uplift of twenty-five feet in Virginia to four hundred to five hun-

The Paleozoic strata at the eastern end of Lake Ontario has a

present terraces north of Lake Ontario are certainly marine), and 
that of the adjustment to the present relative elevation of land

race epoch.— F. W. Spencer, Ph.D., F.G.S., University of Missouri,

The Formations of the Belly River of Canada.—In his report 
on the geological survey of the Dominion, Mr. George M. Daw- 
son describes a new formation, to which he gives the name of 
the Belly River epoch. 
The deposit is immediately overlaid by the Pierre or number 
four cretaceous of Meek and Hayden, which in turn is overlaid 
by the Laramie. The Belly River beds are of lacustrine origin. 
Tt is well known that the Pierre beds are of marine origin, while 
the Laramie beds are lacustrine. The Pierre fauna of the Do- 
minion is identical with that already known, while the Belly River 
` beds also contain numerous fossil remains. e plants have been 
studied by Sir William Dawson, who finds them to be identical 
with those of the Laramie. The same conclusions have been 
reached by Mr. Whiteaves as to the Mollusca, and Professor Cope 
finds the vertebrates, of which there are numerous species, to be 
identical with those of the Laramie. It is difficult to believe that 
the same land fauna continued during two geological epochs so 
generally different as those of the Pierre and those of the Laramie. 
It is also difficult to believe that a deep-sea marine fauna could 
have occupied the interior of the continent during the stage of 
elevation presented by the Laramie. It is therefore suspected that
