 is described by Prof. Heer, from the Cretaceous of Greenland.

Paliurus AFFiNis, Heer ? 



PI. II. f. 12, 14, 18, 19. 



PI. III. f. 7. 



It is with some hesitation that these specimens have been 

 referred to the above sj^ecies. They are all incomplete and 

 fragmentary but show indications of a triple nervation similar 

 to Palim'us, or perhaps Cinnamomum. There also seems to be 

 an indication of trilobation, as in f. 12, PI. II, and it is possible 

 that several genera may be here grouped together, but only 

 by means of more complete material could this be demon- 

 trated satisfactorily. All are from the clays at Kreischerville 

 except f. 7, PI. Ill, which represents a specimen found in a 

 concretion at Tottenville, 



LiRIODENDRON PRIM^VUM, Ncwb. 



PI. III. f. 4
