about forty species of plants from deposits of this age in that 

 state. Among these there were five members of the family 

 Juglandaceae represented by leaflets o{ Jiiglans, Hicoria, and pos- 

 sibly Pterocarya (although the latter is doubtfully determined), 

 and a small poorly preserved nut of Hicoria. 



Remains of Hicoria, both leaflets and nuts, have proved to be 

 very common in such of our Pleistocene deposits south of the 

 terminal moraine as have been exploited. Juglans, on the other 

 hand, has thus far proved to be exceedingly rare. 



I am indebted to Dr. F. H, Knowlton, of the U. S. National 

 Museum, for the privilege of describing the present exceptionally 

 well preserved specimens which were collected from the Talbot 



formation, about one mile south of Chesapeake Beach in Calvert 

 County by WilHam Palmer. 

 Hicoria glabra (Mill.) Britton. 



Several extremely well preserved specimens of the fruit of this 

 species were collected some of which are shown in figs. 1-5. 

 These bring out very well the pear-shaped outline, the indehis- 

 cent husk, and the thick shell which characterize the modern
