If we examine the above table candidly we discover at once that 
our suspicion that the Waverly is not homogeneous is abundantly sub- 
stantiated, and not less noticeable is the difference in habitus between 
these assemblages. The lines chosen as the outlines of our divisions 
were selected because they mark shore deposits and thus are transition 
zones, as the deposits of a progressing or retreating littoral zone must 
always be with regard to the sea-basin deposits formed before and after 
the fluctuation in level producing the movement. Certainly no other 
lines will prove more convenient in Licking county, though all such 
zones may be arbitrary as regards other areas. Now in number I, ex- 
tending say loo feet below congl. I, the fauna, as so far worked, pre- 
sents about the following relations : Species of carboniferous habit, 2 
or 3 ; species with decidedly Devonian habit (often closely related to 
Hamilton species), 25; species not found outside this zone or if so in 
horizons still -under discussion, 30. In No II, embracing all between 
congl. I and II, species with carboniferous habit, possibly 9 ; species 
with Devonian affinities (often Chemung species) 12; species which
