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 wdth a wide 

 range. The present species, which ranges through the Green- 

 land Cretaceous series from the Kome 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 and Delaware; and it has recently been collected in the 

 Upper Cretaceous of the Western Interior. It is not contained 

 in any recent collections from the Raritan.

The presence of this species in New Jersey, like the preceding, 

 is based upon very fragmentary specimens. It is mucli larger 

 than the other Gleichenia-like fragments from the Raritan and 

 agrees closely with 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 Cre- 

 taceous of the Western United States.
