The Waverly Group in Ohio — Herrick. 97 
express great similarity with the Hamilton and Portage. A 
considerable number of species are indistinguishable from 
Hamilton forms,* others are obviously related but have at least 
varietal differences. In the characteristic chocolate beds of 
the Bedford in the Cuyahoga valley and near Columbus the 
same association of forms has been found with no admixture of 
Waverly species. This we desire to make prominent in view of 
the published statement of Dr. Newberry that Syringothyris 
etc. occur in the Bedford. The accompanying plate illustrates 
the above statement. (Plate n.) 
Fourth, in spite of what has been said, it is true that a very 
few' species extend with very slight variation, from the lower 
into the middle, and from the middle into the upper division,, 
while a still smaller number appear to ascend from the middle 
of division i into division hi. A number of species thought to* 
give to the Waverly a decidedly Carboniferous aspect do not 
apparently enter the Waverly at all. Such are Productus 
cora, Chonetes mesoloba, Productus nebrascensis, etc. In some* 
cases the mistake seems to be the result of false identification, 
while in others an accidental commingling or confusion of 
gatherings has been responsible. 
It is not necessary to burden these remarks with lists of 
species as these are presented in the paper referred to. But it 
should be noticed that the statements above made indicate that 
there is no serious hiatus in the column from the Hamilton to- 
the Coal Measures. In other words, we may here trace with 
some degree of confidence the changes in fauna gradually 
supervening under rather constant conditions through an
