A single fragment was found which appears to represent 

 this species. 



A number of complete specimens not yet determined are 

 in the collection, besides hundreds of fragments, some (mono- 

 cotyledonous), too fragmentary to permit of positive identifi- 

 cation. 



Thanks are due F. H. Knowlton, of Washington, D. C, 

 for assistance in making the determinations here recorded. 

 The locality has never been adequately worked by the col- 

 lector. It is hoped that future effort may result in bringing 

 to light a much larger list of these most interesting organic 

 remains.
