can be found in but a few places. Personally, in all my field- 
work in the Cleveland shale, for example, I have seen but a 
handful of imperfect specimens of Eodon bellistriatus, most of 
which were gathered by Dr. Clark in his labors on the fossil 
fishes. He has also now in his possession a large cephalopod 
like Gyroceras undulatum, but not yet described. The utter 
barrenness of these massive shales must be seen to be fully ap- 
preciated.
