by Dr. Newberry as new was 45, and the number by Mr 
Lesquereux was 47. Nine species ‘from Fort Ellsworth, foe 
= included in Mr. Lesquereux’s list, the descriptions of 
which did not appear until the following year,” do not enter 
sto the figures above given. It will thus be seen that about 
seventy-five species of Dicotyledons had been described from 
the Dakota Group and other American Uretaceous strata down _ 
to the year 1869. 
Far less could be said for Europe at this date. Hosius,” in — 
1869, was able to enumerate in his Geognosie Westfalens twenty- 
five characteristic species of the eaten which had been 
described and figured either by Von der Marck” or by himself.” 
In this year, ts Heer published his Fossil Flora of i im 
Mihren, which belongs to the lower Quadersandstein ase 
Cenomanian. ‘Twelve species are described and "carafe 
gured. 
In Hayden’s annual reports of the geological survey of the 
Territories for 1870 and 1871” Lesquereux continues to enlarge 
the list of American species, and in 1872, Heer,” in his Fossid 
Flora of Quedlinburg makes further additions to that of Europe. 
Weare thus brought down to the year 1874, which 18 : 
marked by three very important publications. 
Schimper’s Traité de Paléontologie Végétale was completed in 
that year, in the fourth volume® of which 109 species of Creta- 
ceous Dicotyledons are recognized. Of these 46 are American, 
which shows that the ued was far behind in the literature of 
the subject. He also expresses serious doubts as to the Creta- 
33. species in the higher strata of Atane, which are mow gener- & ‘
