folia, Podogonium acuminatum, Leguminosites serrulatus, L. species, An- 

 tholithes amcenus, A. improhus, Garpites gemmaceus, C. Milioides. 



(3) General remarks. Table of distribution of the plants of the Green 

 Kiver and White Eiver groups. 



(4) Kelatiouship of the local groups indicated by correlation of spe- 

 cies. The plants which have heretofore been referred by the author to 

 the Green Eiver group represent two different horizons : Green Eiver 

 Station, Eandolph Company, and Alkali Station for one, Florissant, 

 White Eiver, and Elko for a second. The materials obtained at the first 

 are too scant to afford any indication of their reference to any ijarticular 

 stage of the Tertiary ; they may represent a lower group than that of 

 the Florissant, but what is said of the relationshii) of these plants au- 

 thorizes a contrary conclusion. Considers the flora of Florissant prob- 

 ably synchronous with that of the Oligocene of France. 



lY. Miocene flora : 



(1) Description of Miocene species from specimens obtained in the 

 so-called Bad Lands of Dakota. The following are new species : Asple- 

 nium tenerum, Equisetum glubosum, Quercus Dentoni, Ficus artocarpoides, 

 Tetranthera prwcursoria, Cinchonidium ovale, Viburnnm daliotense, V. 

 Dtntoni, Aralia aeerifolia, Acer gracilescens, Rhus Winchellii, Prunus 

 dakotensis, Gercis truncata. 



(2) Description of Miocene species of California and Oregon. The 

 following species are new : Betula parce-dentata, Alnus corrallina, A. car- 

 pinoides, Quercus Breweri, Ulnus pscudo-americana, Ficus asiminafolia, 

 Laurus grandis, L. salicifolia, L. californica, Greicia auriculata, Allan- 

 thus ovata, Myrtus oregonensis, Golutca howeniana. 



(3) Contributions to the Miocene flora of Alaska. The following spe- 

 cies are new: Thuites {Ghama;cyparis) AlasJcensis, Comptonia cnspidata, 

 G. prccmissa, Betula Alaskana, Alnus corylifolia, Quercus Dallii. 



(4) Species of plants from the chalk bluffs of California, 



(5) Table of distribution of the Xorth American Miocene fossil plants. 



(6) Eemarks on the species of Miocene plants. The author concludes 

 that as the fossil floras of Carbon and the Bad Lands are related bv 

 ten identical species, and those of the Bad Lands and Alaska by thir- 

 teen, these three groups apparently represent the same stage of the 

 North American Miocene. The flora of Carbon has only four species 

 identified in that of Alaska, but their lesser degree of afliuity may be 

 ascribed to difference in latitude.
