apparently a broad fruit which answers to the following description : — • 



Peduncle 1 mm. broad and 8 mm. long, bearing at its upper end a broad, four-sided 

 disc 12 mm. at the base, 6 mm. wide at the summit and 8 mm. high, without structural 

 markings of any kind except a finely granulated surface strongly suggestive of the 

 presence of small seeds or akenes. While the observed form may have been derived 

 from crushing, the entire aspect of the specimen, together with the granulated sur- 

 face, strongly suggests a fruit of the type of Dorstenia. 



If the suggestion thus indicated may be relied upon, it would harmonize 

 with the very general occurrence of representatives of the TTrticacese in Creta- 

 ceous formations, such as Ulmus, Ficus, etc. The specimen might be referred 

 provisionally to Dorstenia.

Undeterminable. 



Several specimens under* number

show fragments of dichotomously 



branching remains which cannot be satisfactorily correlated with any known 

 species. They strongly suggest a variety of well-known forms, including 

 Hymenopteris, Czekanowskia, Baieropsis, Potamogeton and Naias, with none of 

 which a satisfactory relation can be established; and upon careful consideration
