Vicksburg Militar\- Park, Warren County, Mississippi (the Bluff 

 formation of Hilgard). 



The number of species in these tAvo collections is small and 

 the forms are not especially noteworthy in that the\' do not 

 occur outside the existing range of the forms invoh^ed. The hack- 

 berry {Celtis mississippiensis) is recorded for the first time from 

 the Pleistocene; Lesquereux's old determination of the chin- 

 quapin froni the banks of the Mississippi River is in a measure 

 corroborated by finding it fossil in western Tennessee; and the 

 range of the Pleistocene ancestor of the Spanish oak is consider- 

 ably extended. Following are the species recognized with brief 

 annotations: 



OSMUNDA (?) sp. 



Based upon roots tocks collected by Mr. Wade at Adamsville. 

 Similar remains, likewise referred to Osmunda, were described 

 by Hollick^ from the late Pleistocene (Talbot formation) of 

 Maryland, and the foliage of Os?nunda spectahilis Willd. occurs 

 in the Pleistocene of Alabama.^ 



QuERCUS PREDIGITATA Berry. 



This form, the supposed ancestral type of the existing Quercus 

 digitata and Qnerciis pagodaefolia, has been recorded previously 

 from the Pleistocene of North Carolina,^ Mississippi,'* and Vir- 

 ginia.^ It is represented at Adamsville by leaves, cupules and 

 acorns, thus considerably extending its known range. 



Castaxea pumila Miller. 



The small chestnut or chinquapin has been recorded by 

 Knowlton^ from the Pleistocene near Morgantown, West Vir- 

 ginia, and by Lesquereux''' from the early Pleistocene near Co- 

 lumbus, Kentucky. Although I have collected materials from 

 Lesquereux's locality and adjacent outcrops^ I did not meet
