland Cretaceous occurring in the Kome, Atane and Patoot
beds. It has also been collected recently from the Upper Cretaceous
of the Western United States.
