 be of specific value. It is to be hoped that additional and more 

 representative material may eventually be collected.

Description. — ^Judging from Corda's original drawing, which 

 is preserved in the library of the N. Y. Botanical Garden, and 

 from the numerous figures published by Velenovsky, the Euro- 

 pean specimens, which come from several Cretaceous localities in 

 Bohemia (Lann, Vyserovic, Weissenberg, etc.), are correctly 

 identified as cycadaceous fructifications. With regard to New- 

 berry's specimens no such certainty can be entertained. The type 

 material cannot be found at the N. Y. Botanical Garden, and what 

 specimens of this species are in the collections of that institution 

 are in a very poor state of preservation. Newberry's figures are 

 only remotely like those of the European material, and his deter- 

 mination must be considered very doubtful, although there are 

 no apriori reasons why this form should not occur in the Raritan, 

 since cycad foliage is rather common, and the New Jersey and 

 Bohemian Cretaceous have quite a number of identical species. 



A fact tending to throw still more doubt on Newberry's iden- 

 fication was observed some years ago while collecting from the 

 Magothy formation at Cliffwood bduff. New Jersey. At this 

 point the clays are full of pyritized cones which are identical
