This paper was prepared in collaboration 

 with Walter P. Jenney, William M. Fontaine, 

 and F. H. Knowlton. 



The specimens described are in the Mnseum 

 collection. They include 86 species, and are 

 from the lower part of the Cretaceous forma- 

 tion, from the beds that extend down from 

 the Dakota group to the upper part of the 

 .lurassic. One new genus and 36 new species 

 are described.

 This paper is based partly upon Museum 

 material. The locality of the specimens de- 

 scribed is given as the Freezeout Hills, north 

 of Medicine Bow, in Carbon County, Wyo. 

 The new genus to which the 20 species are 

 referred is OycadeUa.

 The collections, which include about 75 spe- 

 cies, Avere made at thirteen localities. They 

 have been arranged in three groups; First, 

 that from the horizon of the McAlester coal; 

 second, a group from about 2,000 feet above the 

 Mc.-Vlcstcrcoal: andthird, a group of localities 

 from which a flora was collected belonging 

 to a coal horizon about 1,500 feet below the 

 McAlester coal. Comparing these with the 

 Carboniferous divisions of the Old World, the 

 Me.\lester flora is said to be clearly Stephan- 

 ian and comparable to the flora of the Upper 

 Coal Measures of Great Britain. The upper 

 group belongs to a horizon some distance 

 below the Permian, while the lower flora is 

 plainly Wcstphalian, having close relations 

 with the Middle or Lower Coal Measures of 

 Great Britain. The fos.sil floras indicate a 

 very great expansion of the coal measures in 

 Indian Territory.

 The greater portion of the specimens de- 

 scribed in this paper were derived from two 

 horizons about 45 feet apart. The plants 

 described are concluded to be contempora- 

 neous with the flora of the uppermost zone of 

 the Westphalian of the Franco-Belgian Basin, 

 and other coal fields of Europe.
