hamites elegans, Moriconia cyclotoxon, Magnolia Woodbridg- 
ensts, Laurophyllum angustifolium, Aralia palmata, Ficus 
Woolsont, Paliurus tntegrifolius and Celastrophyllum New- 
berryanum, and all except possibly Paliurus and Chondrites 
with well-characterized remains. Of the numerous species 
which are identical with those of the Dakota group of the 
West only eight are confined to the Dakota and Matawan 
formations. There are twenty-three species identical with 
Dakota group forms, but it may be remarked that the latter 
horizon is not precisely defined and its flora is exceptionally 
well known. 
Fifteen of the Matawan species are found in the Raritan 
Cretaceous of the islands; nine occurring on Staten Island, 
eight on Long Island, seven on Martha’s Vineyard, and four 
on Block Island. Eleven of the Matawan species reappear 
in the Atane beds of Greenland, and one additional in the 
Patoot beds; of these several are dominant forms of great 
vertical or areal distribution, or both, and thus have little sig- 
nificance; such forms are Seguota Leichenbachi, Sapindus 
Morrisoni, Laurus plutonta and Andromeda Parlatori. 
Others are more suggestive; thus, exclusive of its occurrence 
in the clays at Aachen, Aorzconza is confined to the ancient 
Atlantic coastal plain and Greenland, and its remains are com- 
mon; several species of Magnolia emphasize the similarity 
of these floras, as does the presence of the large-leaved Aralia 
avniana. This species is confined to the Atane and Mata- 
wan floras in so far as I can judge from the published descrip- 
tions or figures of Aralias, and its remains are unmistakably 
characterized. Dewalguea Groenlandica is also confined to 
these floras. With the Potomac flora as elaborated by Fon- 
taine there seems to be no affinity, and the time that elapsed 
between them must have been very long. 
Of species which occur in the Cenomanian of Europe we 
have Geinitzia formosa, Sequoia Rerchenbachi, Cunning- 
hamuites squamosus, Cunninghamites elegans, Moriconta cyclo- 
toxon, Sassafras acutilobum, Laurus plutonta, Banksia 
pusilla, Sapindus apiculatus and Eucalyptus Geinitz:, a
